When reviewing medical records pertaining to incision and drainage/excision procedures, it is very important for a coder to locate documentation supporting the depth of the procedure. For ICD-10-PCS procedure codes, there are different codes provided for incision and drainage of skin and incision and drainage of subcutaneous tissue and fascia. To ensure that a coder is selecting the most appropriate code, it is imperative to have a firm understanding of skin vs subcutaneous tissue.
The skin is the outer layer of the body. The subcutaneous tissue is the deepest layer underneath the skin. When coding incision and drainage/excision procedures, it is important to code to the deepest layer. If a provider’s documentation states that an incision and drainage/excision was performed on skin and subcutaneous tissue, then it is appropriate to report the PCS code for the subcutaneous layer.
A surgeon performed an open incision and debridement of the right knee anterior soft tissues and prepatellar bursal area to include excision of compromised skin and subcutaneous tissue and superficial fascia with placement of wound VAC.

Sometimes, newborns are admitted for observation and evaluation of suspected conditions. Per ICD-10-CM Official Guidelines for Coding and Reporting FY 2021, it is appropriate to report a diagnosis code from category Z05, observation and evaluation of newborns and infants for suspected conditions ruled out. A code from this category identifies when a healthy newborn is evaluated for a suspected condition that is determined to not be present after the provider completes a full study of the newborn. Z05 should ONLY be reported if the newborn does not have any signs and symptoms. If the newborn has confirmed signs and symptoms of a suspected problem, then it is appropriate to report the signs and symptoms instead. Lastly, when Z05 is reported on a birth record, it is important to sequence the diagnoses correctly. A diagnosis from category Z38, liveborn infants should be reported as the primary diagnosis followed by a code from category Z05 as a secondary diagnosis.
0-hour-old, 39 weeks gestation male newborn who was delivered vaginally presents with fast breathing. The provider admits the newborn into observation to study the breathing. The newborn stayed for three days before the provider confirmed to rule out the condition.

IV Hydration GuidanceFebruary 11, 2021
When a patient enters the emergency department (ED), an intravenous (IV) site full of pre-packaged fluids and electrolytes is typically started for the purpose of providing hydration. Hydration is basically the replacement of necessary fluids. As a medical coder, it is very important to have a firm understanding of when to report and how to accurately report hydration procedures. Some of the solutions that are administered for hydration are saline solutions, dextrose 5% water (D5W), hypotonic solution, ringer lactate, and distilled water (DW).
In order to properly report hydration procedures, it is important to have a firm understanding of when and how to report them. Hydration services are NOT reportable when the fluid is used to flush an IV line prior or subsequent to another infusion; when the fluid is used as the diluent to mix the drug; and when the hydration’s purpose is to accommodate a therapeutic IV piggyback through the same IV site as a free-flowing IV.
On the other hand, hydration services can be reported if the hydration is administered before or after a therapeutic or prophylactic drug infusion and chemotherapeutic service. It is very important that there is clear supporting documentation from the provider showing medical necessity for the hydration. Signs and symptoms such as dehydration or nausea with vomiting needs to be documented for proper reporting of a hydration procedure.References: Coding Clinic for HCPCS First Quarter 2012 pages 1-4: IV push, infusion vs hydration
Discontinued ProceduresFebruary 4, 2021
Per ICD-10-PCS Official Guidelines for Coding and Reporting FY 2021, section B3.3 instructs to code the procedure to the root operation performed if the intended procedure is discontinued or otherwise not completed. Furthermore, the code root operation Inspection of the body part or anatomical region inspected should be reported if a procedure is discontinued before any other root operation is performed.
A 27-year-old patient with known history of intravenous drug abuse and asthma is admitted for acute hypoxemic respiratory failure secondary to severe asthma exacerbation. Per ED provider’s notes, the patient was coughing up large amounts of phlegm with a possibility of aspiration. Thus, the patient was intubated, and bronchoscopy was performed. Bronchoscopy findings showed that there were inflammations of bronchial mucosa, and both lungs with the presence of secretion were suctioned. However, the procedure was aborted because of significant desaturation and evidence of bronchospasm. (Coding tip: suctioning of the secretions was performed prior to the discontinuation of the procedure, so it should be coded to the root operation “drainage.”)

