Rheumatoid polyneuropathy w rheumatoid arthritis of left hip

This code signifies nerve damage affecting multiple peripheral nerves (polyneuropathy) that is directly caused by rheumatoid arthritis. Specifically, it indicates that the rheumatoid arthritis manifesting with this polyneuropathy is located in the patient's left hip.

Apply this code when documentation clearly links a patient's polyneuropathy to their rheumatoid arthritis, and the active rheumatoid arthritis is specified as affecting the left hip. Supporting documentation should include a diagnosis of rheumatoid arthritis, evidence of polyneuropathy, and a causal relationship between the two, with the hip joint being the site of RA.

• Ensure the documentation explicitly states "rheumatoid polyneuropathy" or otherwise establishes the causal link between RA and polyneuropathy.
• Verify the specific joint affected by rheumatoid arthritis is the left hip; laterality is crucial.
• Do not use this code for polyneuropathy from other causes or for rheumatoid arthritis without associated polyneuropathy.
