What This Code Means
D22.5 is the ICD-10-CM diagnosis code for melanocytic nevi of trunk. This code describes benign moles (melanocytic nevi) located on the trunk of the body, including the chest, back, abdomen, and sides. These are common, non-cancerous skin growths that are typically brown or tan in color. D22.5 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D22.5 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.
Verify the anatomical location is specifically the trunk (chest, back, abdomen, or flanks) rather than other body areas, as different body regions have different D22 codes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D22.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify the anatomical location is specifically the trunk (chest, back, abdomen, or flanks) rather than other body areas, as different body regions have different D22 codes
- •Confirm these are benign nevi and not suspicious or malignant lesions, which would require different coding (such as C43 for melanoma or D48.5 for uncertain behavior)
