ICD-10 Code M05.352 – Rheumatoid Heart Disease with Rheumatoid Arthritis of Left Hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.352 – Rheumatoid heart disease with rheumatoid arthritis of left hip
What it is
This code identifies rheumatoid heart disease occurring with rheumatoid arthritis affecting the left hip. Use it when the record documents both cardiac involvement from rheumatoid disease and left-hip rheumatoid arthritis.
Clinical signs
Clinical features vary; refer to documentation. Records may note inflammatory joint pain, stiffness, reduced hip motion, and evidence of rheumatoid cardiac involvement such as valvular or pericardial disease.
When to use this code
Use this code when the provider clearly links rheumatoid heart disease with rheumatoid arthritis of the left hip. The diagnosis should be documented as current, not merely historical. If the heart condition or hip involvement is unspecified, check documentation before assigning this code.
Do not use for
Do not use it if rheumatoid heart disease is absent or if the hip arthritis is on the right side or unspecified. Do not assume cardiac involvement from rheumatoid arthritis alone.
Coding tip
Verify both the heart disease and the left-hip laterality in the same note before coding.
