ICD-10 Code M05.341 – Rheumatoid heart disease with rheumatoid arthritis of right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.341 – Rheumatoid heart disease with rheumatoid arthritis of right hand
What it is
This code identifies rheumatoid heart disease occurring with rheumatoid arthritis affecting the right hand. Use it when the record links both the cardiac manifestation and the right-hand rheumatoid arthritis.
Clinical signs
Clinical features vary; refer to documentation. Records may note rheumatoid arthritis in the right hand with cardiac involvement described as rheumatoid heart disease, often based on established rheumatologic and cardiac findings.
When to use this code
Use this code when the provider documents rheumatoid heart disease and specifically states rheumatoid arthritis of the right hand. It is appropriate when the hand laterality is clear and both conditions are part of the same diagnosis statement. Check documentation if the heart disease is suspected but not confirmed.
Do not use for
Do not use this code if rheumatoid heart disease is not documented or if the arthritis site is not the right hand. Do not assign it for nonspecific rheumatoid arthritis without the cardiac manifestation.
Coding tip
Verify both the cardiac diagnosis and right-hand laterality in the provider note before coding.
