Is M24.5 a billable ICD-10-CM code?

No. M24.5 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does M24.5 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Other joint disorders (M20-M25).

What cannot be coded together with M24.5?

M24.5

M24.5 — Contracture of joint

Non-billable headerICD-10-CM

M24.5 is a non-billable header ICD-10-CM code for contracture of joint. 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 muscle without contracture of joint (M62.4-)
contracture of tendon (sheath) without contracture of joint (M62.4-)
Dupuytren's contracture (M72.0)

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.

acquired deformities of limbs (M20-M21)

Other codes that can never be billed with M24.5

These codes carry an Excludes1 note pointing at M24.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M24.5 alone.

M25.6Stiffness of joint, not elsewhere classified
M62.4Contracture of muscle

Risk adjustment

M24.5 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 M24.5

9 child codes. Green means billable.
