Abnormal glucose complicating the puerperium

This code signifies the presence of abnormal glucose levels (e.g., hyperglycemia, hypoglycemia, or impaired glucose tolerance) that arise or persist during the puerperium, the period immediately following childbirth. It indicates a metabolic complication directly related to the postpartum state, distinct from pre-existing or gestational diabetes.

Apply this code when a patient experiences new-onset or exacerbated glucose abnormalities within the 42-day postpartum period. Documentation should clearly state the abnormal glucose finding and its occurrence during the puerperium, often noted in a follow-up visit after delivery.

• Do not use this code for gestational diabetes that resolved postpartum; instead, use a code for history of gestational diabetes if applicable.
• Always sequence this code after the primary obstetric code (e.g., Z39.0 for routine postpartum care) if the patient is still within the postpartum period.
• Ensure the medical record specifies the type of abnormal glucose (e.g., hyperglycemia, impaired glucose tolerance) if known, and consider additional codes for specific conditions like postpartum diabetes if diagnosed.