Principal diagnosis for observation converted to inpatient statusJanuary 27, 2021
Selection of the principal diagnosis is crucial for correct DRG assignment and reporting of the patient’s condition. When a patient is converted from a medical or surgical Observation status to an Inpatient, the principal diagnosis should be the condition that necessitated Inpatient admission. Per ICD-10-CM Official Guidelines for Coding and Reporting FY 2021, the principal diagnosis is defined as “the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.” This diagnosis may be different from the reason for the initial Observation care.
A patient is admitted to Observation status after being evaluated in the ED for chest pain, shortness of breath, and cough. The physician orders a chest x-ray and results show that the patient has right lower lobe pneumonia. Upon these results, the physician decides to convert the patient to Inpatient status to run more in-depth tests and provide extra treatment for the pneumonia.
J18.9, pneumonia, unspecified organism
Principal Diagnosis Guidelines – Two Interrelated ConditionsJanuary 20, 2021
Direct guidance from the coding guidelines state that either condition may be sequenced first when two or more interrelated conditions potentially meet the definition of principal diagnosis. The interrelated conditions refer to diseases in the same ICD-10-CM chapter or manifestations characteristically associated with a certain disease. The ONLY exception to this rule is when the circumstances of the admission, the therapy provided, the Tabular List, or the Alphabetic Index indicate otherwise. If there are no chapter-specific guidelines or instructional notes under the code description for sequencing, then either condition can be listed as the primary diagnosis.
A 63-year-old female with a past medical history significant for congestive heart failure with EF of 35-40%, severe aortic stenosis status post TAVR, cardiac arrest post AICD implantation, type 2 diabetes, is admitted for pre-syncope and hypotension. Hypotension – secondary to diuretic use, decreased oral intake, and daughter reported possible laxative abuse to the ED provider. Per discharge summary, patient has a final diagnosis of hypotension-hypovolemia due to poor PO intake and diuretic use.
Per coding guideline section II.B., either the hypotension or the hypovolemia can be sequenced as the primary diagnosis.
I95.9, hypotension, unspecified
PFIZER & MODERNA CPT Vaccination CodesJanuary 13, 2021
Effective December 2020, The U.S. Food and Drug Administration (FDA) issued the first emergency use authorization for a vaccine for the prevention of COVID-19 in individuals 16 years of age and older. During the clinical trials, The Pfizer/BioNTech was 95% effective at preventing laboratory-confirmed COVID-19 illness in people without evidence of previous infection. Currently, the FDA is working on approving a second vaccine for immediate emergency use called Moderna. It is hopeful that this vaccine will have the same outcome as the Pfizer vaccine.
Both vaccinations have their own unique vaccine and administration codes. Both vaccines have two administration codes since they both will be administered in two doses via intramuscular method. The American Medical Association (AMA) has already created CPT codes for reporting the COVID-19 vaccines.
The vaccine code for Pfizer/BioNTech is 91300, and the administration codes are 0001A (for the first dose) and 0002A (for the second dose). The vaccine code for Moderna is 91301, and the administration codes are 0011A (for the first dose) and 0012A (for the second dose).References: American Medical Association
Updated COVID-19 DiagnosisJanuary 8, 2021
Effective immediately as of January 1st, 2021, there are new diagnosis codes pertaining to COVID-19!
Z11.52, encounter for screening for COVID-19 (previously used Z11.59; reported for people who are asymptomatic and test negative)
Z20.822, contact with and (suspected) exposure to COVID-19 (previously Z20.828)
Z86.16, personal history of COVID-19 (previously used Z86.19)
J12.82, pneumonia due to coronavirus disease 2019 (previously used J12.89). Includes the inclusion terms, “pneumonia due to COVID-19” and “pneumonia due to severe acute respiratory syndrome coronavirus 2”. Existing coding guidance (prior to 1/1/21) for COVID-19-related pneumonia instructs coders to report two ICD-10-CM codes for the condition: U07.1 (COVID-19) and J12.89 (other viral pneumonia). As of 1/1/21, AHA now recommends that BOTH U07.1 and J12.82 be reported for viral pneumonia due to COVID-19.
M35.81, multisystem inflammatory syndrome (previously used M35.8)
The information is fluid, and we are currently staying abreast. We will be sure to distribute more details once we discover more information.References: AHA Frequently Asked Questions
Discontinued Procedures for PCS CodesDecember 16, 2020
A discontinued procedure is one that is canceled or not fully accomplished under the procedure definition. Per ICD-10-PCS Coding Guidelines Section B3.3, it is appropriate to code the procedure to the root operation performed if the intended procedure is discontinued. If a procedure is discontinued before any other root operation is performed, then the code root operation Inspection of the body part or anatomical region inspected. It is the coder’s responsibility to recognize whether a procedure was performed in its entirety in order to properly code it.
