M05.63Rheumatoid arthritis of wrist with involvement of other organs and systems

M05.63 is the ICD-10-CM diagnosis code for rheumatoid arthritis of wrist with involvement of other organs and systems. It belongs to category M05 (rheumatoid arthritis with rheumatoid factor), 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 3 subcodes must be used instead.

Within M05.6, choose M05.63 (wrist with involvement of other organs and systems) only when documentation doesn't support a more specific option: unspecified site with involvement of other organs and systems (M05.60), shoulder with involvement of other organs and systems (M05.61), elbow with involvement of other organs and systems (M05.62), hand with involvement of other organs and systems (M05.64), hip with involvement of other organs and systems (M05.65), knee with involvement of other organs and systems (M05.66), ankle and foot with involvement of other organs and systems (M05.67) and multiple sites with involvement of other organs and systems (M05.69).

To report this condition, pick the subcode that matches the documentation: M05.631 (systems), M05.632 (systems) and M05.639 (systems).

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