Pre-existing type 2 diabetes mellitus, in childbirth

AIClinical Context

Clinical Description

This code signifies a pregnant patient with a pre-existing diagnosis of type 2 diabetes mellitus who is currently in the process of childbirth. It indicates that the patient's chronic diabetic condition is impacting or being managed during the labor and delivery period.

When to Use

Apply this code when a patient with an established diagnosis of type 2 diabetes is admitted for labor and delivery. Documentation should clearly state "type 2 diabetes" and indicate the patient is "in childbirth" or "during delivery."

Coding Tips

Always sequence this code after the primary obstetric code indicating the reason for admission (e.g., normal delivery, complicated labor).
Do not use this code for gestational diabetes; specific codes exist for that condition.
Ensure documentation specifies "type 2" diabetes; "diabetes mellitus" alone is insufficient.
