M24.2 — Disorder of ligament
M24.2 is a non-billable header ICD-10-CM code for disorder of ligament. 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.
- familial ligamentous laxity (M35.7)
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.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Instability secondary to old ligament injury
- Ligamentous laxity NOS
Other codes that can never be billed with M24.2
These codes carry an Excludes1 note pointing at M24.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M24.2 alone.
Risk adjustment
M24.2 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 M24.2
