Rheumatoid polyneurop w rheumatoid arthritis of right knee

This code signifies a neurological complication, specifically polyneuropathy, directly attributed to rheumatoid arthritis affecting the right knee. It indicates systemic inflammatory joint disease with associated peripheral nerve damage. The polyneuropathy is a manifestation of the underlying rheumatoid arthritis.

Use this code when documentation clearly states a diagnosis of rheumatoid arthritis with an associated polyneuropathy, and the rheumatoid arthritis specifically involves the right knee. Supporting documentation would include physician notes detailing both the rheumatoid arthritis diagnosis, the presence of polyneuropathy, and the specific joint involvement.

• Ensure documentation explicitly links the polyneuropathy to the rheumatoid arthritis.
• Verify the laterality of the knee involvement (right).
• Code also the specific type of polyneuropathy if further specified (e.g., G63.6 for inflammatory and toxic neuropathy in systemic connective tissue disease).
