Gestational diabetes in childbirth, insulin controlled

This code signifies gestational diabetes that is currently managed with insulin during the delivery of a baby. It indicates that the patient developed diabetes during pregnancy and requires insulin to maintain glycemic control during the peripartum period.

Use this code for pregnant patients experiencing active labor or delivery who have a documented diagnosis of gestational diabetes and are receiving insulin therapy. Documentation should clearly state "gestational diabetes," "in childbirth," and "insulin controlled."

• Always sequence this code after the obstetric code indicating the type of delivery (e.g., O80, O82).
• Do not use this code if the patient's diabetes was pre-existing (Type 1 or Type 2) before pregnancy; use codes from category O24.0 or O24.1 instead.
• Ensure documentation explicitly states "insulin controlled" versus "diet controlled" or "oral hypoglycemic controlled" to avoid miscoding.
