Is N71.9 an HCC code?

No. N71.9 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

N71.9 is the ICD-10-CM diagnosis code for inflammatory disease of uterus, unspecified. Inflammation of the uterus where the specific type (acute or chronic) is not clearly documented or specified. N71.9 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering inflammatory diseases of female pelvic organs (n70-n77).

N71.9 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 the documentation does not clearly indicate whether the condition is acute or chronic.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N71.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Use only when the documentation does not clearly indicate whether the condition is acute or chronic
  • Query the provider if possible to determine the appropriate acute (N71.0) or chronic (N71.1) code
