Is P14.3 an HCC code?

No. P14.3 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

P14.3 is the ICD-10-CM diagnosis code for other brachial plexus birth injuries. Injury to the brachial plexus (network of nerves controlling the arm) during birth, other than Erb's or Klumpke's palsy. This can result in weakness or paralysis of the arm. P14.3 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering birth trauma (p10-p15).

P14.3 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.

Specify laterality (right, left, or bilateral) when documented.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P14.3 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Specify laterality (right, left, or bilateral) when documented
  • Distinguish from P14.0 (Erb's palsy) and P14.1 (Klumpke's palsy) which are more specific diagnoses
