Unspecified diabetes mellitus in childbirth

This code signifies diabetes mellitus of an unspecified type occurring during the peripartum period, specifically during childbirth. It indicates that the patient has diabetes, but the specific classification (e.g., pre-existing Type 1, Type 2, or gestational) is not documented.

Apply this code when a pregnant patient with an unclassified type of diabetes delivers. Documentation must clearly state "diabetes in childbirth" without further specification of the diabetes type. This code is appropriate when the provider has not specified if the diabetes is pre-existing or gestational.

• Always seek clarification from the provider if the type of diabetes is not specified to assign a more precise code.
• This code should be sequenced as a secondary diagnosis when the reason for the encounter is the delivery.
• Avoid using this code if documentation specifies gestational diabetes (O24.4-) or a pre-existing type of diabetes (O24.0-, O24.1-, O24.3-).
