ICD-10 Code M05.54 – Rheumatoid polyneuropathy with rheumatoid arthritis of hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.54 – Rheumatoid polyneuropathy with rheumatoid arthritis of hand
What it is
This code identifies rheumatoid arthritis affecting the hand with associated polyneuropathy. It indicates a documented link between the inflammatory arthritis and nerve involvement.
Clinical signs
Typical findings include hand joint pain, swelling, stiffness, and signs of peripheral nerve dysfunction such as numbness, tingling, or weakness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the hand and states that polyneuropathy is present and related. You should also use it when the record clearly links the neuropathy to the rheumatoid condition.
Do not assume the relationship from symptoms alone. If the documentation does not specify rheumatoid polyneuropathy, check documentation before coding.
Do not use for
Do not use this code for rheumatoid arthritis without neuropathy, or for neuropathy with no documented rheumatoid link. Check documentation.
Coding tip
Verify both the hand involvement and the causal connection to rheumatoid arthritis before assigning M05.54.
