Is P71.4 an HCC code?
No. P71.4 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
P71.4 is the ICD-10-CM diagnosis code for transitory neonatal hypoparathyroidism. A newborn temporarily has reduced parathyroid hormone function, leading to low calcium levels that typically resolve on its own within days to weeks. P71.4 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering transitory endocrine and metabolic disorders specific to newborn (p70-p74).
P71.4 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 is a transitory condition; document that it is expected to resolve without long-term treatment.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P71.4 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a transitory condition; document that it is expected to resolve without long-term treatment
- •Differentiate from permanent hypoparathyroidism by noting the temporary nature in the medical record
