ICD-10 Code M05.351 – Rheumatoid heart disease with rheumatoid arthritis of right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.351 – Rheumatoid heart disease with rheumatoid arthritis of right hip
What it is
This code identifies rheumatoid arthritis affecting the right hip together with rheumatoid heart disease. Use it when documentation links both conditions as part of the same rheumatoid disease process.
Clinical signs
Clinical features may include inflammatory joint pain, stiffness, reduced hip motion, and documented cardiac involvement related to rheumatoid disease. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider explicitly documents rheumatoid heart disease and rheumatoid arthritis in the right hip. It is appropriate when both diagnoses are confirmed and connected in the medical record.
If the chart mentions only hip arthritis or only cardiac involvement, you should not assume this combination. Check documentation for laterality and the specific rheumatoid relationship before assigning the code.
Do not use for
Do not use this code for rheumatoid arthritis of another joint, unspecified hip laterality, or heart disease not documented as rheumatoid. Check documentation.
Coding tip
Verify both the right-hip site and the rheumatoid heart disease linkage in the provider note before coding.
