ICD-10 Code M05.311 – Rheumatoid heart disease with rheumatoid arthritis of right shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.311 – Rheumatoid heart disease with rheumatoid arthritis of right shoulder
What it is
This code identifies rheumatoid arthritis affecting the right shoulder in a patient who also has rheumatoid heart disease. It links the joint disease and the cardiac manifestation to the same rheumatoid condition.
Clinical signs
Expect right shoulder pain, stiffness, swelling, and reduced range of motion consistent with rheumatoid arthritis. Clinical features vary; refer to documentation for evidence of rheumatoid heart disease.
When to use this code
Use this code when the record clearly documents rheumatoid heart disease and rheumatoid arthritis involving the right shoulder. The provider should connect both conditions to rheumatoid disease. If the side or cardiac involvement is not specified, check documentation.
Do not use for
Do not use it for rheumatoid arthritis of the shoulder without documented right-sided involvement. Do not assign it if rheumatoid heart disease is not documented or if another shoulder is specified.
Coding tip
Verify both the cardiac diagnosis and the right shoulder laterality before coding.
