Rheumatoid polyneuropathy w rheumatoid arthritis of unsp hip

This code signifies a peripheral nerve disorder, specifically polyneuropathy, that is directly caused by or associated with rheumatoid arthritis. The rheumatoid arthritis itself affects an unspecified hip joint. This indicates a systemic autoimmune condition manifesting with both joint inflammation and neurological complications.

Apply this code when documentation clearly states a diagnosis of rheumatoid polyneuropathy in a patient with rheumatoid arthritis. The medical record must also specify involvement of an unspecified hip. This code is appropriate when the polyneuropathy is explicitly linked to the underlying rheumatoid arthritis.

• Ensure documentation specifies "polyneuropathy" and not just "neuropathy" to differentiate from mononeuropathy.
• Verify the laterality of the hip is not specified in the medical record; if it is, a more specific code should be used.
• Always sequence the underlying rheumatoid arthritis code (e.g., M05.xx) first, followed by this code for the neurological manifestation.