When reviewing the provider’s documentation, it is important to look for key words that highlight a discontinued procedure (such as aborted, attempted, abandoned, failed, incomplete, or unsuccessful). Here are a couple of helpful coding tips when reviewing medical record documentation:
Accurately Reporting Newborn with ComplicationsDecember 10, 2020
The perinatal period is defined as before birth through the 28th day following birth. Coders should utilize chapter 16 ICD-10-CM coding guidelines when coding newborn records. When coding the birth episode in a newborn record, a code from category Z38, liveborn infants should be assigned as the principal diagnosis. Coding guidelines also instruct coders to code all clinically significant conditions noted on routine newborn examinations. A condition is clinically significant if it requires clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of hospital stay, increased nursing care, or implications for future health care needs.
0-hour-old birth weight TBD. AGA 39 weeks gestation male newborn presents asymptomatic.
Delivery type: spontaneous vaginal delivery
Assessment: term newborn delivered vaginally, current hospitalization
Passage of meconium during delivery affecting newborn
Z38.00, single liveborn infant, delivered vaginally
P03.82, meconium passage during delivery
ICD-10-CM Guidelines for DiabetesDecember 2, 2020
Per FY 2021 ICD-10-CM Guidelines for Coding and Reporting, there is updated information in the section pertaining to the chapter specific guidelines for coding diabetes mellitus. This information can be reviewed under section I.C.4.a.3. titled “Diabetes mellitus and the use of insulin, oral hypoglycemics, and injectable non-insulin drugs” and section I.C.4.a.6. titled “Secondary diabetes mellitus”.
“If the documentation in a medical record does not indicate the type of diabetes but does indicate that the patient uses insulin, code E11-, Type 2 diabetes mellitus, should be assigned. An additional code should be assigned from category Z79 to identify the long-term (current) use of insulin or oral hypoglycemic drugs. If the patient is treated with both oral medications and insulin, only the code for long-term (current) use of insulin should be assigned. If the patient is treated with both insulin and an injectable non-insulin antidiabetic drug, assign codes Z79.4, Long-term (current) use of insulin, and Z79.899, Other long term (current) drug therapy. If the patient is treated with both oral hypoglycemic drugs and an injectable non-insulin antidiabetic drug, assign codes Z79.84, Long-term (current) use of oral hypoglycemic drugs, and Z79.899, Other long-term (current) drug therapy. Code Z79.4 should not be assigned if insulin is given temporarily to bring a type 2 patient’s blood sugar under control during an encounter.”References: ICD-10-CM Official Guidelines for Coding and Reporting FY 2021, Section I.C.4.a.
Initial vs Subsequent: The 7th CharacterNovember 17, 2020
Sometimes, there is confusion about when to assign the seventh character for diagnosis codes S00-T88 with “A” for initial encounter or “D” for subsequent encounter. “Initial encounter” for an injury does not always equate to an “initial visit.” Per Chapter 19 of FY2021 ICD-10-CM Official Guidelines for Coding and Reporting, assignment of the seventh character is based on whether the patient is undergoing active treatment and not whether the provider is seeing the patient for the first time.
Some examples of active treatment are surgical treatment, emergency department encounter, and evaluation and treatment by a new physician. Some examples of routine care during the recovery phase are cast change or removal, removal of external or internal fixation device, medication adjustment, and other aftercare and follow up visits following injury treatment.
In conclusion, active treatment occurs when the provider sees the patient and develops a plan of care. The patient following that plan is when a subsequent encounter occurs. If the patient is receiving active treatment for their condition, then it is appropriate to assign “A” for the seventh character. If the patient has completed active treatment for their condition but is receiving routine care during the healing or recovery phase, then it is appropriate to assign “D” for the seventh character.References: ICD-10-CM Official Guidelines for Coding and Reporting FY 2021, Section I.C.19.a.
NIH VS GCS Stroke ScoringNovember 11, 2020
In the medical coding field, there is often confusion about when to report the National Institutes of Health Stroke Scale (NIHSS) and Glasgow Coma Scale (GCS) scores. Per FY2021 ICD-10-CM Official Guidelines for Coding and Reporting, a GCS score (R40.2-) is used in conjunction with traumatic brain injury to identify the severity of an acute brain injury. On the other hand, a NIHSS score (R29.7–) is used in conjunction with acute stroke codes (I63) to identify the patient’s neurological status and severity of the stroke.
Both scores are to be sequenced after the traumatic brain injury code (for GCS) or acute stroke code (for NIHSS).References: FY2021 ICD-10-CM Official Guidelines for Coding and Reporting Sections I.C.18.e. and i
Observation Service Code ObservationsNovember 5, 2020
Observation care reporting can be a challenging area of medical coding. Patients are commonly ordered for observation services when they present to the emergency department and then require an extensive period of treatment/monitoring in order to determine their admission or discharge. Here are some helpful tips on how to successfully report observation service codes:

