About coding disorder puerperal

The ICD-10-CM code for disorder puerperal is O90.9 (Complication of the puerperium, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O90.9.

Within O90, choose O90.9 (Complication of the puerperium, unspecified) only when documentation doesn't support a more specific option: disruption of cesarean delivery wound (O90.0), disruption of perineal obstetric wound (O90.1), hematoma of obstetric wound (O90.2), Peripartum cardiomyopathy (O90.3), postpartum acute kidney failure (O90.4), postpartum thyroiditis (O90.5), postpartum mood disturbance (O90.6) and other complications of the puerperium, not elsewhere classified (O90.8).

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.
