Rheumatoid polyneurop w rheumatoid arthritis of left knee

This code signifies a specific manifestation of rheumatoid arthritis (RA) where the patient experiences polyneuropathy, a disorder affecting multiple peripheral nerves, directly attributable to their RA. The RA itself is localized to the left knee, indicating joint involvement in that specific anatomical site.

Apply this code when documentation clearly states a diagnosis of rheumatoid polyneuropathy in a patient with rheumatoid arthritis affecting the left knee. Supporting documentation should include physician notes detailing both the systemic RA diagnosis, the neurological findings consistent with polyneuropathy, and specific mention of left knee involvement.

• Always ensure the documentation explicitly links the polyneuropathy to the rheumatoid arthritis.
• Verify laterality for the affected knee; this code is specific to the left knee.
• Consider sequencing: the RA code (M05.562) is typically the primary diagnosis, with additional codes for specific symptoms or complications as appropriate.
