About M06.8

M06.8 is the ICD-10-CM diagnosis code for other specified rheumatoid arthritis. It belongs to category M06 (other rheumatoid arthritis), block M05-M14 (inflammatory polyarthropathies) 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 11 subcodes must be used instead.

Within M06, choose M06.8 (Other specified rheumatoid arthritis) only when documentation doesn't support a more specific option: rheumatoid arthritis without rheumatoid factor (M06.0), Adult-onset Still's disease (M06.1), rheumatoid bursitis (M06.2), rheumatoid nodule (M06.3), inflammatory polyarthropathy (M06.4) and rheumatoid arthritis, unspecified (M06.9).

To report this condition, pick the subcode that matches the documentation: M06.80 (unspecified site), M06.81 (shoulder), M06.82 (elbow), M06.83 (wrist), M06.84 (hand), M06.85 (hip), M06.86 (knee), M06.87 (ankle and foot) and 3 more.

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