Rheumatoid polyneuropathy w rheumatoid arthritis mult site

This code signifies nerve damage (polyneuropathy) directly caused by rheumatoid arthritis (RA) affecting multiple joints throughout the body. The polyneuropathy is a systemic manifestation of the underlying autoimmune inflammatory process.

Apply this code when documentation clearly links a patient's polyneuropathy to their rheumatoid arthritis, specifically when the RA affects more than one joint region. Supporting documentation should include a diagnosis of rheumatoid arthritis, evidence of polyneuropathy (e.g., nerve conduction studies, neurological exam findings), and a physician's statement confirming the causal relationship.

• Ensure the documentation explicitly states "rheumatoid polyneuropathy" or a similar phrase indicating the RA as the etiology of the polyneuropathy.
• Do not use this code if the polyneuropathy is due to another cause, even if the patient also has RA.
• This code inherently includes the "multiple sites" aspect of the rheumatoid arthritis; no additional RA site codes are typically needed for the RA itself when using this specific combination code.
