M62.4 — Contracture of muscle
M62.4 is a non-billable header ICD-10-CM code for contracture of muscle. 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.
- contracture of joint (M24.5-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Contracture of tendon (sheath)
Excludes1 inherited from the categories above M62.4
These are not written on M62.4, but they bind it: a note on a category applies to every code beneath it. Billing M62.4 with anything listed here is a denial.
Excludes2 inherited from the categories above M62.4
Also inherited, and the opposite of Excludes1: these conditions are not part of M62.4, but a patient can have both, so you may code both.
Other codes that can never be billed with M62.4
These codes carry an Excludes1 note pointing at M62.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M62.4 alone.
- M24.5Contracture of joint
Risk adjustment
M62.4 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 history
M62.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about M62.4
- Is M62.4 a billable ICD-10-CM code?
- No. M62.4 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does M62.4 sit in the tabular list?
- Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Disorders of muscles (M60-M63).
- What cannot be coded together with M62.4?
- M62.4 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above M62.4 (M62) and apply to it just the same.
