Article Overview
This premium article examines a coding question involving ICD-10-CM obstetric documentation and the use of an additional code for obesity when the condition is not further specified. It is intended for coders, CDI staff, auditors, and revenue cycle teams who need to interpret tabular-list notes, unspecified diagnoses, and facility-level coding policy in an obstetric setting. The article also addresses the broader issue of how internal policies may affect reporting practices when documentation does not identify a more specific type.
