ICD-10 Code M05.532 – Rheumatoid polyneuropathy with rheumatoid arthritis of left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.532 – Rheumatoid polyneuropathy with rheumatoid arthritis of left wrist
What it is
This code identifies rheumatoid arthritis affecting the left wrist, with associated polyneuropathy. It tells you the joint disease and the nerve involvement are both documented.
Clinical signs
Expect inflammatory wrist findings such as pain, swelling, stiffness, and reduced motion, plus symptoms of polyneuropathy like numbness, tingling, or weakness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states rheumatoid arthritis of the left wrist and rheumatoid polyneuropathy are present together. It is appropriate when the provider links the neuropathy to rheumatoid disease. Check documentation if laterality or the neuropathy relationship is unclear.
Do not use for
Do not use it for rheumatoid arthritis without documented polyneuropathy, or for neuropathy from another cause. Do not assume left wrist involvement if the chart only says wrist or multiple joints.
Coding tip
Verify both the rheumatoid arthritis site and the neuropathy linkage before assigning M05.532.
