Rheumatoid polyneurop w rheumatoid arthritis of right ank/ft

This code signifies a neurological complication of rheumatoid arthritis (RA) affecting multiple peripheral nerves, specifically in the right ankle and foot. It indicates that the polyneuropathy is directly attributable to the underlying rheumatoid disease process.

Apply this code when documentation clearly states a diagnosis of rheumatoid polyneuropathy in a patient with rheumatoid arthritis, with the specific anatomical involvement of the right ankle and foot. Physician notes should confirm the causal link between the RA and the polyneuropathy.

• Ensure documentation specifies "polyneuropathy" rather than mononeuropathy or other neurological manifestations.
• Verify laterality (right) and specific joint involvement (ankle and foot) are explicitly stated.
• Always sequence the underlying rheumatoid arthritis code (e.g., from the M05 category) as the primary diagnosis, followed by this code as a secondary diagnosis.
