Other specified rheumatoid arthritis, other specified site

This code signifies a form of rheumatoid arthritis that doesn't fit into more specific categories, affecting a particular anatomical location not otherwise classified. It indicates a documented diagnosis of rheumatoid arthritis with atypical features or presentations in a specific joint or body region.

Apply this code when the medical record explicitly states "other specified rheumatoid arthritis" or details a variant of rheumatoid arthritis impacting a site not covered by more granular codes (e.g., rheumatoid arthritis of the ankle, wrist, or shoulder without further specification). Documentation should clearly identify both the rheumatoid arthritis and the affected site.

• Ensure the documentation specifies a particular site; if the site is unspecified, a different code may be more appropriate.
• Do not use this code for rheumatoid arthritis with systemic involvement or specific organ manifestations, as those have dedicated codes.
• Always sequence this code after the primary diagnosis if it represents a manifestation or complication of another condition.