Coding Permanent Dual-chamber PacemakersOctober 29, 2020
Sick sinus syndrome (SSS) is a disorder of the heart’s natural pacemaker. Typically, SSS is treated with an implanted pacemaker. A pacemaker consists of a small, battery-powered generator and one or more leads. With a single-chamber system, only one lead is used. With a double-chamber system, two leads are used and placed in the right atrium and right ventricle.
ICD-10-PCS Codes: 0JH606Z, Insertion of pacemaker generation, 02H63JZ, insertion of device in atrium, and 02HK3JZ, insertion of device in ventricle
CPT Codes: 33208, insertion of new or replacement of permanent pacemaker with transvenous electrode(s); atrial and ventricular
A patient presents to the ED with complaints of sick sinus syndrome. The physician admits the patient and determines that surgery intervention is necessary. A permanent dual chamber pacemaker with atrial and ventricular leads was implanted. An incision was made into the left chest wall with the dual chamber pacemaker being placed in the subcutaneous pocket. Next, a small incision was made into the skin and the leads were percutaneously passed into the right ventricle and right atrium
I49.5, sick sinus syndrome
Getting to the Point of an IVR Lumbar PunctureOctober 22, 2020
Interventional radiology (IVR) uses minimally invasive image-guided procedures (such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound) to diagnose and treat diseases inside of the body. There is much less risk, pain, and recovery time for IVR procedures compared to open surgeries. A lumbar puncture (sometimes referred to as a spinal tap) is an example of an IVR procedure that reveals if the amount of protein, white blood cells, or myelin is too high in your body. It can also reveal if the fluid in your spine contains an abnormal level of antibodies. By analyzing this fluid, the physician can diagnose the patient with a condition.
A patient enters an orthopedic office with complaints of muscle spasms/pain, stiffness, and weakness. The physician performs a fluoroscopic lumbar puncture in order to collect spinal fluid to test for certain antibodies. The patient tolerates the procedure well and is instructed to return in two months in order to review the findings.
ICD-10-PCS Code: 009U3ZX, Drainage of Spinal Canal, Percutaneous Approach, Diagnostic CPT Code: 62328, Spinal puncture, lumbar, diagnostic; with fluoroscopic or CT guidance
Updated Glasgow Coma Scale Guidance for FY2021October 15, 2020
For FY2021 ICD-10-CM Official Guidelines for Coding and Reporting, CMS revised the guideline for the Glasgow Coma Scale (GCS). Per the updated guidance, “The coma scale codes (R40.2-) can be used in conjunction with traumatic brain injury codes. These codes are primarily use by trauma registries, but they may be used in any setting where this information is collected. The coma scale codes should be sequenced after the diagnosis code(s).”
Per the updated guidelines, the GCS score will NO longer be applicable to acute cerebrovascular disease or sequelae of cerebrovascular disease codes starting with October 1st, 2020 discharges. Furthermore, the GCS score may NOT also be used to assess the status of the central nervous system for other non-trauma conditions, such as monitoring patients in the intensive care unit regardless of medical condition.
There may be further clarification with this updated guidance in the AHA Coding Clinic for Fourth Quarter 2020. However, for now, these are the official updated guidelines for GCS score.Reference: ICD-10-CM Official Guidelines for Coding and Reporting Section I.C.18.e: Coma scale
Coding Diagnostic vs Therapeutic ProceduresOctober 8, 2020
The main factor when considering whether a procedure is diagnostic or therapeutic is to determine the objective of the procedure. If the main objective is to establish a diagnosis for the patient prior to starting any kind of treatment, then it is considered to be a diagnostic procedure. If a diagnosis is already established and a procedure is completed in order to eradicate a problem, then it is considered to be a therapeutic procedure. For drainage root operations, the ICD-10-PCS guidelines state that if a diagnostic procedure is followed by a more definitive procedure (therapeutic) then both the diagnostic and more definitive treatment are coded.
A patient comes in for a biopsy of their left pleural cavity via thoracentesis. During the same encounter, the physician also performs a therapeutic thoracentesis from the right side of the patient's chest.

