Cracking the Code
Coding Cancer Correctly
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).
