What This Code Means
Z38.8 is the ICD-10-CM diagnosis code for other multiple liveborn infant, unspecified as to place of birth. A newborn from a multiple birth when the place of delivery (hospital, home, or other location) is not documented or specified. Z38.8 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).
Z38.8 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 only when delivery location cannot be determined from the medical record.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z38.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
