Unspecified diabetes mellitus in the puerperium

This code signifies diabetes mellitus that is present or diagnosed during the postpartum period (puerperium), without further specification of the type of diabetes (e.g., pre-existing, gestational, or new onset). It indicates a diabetic condition requiring management after childbirth, where the specific etiology is not documented.

Apply this code when a patient has diabetes during the puerperium, and the medical record does not specify if it's pre-existing Type 1, Type 2, or gestational diabetes that persisted or developed postpartum. Documentation should clearly state "diabetes in puerperium" without further classification.

• Avoid using this code if the type of diabetes (e.g., pre-existing Type 1, Type 2, or gestational diabetes resolving postpartum) is clearly documented.
• Always sequence this code after the obstetric complication code (O99.810 for gestational diabetes complicating puerperium, or O99.814 for other specified diabetes complicating puerperium) if applicable.
• Query the provider for clarification on the type of diabetes if possible, to allow for more specific coding.
