M67.2 — Synovial hypertrophy, not elsewhere classified
M67.2 is a non-billable header ICD-10-CM code for synovial hypertrophy, not elsewhere classified. 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.
- villonodular synovitis (pigmented) (M12.2-)
Excludes1 inherited from the categories above M67.2
These are not written on M67.2, but they bind it: a note on a category applies to every code beneath it. Billing M67.2 with anything listed here is a denial.
Risk adjustment
M67.2 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 history
M67.2 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
