Excludes1 inherited from the categories above M77.41

These are not written on M77.41, but they bind it: a note on a category applies to every code beneath it. Billing M77.41 with anything listed here is a denial.

Written on M77.4 — Metatarsalgia

Morton's metatarsalgia (G57.6)

Written on M77 — Other enthesopathies

bursitis NOS (M71.9-)

Excludes2 inherited from the categories above M77.41

Also inherited, and the opposite of Excludes1: these conditions are not part of M77.41, but a patient can have both, so you may code both.

Written on M77 — Other enthesopathies

bursitis due to use, overuse and pressure (M70.-)
osteophyte (M25.7)
spinal enthesopathy (M46.0-)

Risk adjustment

M77.41 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.
