What This Code Means
O77.8 is the ICD-10-CM diagnosis code for labor and delivery complicated by other evidence of fetal stress. Labor and delivery complicated by other signs of fetal stress not specified in other categories, such as abnormal fetal heart rate patterns or other concerning fetal indicators. O77.8 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).
O77.8 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 documentation shows fetal stress but doesn't fit O77.0 or O77.1 categories.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O77.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
