M24.1 — Other articular cartilage disorders
M24.1 is a non-billable header ICD-10-CM code for other articular cartilage disorders. It cannot be billed on its own: choose one of the more specific child codes below.
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.
Excludes1 inherited from the categories above M24.1
These are not written on M24.1, but they bind it: a note on a category applies to every code beneath it. Billing M24.1 with anything listed here is a denial.

Excludes2 inherited from the categories above M24.1
Also inherited, and the opposite of Excludes1: these conditions are not part of M24.1, but a patient can have both, so you may code both.
Risk adjustment
M24.1 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
M24.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about M24.1
- Is M24.1 a billable ICD-10-CM code?
- No. M24.1 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does M24.1 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 M24.1?
- M24.1 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 M24.1 (M24) and apply to it just the same.
