Is P19.0 an HCC code?
No. P19.0 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
P19.0 is the ICD-10-CM diagnosis code for metabolic acidemia in newborn first noted before onset of labor. A condition where a newborn's blood becomes too acidic due to metabolic problems, detected before labor begins. P19.0 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering respiratory and cardiovascular disorders specific to the perinatal period (p19-p29).
P19.0 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.
This code requires documentation of the timing (before labor onset) to distinguish it from P19.1 and P19.2.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P19.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
