O90.4Postpartum acute kidney failure

O90.4 is the ICD-10-CM diagnosis code for postpartum acute kidney failure. It belongs to category O90 (complications of the puerperium, not elsewhere classified), block O85-O92 (complications predominantly related to the puerperium) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within O90 (complications of the puerperium, not elsewhere classified), O90.4 is specifically for postpartum acute kidney failure. Related codes cover 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 thyroiditis (O90.5), postpartum mood disturbance (O90.6), other complications of the puerperium, not elsewhere classified (O90.8) and complication of the puerperium, unspecified (O90.9).

To report this condition, pick the subcode that matches the documentation: O90.41 (delivery) and O90.49 (failure).

Don't report O90.4 together with the conditions in its Excludes1 note: anuria and oliguria (R34).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2024 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 669.32 (acute kidney failure following labor and delivery, delivered, with mention of postpartum complication) and 669.34 (acute kidney failure following labor and delivery, postpartum condition or complication).
