M71 — Other bursopathies

Non-billable headerICD-10-CM

M71 is a non-billable header ICD-10-CM code for other bursopathies. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

bunion (M20.1)
bursitis related to use, overuse or pressure (M70.-)
enthesopathies (M76-M77)

Other codes that can never be billed with M71

These codes carry an Excludes1 note pointing at M71. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M71 alone.

M70Soft tissue disorders related to use, overuse and pressure
M71.5Other bursitis, not elsewhere classified
M77Other enthesopathies

Risk adjustment

M71 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.

Code to one of these instead M71

8 child codes. Green means billable.
