Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Gout NOS
Risk adjustment
M10.9 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
M10.9 is named in 11 Medicare coverage policies — 5 listing it as supporting medical necessity, and 6 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
