What This Code Means
N80.361 is the ICD-10-CM diagnosis code for superficial endometriosis of the right pelvic brim. Superficial endometriosis affecting the right pelvic brim, where the tissue involvement is limited to the surface layers. N80.361 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering noninflammatory disorders of female genital tract (n80-n98).
N80.361 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.
Distinguish between pelvic sidewall codes (N80.35x, N80.36x) and pelvic brim codes (N80.36x, N80.37x).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N80.361 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
