Non-billable headerICD-10-CM

N80.3C is a non-billable header ICD-10-CM code for endometriosis of the uterosacral ligament(s), unspecified depth. It cannot be billed on its own: choose one of the more specific child codes below.

Risk adjustment

N80.3C does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to N80.3C.
