What This Code Means
Z37.62 is the ICD-10-CM diagnosis code for quadruplets, some liveborn. A pregnancy with four babies where at least one was born alive and at least one was stillborn. Z37.62 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons encountering health services in circumstances related to reproduction (z30-z39).
Z37.62 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.
Confirm the delivery record documents four fetuses with mixed liveborn and stillborn outcomes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z37.62 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm the delivery record documents four fetuses with mixed liveborn and stillborn outcomes
- •Document the exact number of liveborn versus stillborn infants in the medical record
