About coding postpartum cardiomyopathy
The ICD-10-CM code for postpartum cardiomyopathy is O90.3 (Peripartum cardiomyopathy).
Within O90 (complications of the puerperium, not elsewhere classified), O90.3 is specifically for Peripartum cardiomyopathy. Related codes cover disruption of cesarean delivery wound (O90.0), disruption of perineal obstetric wound (O90.1), hematoma of obstetric wound (O90.2), postpartum acute kidney failure (O90.4), 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).
Don't report O90.3 together with the conditions in its Excludes1 note: pre-existing heart disease complicating pregnancy and the puerperium (O99.4-).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
Don't confuse with (Excludes1 for O90.3)
- pre-existing heart disease complicating pregnancy and the puerperium (O99.4-)