Coding for CirrhosisOctober 1, 2020
Cirrhosis is the most common type of liver disease. Most of the patients who have cirrhosis develop esophageal varices due to scarring throughout the liver. Since the esophageal varices are due to the scarring (which is caused by cirrhosis), cirrhosis is sequenced as the primary diagnosis followed by varices as a secondary diagnosis. Also, coders should be sure to follow the instructional note under I85.11 that states to “code first underlying disease”.
When reviewing cases with esophageal varices, please be sure to look for documentation specifying the underlying cause. If the provider does NOT document the etiology of the varices, please query for clarification.
A 73-year-old male with history of cirrhosis and colon cancer (status-post resection and colectomy) presents with episodes of hematemesis and blood in colostomy bag. The provider performs an EGD and finds bleeding esophageal varices. The provider performs esophageal banding in order to stop the bleeding.

Coding Obstetric Complications That Span TrimestersSeptember 24, 2020
When an obstetric patient is admitted to a hospital for complications of pregnancy during one trimester and remains in the hospital into a subsequent trimester, then it is appropriate to report the trimester character for when the complication developed. For example, if a patient is admitted into inpatient status for a complication during their second trimester but is in their third trimester at the time of discharge, then the correct character assignment for the antepartum complication code should be for the second trimester.
A patient who is currently 13 weeks pregnant arrives to the ED complaining of cough and shortness of breath. The physician is made aware that the patient has been in contact with someone who previously had COVID-19. The patient is admitted and tested for COVID-19. The results are positive for Coronavirus and pneumonia. The patient is treated for their diagnoses. At the time of discharge, the patient is now 14 weeks pregnant.

Principal diagnosis with POA “N”September 17, 2020
It is the responsibility of the inpatient coder to assign a Present on Admission (POA) Indicator for all principal and secondary diagnosis codes as defined in Section II of the Official Coding Guidelines. The “Y” indicator is for when a diagnosis is present at the time admission while the “N” indicator is for when a diagnosis is not present at the time of inpatient admission. The “U” indicator is for when documentation insufficient to determine if condition is present at the time of inpatient admission. Lastly, the “W” indicator is for when a provider is unable to clinically determine whether the condition was present at the time of inpatient admission.
According to the POA Reporting Guidelines, the coder should assign “N” if at least ONE part of the clinical concepts included in the code was NOT present on admission. This would also be appropriate for primary diagnoses. Here are a few examples of these instances below:
Alcohol dependence when withdrawal symptoms occur after admission
Chronic obstructive pulmonary disease when exacerbation occurs after admission
Gastric ulcer when bleeding occurs after admission
Asthma when asthmaticus occurs after admission
Duodenal ulcer when the perforation occurs after admission

Coding Incision and Drainage ProceduresSeptember 3, 2020
Coding incision and drainage procedures can often be very frustrating! The key is to break down the procedure(s) into pieces.
Key tips to ask yourself while coding incision and drainage procedures:
Coding GI Conditions with BleedingAugust 27, 2020
Gastrointestinal (GI) bleeding is not a disease but a symptom of a disorder in a person’s digestive tract. There are many possibilities that may cause GI bleeding, including hemorrhoids, peptic ulcers, diverticulosis/diverticulitis, ulcerative colitis, Crohn’s disease, colonic polyps, or gastritis (just to name a few examples). Per ICD-10-CM Official Guidelines for Coding and Reporting Section I.A.15 “With” guideline, it is safe to presume a causal relationship between two conditions when it is linked by the term “with” or “in” when it appears in a code title. In that case, when a provider documents that a patient has one of the previously mentioned conditions (among other conditions) and GI bleeding, then it is appropriate to assume a relationship between the disorder and bleeding. The ONLY time it is not acceptable is when documentation clearly states that the conditions are unrelated or if the physician documents a different cause of the bleeding.
A 65-year-old patient arrived at the hospital with complaints of weakness and fatigue. The patient also complains of GI bleeding over the past few days. The physician performs an EGD to determine the cause of bleeding. In conclusion, the EGD does not provide a specific source of the bleeding; however, gastric ulcers were revealed.
K25.4, chronic or unspecified gastric ulcer with hemorrhage
Selecting the Appropriate Primary DiagnosisAugust 20, 2020
Selecting the principal (primary) diagnosis is one of the most important steps when coding a medical record. It is very important that a medical coder uses a patient’s entire medical record to determine the selection of a principal diagnosis and not rely solely on the admission information nor discharge summary. Selecting the correct principal diagnosis reduces compliance risk while capturing reimbursement and medical diagnosis codes with integrity. The Uniform Hospital Discharge Data Set (UHDDS) defines principal diagnosis as “the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.” It is important to review all parts of the medical record (history and physical, progress notes, orders, consultation notes, operative reports, and discharge summary) in order to ensure that the correct principal diagnosis is reported.
A 62-year-old patient with a personal history of chronic anemia, upper gastrointestinal (GI) bleed, and Barrett’s esophagus presented for bloody stools. The patient was admitted for further treatment and care. During the patient’s stay, an EGD was completed. The results for the EGD stated that the patient had non-bleeding esophageal ulcers at the esophagogastric junction (GEJ), two gastrojejunal anastomotic ulcers (one with a visible vessel; coagulation for hemostasis), and status-post gastric bypass with patent Roux-en-Y anastomosis. The physician plans to repeat the upper EGD in two months to check the healing process and advises the patient not to take any aspirin, ibuprofen, naproxen, or other non-steroidal anti-inflammatory drugs.

