ICD-10 Code M05.552 – Rheumatoid polyneuropathy with rheumatoid arthritis of left hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.552 – Rheumatoid polyneuropathy with rheumatoid arthritis of left hip
What it is
This code identifies rheumatoid arthritis affecting the left hip, with associated rheumatoid polyneuropathy. Use it when the record documents both the joint disease and nerve involvement linked to rheumatoid arthritis.
Clinical signs
Expect inflammatory joint pain, stiffness, and reduced hip motion, along with neuropathic findings such as numbness, tingling, or weakness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider specifically documents rheumatoid arthritis of the left hip and rheumatoid polyneuropathy in the same patient. It is appropriate when the neuropathy is described as related to rheumatoid disease, not another cause. Check documentation if laterality or the nerve complication is unclear.
Do not use for
Do not use this code for left hip pain alone, unspecified rheumatoid arthritis, or neuropathy from diabetes, alcohol, or other non-rheumatoid causes. Do not assume polyneuropathy without explicit documentation.
Coding tip
Confirm both the rheumatoid arthritis site and the neuropathy relationship in the chart before assigning M05.552.
