ICD-10 Code M05.332 – Rheumatoid heart disease with rheumatoid arthritis of left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.332 – Rheumatoid heart disease with rheumatoid arthritis of left wrist
What it is
This code identifies rheumatoid arthritis affecting the left wrist in a patient who also has rheumatoid heart disease. Use it when both the cardiac complication and the joint involvement are documented together.
Clinical signs
Typical findings include chronic inflammatory wrist pain, swelling, stiffness, and reduced range of motion. Rheumatoid heart disease may be documented by cardiac involvement associated with rheumatoid arthritis; clinical features vary, so refer to documentation.
When to use this code
Use this code when the record clearly states rheumatoid heart disease and rheumatoid arthritis of the left wrist in the same patient. It applies whether the wrist involvement is active or chronic, as long as the documentation supports both conditions.
If the provider specifies another joint, or if heart disease is not linked to rheumatoid arthritis, choose a different code. Check documentation when the laterality or cardiac relationship is unclear.
Do not use for
Do not use it for rheumatoid arthritis without documented heart disease, or for heart disease unrelated to rheumatoid arthritis. Do not assign it when the affected wrist is not the left wrist.
Coding tip
Verify both the rheumatoid heart disease and left-wrist laterality in the note before assigning M05.332.
