What This Code Means
O99.344 is the ICD-10-CM diagnosis code for other mental disorders complicating childbirth. A pregnant woman has a mental health disorder (other than depression or anxiety) that complicates the actual labor and delivery process. O99.344 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering other obstetric conditions, not elsewhere classified (o94-o9a).
O99.344 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code when the mental disorder actively affects the childbirth experience or management.