Intrathoracic injuries with rib fracturesAugust 13, 2020
“When reviewing medical records where the physician has documented that a patient has both an intrathoracic injury and a rib fracture, it is important to remember that the intrathoracic injury is sequenced first followed by the rib fracture diagnosis. Per instructional note for diagnosis codes that fall under the range of S22, it is advised to code first any associated injury of intrathoracic organ (S27.-) or spinal cord injury (S24.0-, S24.1-).
A 64-year-old patient presents to the ED with complaints of significant pain over the left side of his body (including the shoulder and left posterior chest wall) after a fall from a ladder while painting the outside of their home. The patient was admitted for further trauma evaluation and care. The physician orders a CT of the chest, abdomen, and pelvis, and the final impression states that the patient has a comminuted nondisplaced fracture of the posterior left sixth and seventh ribs. There is also tracing of left pneumothorax.
S27.0XXA, traumatic pneumothorax, initial encounter S22.42XA, multiple fractures of ribs, left side, initial encounter for closed fracture W11.XXXA, fall on and from ladder, initial encounter Y92.007, garden or yard of unspecified non-institutional (private) residence as the place of occurrence of the external cause
Coding Wound Debridement ProceduresAugust 6, 2020
Wound debridement is a medical procedure that removes infected, damaged, or dead tissue. The physician’s documentation needs to be descriptive enough to create a very clear picture of the procedure performed. Here are some important tips for reporting wound debridement procedures:
Lumbar Coding From Front to BackJuly 30, 2020
Sometimes, coders will come across lumbar spinal fusion procedures that involve both anterior and posterior approaches. Typically, there is an incision in the front of the body through the abdomen (anterior) and then another incision in the lumbar or lower back region (posterior).
A woman is admitted to the hospital with lumbar spondylolisthesis and lumbar spinal stenosis. The surgeon performs a lumbar laminectomy. He used up ankle curettes to release the dura from its attachment to the medial facet capsule. Foraminotomies were then performed. From a left-sided approach, the surgeon placed a Trelloss transforaminal lumbar interbody fusion spacer. Pars interarticularis on the left side was resected along with the superior aspect of the L3-4 and L4-L5 facets. Trelloss banana-shaped titanium cages were then placed into the disc space and tapped as anterior as possible toward the anterior part of the disc space. Behind the cages morselized local autograft bone was then packed into the disc space. A Trocar was advanced into the iliac crest on the right side. Bone marrow was harvested and iliac crest bone marrow was mixed with the morselized local autograft bone and was laid over the decorticated posterolateral gutters for purposes of arthrodesis from L3-L5 bilaterally.

Coding Gastrointestinal Conditions with BleedingJuly 23, 2020
Are you often stumped with deciding whether to code gastrointestinal (GI) conditions with or without bleeding? The cause for GI bleeding isn’t always easily determined; however, there’s guidance from the coding guidelines that help us with selecting the proper diagnosis codes in these cases. Let’s review…
If two conditions are linked by the terms “with” or “in” in the Alphabetic Index or instructional note in the Tabular List, then there’s a presumed causal relationship between those conditions. The ICD-10-CM Coding Guidelines FY 2020 Section I.A.15 state “these conditions should be interpreted to mean “associated with” or “due to” when it appears in the code title UNLESS the provider documentation clearly states the conditions are unrelated or when another guideline exists that specifically requires a documented linkage between the two conditions.
The following are some common conditions that have a causal relationship with GI bleeding: peptic ulcers, varices, gastritis, colitis, duodenitis, diverticulosis/diverticulitis, colon or rectal polyps, angiodysplasia, ulcerative esophagitis or esophageal ulcerations, intestinal tumor or malignancy, and trauma.
A patient who previously tested positive for COVID-19 is seen for a follow-up exam. The physician orders lab testing once again, and the results are now negative for COVID-19.
Z09, Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm
Historical Versus Active COVID 19 CodesJuly 16, 2020
History codes are reported when a physician’s documentation specifies that a patient no longer has a condition. There is not a particular timeframe for personal history conditions; if a patient is diagnosed with pneumonia but no longer has pneumonia during a follow-up visit, then a coder would assign a code for personal history of pneumonia. This same rule applies when reporting personal history of COVID-19. U07.1, positive COVID-19 is ONLY reported if documentation supports a confirmed diagnosis. If it is documented that the patient was positive for COVID-19 weeks ago but no longer has the condition during their current encounter, then the coding guidelines state that a personal history code should be reported.
A patient who previously tested positive for COVID-19 is seen for a follow-up exam. The physician orders lab testing once again, and the results are now negative for COVID-19.
Z09, Encounter for follow-up examination after completed treatment for conditions other than malignant neoplasm
Coding Cancer CorrectlyJuly 9, 2020
Accurately coding cancer diagnoses all depends on clear documentation from the provider. How do you know when cancer is historical or active? Cancer is considered to be active when the patient is currently and actively being treated and managed for cancer (i.e. current chemotherapy, current pathology revealing cancer, or newly diagnosed patient awaiting treatment).On the other hand, cancer is considered to be historical when the cancer was successfully treated and patient is no longer receiving treatment (i.e. cancer was excised or eradicated, patient using adjuvant therapy for prophylactic purposes, or patient is under surveillance of recurrence).

