Written on M19 — Other and unspecified osteoarthritis

polyarthritis (M15.-)

Excludes2 inherited from the categories above M19.07

Also inherited, and the opposite of Excludes1: these conditions are not part of M19.07, but a patient can have both, so you may code both.

Written on M19 — Other and unspecified osteoarthritis

arthrosis of spine (M47.-)
hallux rigidus (M20.2)
osteoarthritis of spine (M47.-)

Risk adjustment

M19.07 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.

M19.07 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
