What This Code Means
O77.1 is the ICD-10-CM diagnosis code for fetal stress in labor or delivery due to drug administration. Fetal stress or distress during labor or delivery caused by medications administered to the mother. O77.1 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering complications of labor and delivery (o60-o77).
O77.1 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.
Always document which drug was administered and link to the appropriate drug code if applicable.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O77.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
