ICD-10 Code M05.511 – Rheumatoid polyneuropathy with rheumatoid arthritis of right shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.511 – Rheumatoid polyneuropathy with rheumatoid arthritis of right shoulder
What it is
This code identifies rheumatoid arthritis affecting the right shoulder with associated rheumatoid polyneuropathy. Use it when the record links both the joint disease and the nerve involvement to rheumatoid arthritis.
Clinical signs
Typical findings include inflammatory shoulder pain, stiffness, swelling, and reduced range of motion, along with neuropathic symptoms 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 of the right shoulder and specifies rheumatoid polyneuropathy. The diagnosis should clearly connect the neuropathy to rheumatoid disease, not another cause. Check documentation if laterality or the neurologic relationship is unclear.
Do not use for
Do not use it for rheumatoid arthritis without documented neuropathy, or for neuropathy from diabetes, entrapment, trauma, or other non-rheumatoid causes. Do not assume right shoulder involvement unless stated.
Coding tip
Confirm both the rheumatoid arthritis site and the neuropathy relationship in the provider note before assigning M05.511.
