Cracking the Code
Coding Obstetric Complications That Span Trimesters
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.
