Gestational proteinuria, complicating childbirth

This code signifies the presence of proteinuria that develops during pregnancy and persists through childbirth, without evidence of hypertension or other pre-existing renal disease. It indicates a transient renal dysfunction specifically occurring in the peripartum period.

Apply this code when documentation confirms new-onset proteinuria during pregnancy, specifically noted as complicating the delivery or postpartum period, and the patient does not have gestational hypertension or pre-eclampsia. Supporting documentation should clearly state "gestational proteinuria" or "proteinuria of pregnancy" in the context of childbirth.

• Differentiate from pre-eclampsia (O14.-) or gestational hypertension with significant proteinuria (O13.-).
• Ensure documentation specifies "complicating childbirth" for accurate code assignment.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is the delivery.
