Rheumatoid polyneurop w rheumatoid arthritis of left ank/ft

This code signifies a neurological complication of rheumatoid arthritis (RA), specifically polyneuropathy, affecting the left ankle and foot. It indicates nerve damage in multiple peripheral nerves in this specific anatomical region, directly attributed to the underlying autoimmune inflammatory process of RA.

Use this code when documentation clearly states a diagnosis of rheumatoid polyneuropathy in a patient with confirmed rheumatoid arthritis, with the neurological symptoms and findings localized to the left ankle and foot. Supporting documentation should include neurological examination findings, nerve conduction studies, and/or electromyography confirming polyneuropathy, alongside evidence of RA affecting the left ankle and foot.

• Ensure documentation explicitly links the polyneuropathy to rheumatoid arthritis, rather than other causes.
• Verify the laterality (left) and specific anatomical site (ankle and foot) are clearly stated.
• Do not use this code for mononeuropathy or other neurological complications of RA that are not polyneuropathy.
