M05.7Rheumatoid arthritis with rheumatoid factor without organ or systems involvement

M05.7 is the ICD-10-CM diagnosis code for rheumatoid arthritis with rheumatoid factor without organ or systems involvement. 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 10 subcodes must be used instead.

Within M05, choose M05.7 (without organ or systems involvement) only when documentation doesn't support a more specific option: Felty's syndrome (M05.0), rheumatoid lung disease with rheumatoid arthritis (M05.1), rheumatoid vasculitis with rheumatoid arthritis (M05.2), rheumatoid heart disease with rheumatoid arthritis (M05.3), rheumatoid myopathy with rheumatoid arthritis (M05.4), rheumatoid polyneuropathy with rheumatoid arthritis (M05.5), rheumatoid arthritis with involvement of other organs and systems (M05.6), other rheumatoid arthritis with rheumatoid factor (M05.8) and 2 more.

To report this condition, pick the subcode that matches the documentation: M05.70 (involvement), M05.71 (involvement), M05.72 (involvement), M05.73 (involvement), M05.74 (involvement), M05.75 (involvement), M05.76 (involvement), M05.77 (involvement) 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.
