Other specified rheumatoid arthritis, right ankle and foot

This code signifies a diagnosis of rheumatoid arthritis that affects the right ankle and/or foot, but does not fit into more specific categories of rheumatoid arthritis (e.g., with rheumatoid factor, with organ involvement). It indicates a chronic inflammatory autoimmune disease primarily impacting the synovial joints in this specific anatomical location.

Use this code when documentation specifies rheumatoid arthritis affecting the right ankle and/or foot, and the type of rheumatoid arthritis is not further detailed as seropositive, seronegative, or with other specific systemic manifestations. This code is appropriate when the physician's notes clearly identify the right ankle and foot as the affected site of rheumatoid arthritis.

• Ensure documentation specifies "other specified" or lacks details for more specific RA codes (e.g., M05.-, M06.0-).
• Verify laterality (right) and anatomical site (ankle and foot) are clearly documented.
• Do not use if the rheumatoid arthritis is explicitly stated as seropositive, seronegative, or with major organ involvement; use the more specific codes in those instances.
