Risk adjustment
C44.1292 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.

C44.1292 is named in 89 Medicare coverage policies — 85 listing it as supporting medical necessity, and 4 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
