M25.579 — Pain in unspecified ankle and joints of unspecified foot

Risk adjustment

M25.579 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.

M25.579 is named in 16 Medicare coverage policies — 4 listing it as supporting medical necessity, and 12 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