Coding COVID-19 Patient Lung Transplant StatusJuly 2, 2020
When a patient is admitted for management of respiratory manifestations of COVID-19 and is also status-post lung transplant, the coding guidelines state that lung transplant infection diagnosis should be sequenced as the primary diagnosis followed by U07.1, COVID-19 as a secondary diagnosis. It is VERY important to pay attention to the sequencing of the diagnoses. The Tabular List note at the lung transplant infection code states to “use additional code to specify infection”, and coding guidelines state “a transplant complication code is only assigned if the complication affects the function of the transplanted organ.” In this scenario, the COVID-19 infection has affected the function of the transplanted lung.
Patient presents to the ED with cough and shortness of breath. The patient has history of lung cancer and lung transplantation. The physician orders a lab to test for COVID-19, and the results are positive for the virus.
T86.812, lung transplant infection U07.1, COVID-19
What NOT to Code for a Spinal FusionJune 25, 2020
When coding spinal fusion procedures, it is important to determine which procedures are integral and which are not integral. If the procedure is considered to be integral, then additional, separate codes are NOT assigned. If the procedure is not considered to be integral, then it is appropriate to assign separate codes.
*Pedicle screw instrumentation is included in the spinal fusion.
A patient presents to the ED with severe lower back pain that continues to progress in severity. The physician orders a CT scan of the lumbar region. Final impression: degenerative disc disease L2-L5, herniated disc L4-L5, and scoliosis. The patient is admitted to inpatient status, and the physician performs a L2-L5 posterior lumbar interbody fusion using autologous bone graft, L2-L5 discectomy, L2-L5 pedicle screw instrumentation, and harvesting bone graft from right iliac crest through separate incision.

Coding Consciousness: What’s your GCS?June 17, 2020
The Glasgow Coma Scale (GCS) is used to assess reduced levels of consciousness in patients. It is the most reliable way to objectively record the initial and subsequent level of consciousness in a person after a brain injury. It is comprised of three components that are considered separately and summed: eye opening (E), verbal response (V), and motor responses (M). The GCS provides a score in the range of 3 (deep coma or brain death) – 15 (fully awake and aware), and patients that have a score of 3-8 are usually defined as being in a coma. Please pay close attention to physician’s documentation in order to capture the accurate GCS score. If documentation does NOT state the total coma score, then a diagnosis code from subcategory R40.24 should NOT be assigned.
This equation simply states that the eye opening measured at a level 2, verbal response measured at a level 4, and motor response measured at a level 6. The sum of all three components results in a total of 12. The number 12 is the GCS score for this patient.
Physician documents GCS 12 = E2 V4 M6 at 5:52 AM at hospital admission.
R40.2423, Glasgow coma scale score 9-12, at hospital admission
Spinal Fusion Code CautionsJune 11, 2020
Spinal Fusion coding can be an area of apprehension for a lot of coders! Coding opportunities sometimes are buried within the body of operative reports which makes it even more challenging. First and foremost, be sure to read the entire report to capture all pertinent codes.
Consider the following snippet, which comes from an actual operative report and supports the assignment of 0SG0071 (fusion of lumbar vertebral joint with autologous tissue substitute, posterior approach, posterior column, open approach):
“I then loaded the tulip-heads onto the screw shanks, and I then placed a Creo addition titanium rod. Posterior instrumentation replaced from the L3-4 interspace modular loading cross connector to L1 pedicle screw. I contoured lordosis in the back table before placement into the Tulip head. Final tightened compressed at L1-2. I used a high-speed bur to decorticate the facet on the left side at L1-2, and the transverse process bilaterally of L1-L2 and placed local bone and osteosurge to complete a posterolateral fusion.”
New Telehealth Therapy ReimbursementsJune 4, 2020
Telehealth services allow a physician or other approved licensed care provider with the ability to provide services and effectively communicate with their patients via secure telecommunication devices. As of April 30, 2020, CMS has expanded the list of approved telehealth services to include physical therapy (PT), occupational therapy (OT), and speech therapy (ST). Please be sure to check with individual third-party payers about their policies in order to receive full reimbursement.
A 50-year-old Medicare patient consents to a remote evaluation service with their Physical Therapist. The patient has questions about whether they are performing the recommended exercises correctly. The patient records themselves and sends it off to the Physical Therapist for review via email. After reviewing the video, the Physical Therapist calls the patient on the telephone to provide further instruction on how to properly perform the exercise.
G2010 (remote evaluation of recorded video and/or images submitted by an established patient, not originating from a related e/m service provided within the previous 7 days nor leading to an e/m service or procedure within the next 24 hours or soonest available appointment). GP modifier is added to indicate this is a physical therapy service.
Coding CHF with Pleural EffusionMay 28, 2020
Pleural effusion is a typical disorder that is seen in patients who have congestive heart failure. It is an abnormal accumulation of fluid within the pleural space. If the physician completes therapeutic intervention or diagnostic testing for the pleural effusion, then it is acceptable to report it as a secondary diagnosis. If the physician does NOT specifically evaluate or treat the pleural effusion separately from the congestive heart failure, then it should NOT be reported as a secondary diagnosis.
A patient is admitted into the inpatient setting with congestive heart failure and pleural effusion. The congestive heart failure is monitored with chest x-rays, and the physician also completes an additional lateral decubitus x-ray to assess the volume of pleural effusion. The patient's final diagnosis is congestive heart failure with pleural effusion.
150.9, heart failure, unspecified J91.8, pleural effusion in other conditions classified elsewhere (acceptable secondary diagnosis because of the additional x-ray to assess the volume)
Coding Tips: Sequencing Multiple InjuriesMay 21, 2020
When a patient presents to the hospital for treatment of multiple injuries, it is appropriate to code all of the injuries for accurate reporting purposes. All of the injuries should be reported separately unless there is a combination diagnosis code provided for those conditions. The injury that is sequenced first is the injury that is determined by the physician and focus of treatment to be the most serious.
A 45-year-old patient presents to the ED with complaints of left shoulder, leg and ankle pain after falling off a ladder while painting her home. The physician places orders for x-rays. The imaging results reveal a pilon fracture of the left tibia and a sprain of the left AC joint of the shoulder. The patient is discharged home with a splint applied to the left foot.

