M70.85 — Other soft tissue disorders related to use, overuse and pressure of thigh

Non-billable headerICD-10-CM

Excludes1 inherited from the categories above M70.85

These are not written on M70.85, but they bind it: a note on a category applies to every code beneath it. Billing M70.85 with anything listed here is a denial.

Written on M70 — Soft tissue disorders related to use, overuse and pressure

bursitis NOS (M71.9-)

Excludes2 inherited from the categories above M70.85

Also inherited, and the opposite of Excludes1: these conditions are not part of M70.85, but a patient can have both, so you may code both.

Written on M70 — Soft tissue disorders related to use, overuse and pressure

bursitis of shoulder (M75.5)
enthesopathies (M76-M77)
pressure ulcer (pressure area) (L89.-)

Other codes that can never be billed with M70.85

These codes carry an Excludes1 note pointing at M70.85. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M70.85 alone.

M65Synovitis and tenosynovitis
M71Other bursopathies

Risk adjustment

M70.85 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.
