ICD-10 Code M05.519 – Rheumatoid polyneuropathy with rheumatoid arthritis of unspecified shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.519 – Rheumatoid polyneuropathy with rheumatoid arthritis of unspecified shoulder
What it is
This code describes rheumatoid arthritis affecting an unspecified shoulder, with associated rheumatoid polyneuropathy. Use it when the record links both the joint disease and nerve involvement to rheumatoid arthritis.
Clinical signs
Findings may include shoulder pain, stiffness, swelling, and reduced range of motion, along with peripheral 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 involving a shoulder and specifically notes rheumatoid polyneuropathy. It is appropriate when the shoulder side is not stated. If documentation names a different shoulder site or does not confirm neuropathy, check documentation.
Do not use for
Do not use this code for rheumatoid arthritis without documented polyneuropathy, or for neuropathy unrelated to rheumatoid disease. Do not assume shoulder laterality if the record identifies a specific shoulder code.
Coding tip
Verify that both the neuropathy and the unspecified shoulder involvement are explicitly documented before assigning M05.519.