What’s the latest code for Vaping-related disorders?May 14, 2020
Starting April 1, 2020, the World Health Organization (WHO) implemented a brand new ICD-10-CM diagnosis code: U07.0, vaping-related disorder. This is being implemented now due to the recent occurrences of vaping related disorders. For all discharge dates on or after April 1, U07.0 will be sequenced as the primary diagnosis IF the physician’s documentation states that the vaping caused the patient’s current condition. It is then followed by that condition as a secondary diagnosis code.
A patient presents to the emergency department with shortness of breath. The patient admits to the physician that they use electronic cigarettes on a regular basis. After a full work-up was completed, the patient was admitted into the hospital. Upon discharge, the physician provides a final diagnosis of acute respiratory distress syndrome due to the electronic cigarette usage.

Coding Changing Severity of Pressure UlcersMay 7, 2020
If a patient is admitted to a hospital with a pressure ulcer that progresses during the patient’s stay to another severity, then it’s appropriate to report two separate diagnosis codes. The first code is for the site and severity of the ulcer that was present on admission, and the second one is for the severity level that was reported during the stay.
If a patient is admitted to a hospital with a pressure ulcer that progresses during the patient's stay to another severity, then it's appropriate to report two separate diagnosis codes. The first code is for the site and severity of the ulcer that was present on admission, and the second one is for the severity level that was reported during the stay.
L89.314 (pressure ulcer of right buttock, stage 4) L89.313 (pressure ulcer of right buttock, stage 3)
What modifiers eliminate COVID-19 deductibles?April 30, 2020
On April 7, 2020, CMS proposed a new Families First Coronavirus Response Act. This act waives co-insurance and deductibles for additional COVID-19 related services. Under this act, CMS requires modifier CS applied to applicable institutional and non-institutional claim lines to identify that the service is subject to the cost-sharing waiver for COVID-19 testing-related services. This ensures that Medicare members are NOT charged any co-insurance or deductibles for those services as well.
A 30-year-old male presents to the hospital emergency department with a fever, cough, and shortness of breath. The physician orders a CDC COVID-19 lab test, and the results are positive.

When is COVID-19 NOT the primary diagnosis?April 23, 2020
When COVID-19 meets the definition for principal diagnosis, it should be sequenced first followed by all other appropriate secondary diagnoses. There is an exception for sepsis, obstetric, and newborn patients. However, if sepsis does NOT meet the guidelines for principal diagnosis, it should be sequenced as a secondary diagnosis. Please see the example below:
A 52 year old woman was admitted to the hospital with pneumonia due to COVID-19 virus. During the patient's stay, she developed viral sepsis. What's the correct primary diagnosis?
