Is M70 a billable ICD-10-CM code?

No. M70 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does M70 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Other soft tissue disorders (M70-M79).

What cannot be coded together with M70?

M70 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

M70

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

Non-billable headerICD-10-CM

M70 is a non-billable header ICD-10-CM code for soft tissue disorders related to use, overuse and pressure. 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.

bursitis NOS (M71.9-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

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

Use additional code

Add a secondary code to capture the detail described below.

external cause code to identify activity causing disorder (Y93.-)

Includes

Conditions this code covers.

soft tissue disorders of occupational origin

Other codes that can never be billed with M70

These codes carry an Excludes1 note pointing at M70. 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 alone.

M65Synovitis and tenosynovitis
M71Other bursopathies

Risk adjustment

M70 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 M70

10 child codes. Green means billable.
