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)
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.
