About coding baby blues
The ICD-10-CM code for baby blues is O90.6 (Postpartum mood disturbance).
Within O90 (complications of the puerperium, not elsewhere classified), O90.6 is specifically for postpartum mood disturbance. 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 acute kidney failure (O90.4), postpartum thyroiditis (O90.5), other complications of the puerperium, not elsewhere classified (O90.8) and complication of the puerperium, unspecified (O90.9).
Don't report O90.6 together with the conditions in its Excludes1 note: postpartum depression (F53.0) and puerperal psychosis (F53.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for O90.6)
