ICD-10 Code M05.53 – Rheumatoid polyneuropathy with rheumatoid arthritis of wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.53 – Rheumatoid polyneuropathy with rheumatoid arthritis of wrist
What it is
This code identifies rheumatoid arthritis of the wrist with associated polyneuropathy. Use it when documentation links the nerve disorder to the rheumatoid disease and specifies the wrist involvement.
Clinical signs
Findings may include chronic inflammatory wrist pain, swelling, stiffness, and sensory or motor nerve symptoms in more than one peripheral nerve. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatoid arthritis affecting the wrist and also states polyneuropathy due to rheumatoid disease. It is appropriate when the neuropathy is part of the same rheumatoid condition, not a separate nerve disorder. Check documentation if the causal 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 assign it if the wrist site or rheumatoid link is not specified.
Coding tip
Confirm both the wrist site and the rheumatoid cause before coding, because this combination code is only correct when both are documented.
