Excludes1 inherited from the categories above M71.40
These are not written on M71.40, but they bind it: a note on a category applies to every code beneath it. Billing M71.40 with anything listed here is a denial.
Excludes2 inherited from the categories above M71.40
Also inherited, and the opposite of Excludes1: these conditions are not part of M71.40, but a patient can have both, so you may code both.
Risk adjustment
M71.40 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
M71.40 is named in 7 Medicare coverage policies — 0 listing it as supporting medical necessity, and 7 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
