About coding puerperal proteinuria
The ICD-10-CM code for puerperal proteinuria is O12.15 (Gestational proteinuria, complicating the puerperium).
Within O12.1 (gestational proteinuria), O12.15 is specifically for gestational proteinuria, complicating the puerperium. Related codes cover unspecified trimester (O12.10), first trimester (O12.11), second trimester (O12.12), third trimester (O12.13) and complicating childbirth (O12.14).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedures, relative weight 1.6673) and DRG 776 (Postpartum and Post Abortion Diagnoses without O.R. Procedures, relative weight 0.6721), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
