About M06.3
M06.3 is the ICD-10-CM diagnosis code for rheumatoid nodule. 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 10 subcodes must be used instead.
Within M06 (other rheumatoid arthritis), M06.3 is specifically for rheumatoid nodule. Related codes cover rheumatoid arthritis without rheumatoid factor (M06.0), Adult-onset Still's disease (M06.1), rheumatoid bursitis (M06.2), inflammatory polyarthropathy (M06.4), other specified rheumatoid arthritis (M06.8) and rheumatoid arthritis, unspecified (M06.9).
To report this condition, pick the subcode that matches the documentation: M06.30 (unspecified site), M06.31 (shoulder), M06.32 (elbow), M06.33 (wrist), M06.34 (hand), M06.35 (hip), M06.36 (knee), M06.37 (ankle and foot) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
