ICD-10 Code M05.551 – Rheumatoid polyneuropathy with rheumatoid arthritis of right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.551 – Rheumatoid polyneuropathy with rheumatoid arthritis of right hip
What it is
This code identifies rheumatoid arthritis affecting the right hip with associated rheumatoid polyneuropathy. Use it when the record shows both the joint disease and nerve involvement linked to rheumatoid disease.
Clinical signs
Typical findings include inflammatory hip pain, stiffness, 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 clinician documents rheumatoid arthritis in the right hip and separately confirms rheumatoid polyneuropathy. It fits cases where nerve symptoms are attributed to rheumatoid disease, not another cause. Check documentation if laterality or neuropathy linkage is unclear.
Do not use for
Do not use it for rheumatoid arthritis without documented polyneuropathy, or for neuropathy caused by diabetes, alcohol, or another condition. Do not assume right hip involvement if the record does not specify it.
Coding tip
Verify both the rheumatoid polyneuropathy and the right hip laterality in the provider note before assigning M05.551.
