D17.23 — Benign lipomatous neoplasm of skin and subcutaneous tissue of right leg
D17.23 is a billable, specific ICD-10-CM code for benign lipomatous neoplasm of skin and subcutaneous tissue of right leg. It is valid for submission on a claim.

Risk adjustment
D17.23 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.
Medicare coverage
D17.23 is named in 12 Medicare coverage policies — 12 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
