M19.1Post-traumatic osteoarthritis of other joints

M19.1 is the ICD-10-CM diagnosis code for post-traumatic osteoarthritis of other joints. It belongs to category M19 (other and unspecified osteoarthritis), block M15-M19 (osteoarthritis) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within M19, choose M19.1 (Post-traumatic osteoarthritis of other joints) only when documentation doesn't support a more specific option: primary osteoarthritis of other joints (M19.0), secondary osteoarthritis of other joints (M19.2) and osteoarthritis, unspecified site (M19.9).

To report this condition, pick the subcode that matches the documentation: M19.11 (shoulder), M19.12 (elbow), M19.13 (wrist), M19.14 (hand), M19.17 (foot) and M19.19 (site).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
