ICD-10 Code M05.52 – Rheumatoid polyneuropathy with rheumatoid arthritis of elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.52 – Rheumatoid polyneuropathy with rheumatoid arthritis of elbow
What it is
This code identifies rheumatoid arthritis affecting the elbow with associated polyneuropathy. Use it when documentation links the elbow arthritis and nerve involvement to the same rheumatoid condition.
Clinical signs
Findings may include elbow pain, swelling, stiffness, and reduced range of motion, along with peripheral nerve symptoms such as numbness, tingling, or weakness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states rheumatoid arthritis of the elbow and rheumatoid polyneuropathy together. It is appropriate when the provider documents the neuropathy as part of the rheumatoid disease process.
Code it from the clinical note, problem list, or assessment if both conditions are linked. Check documentation if the neuropathy cause is unclear or if the elbow involvement is not specified.
Do not use for
Do not use this code for elbow arthritis without rheumatoid disease, or for neuropathy with no documented rheumatoid connection. Check documentation for other causes of nerve symptoms.
Coding tip
Verify that the elbow site and polyneuropathy are both documented as rheumatoid-related before assigning M05.52.
