ICD-10 Code M05.319 – Rheumatoid heart disease with rheumatoid arthritis of unspecified shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.319 – Rheumatoid heart disease with rheumatoid arthritis of unspecified shoulder
What it is
This code identifies rheumatoid heart disease occurring with rheumatoid arthritis affecting the unspecified shoulder. Use it when the record documents both the cardiac involvement and shoulder rheumatoid arthritis, but the shoulder side is not stated.
Clinical signs
Findings may include established rheumatoid arthritis plus documented heart involvement attributed to rheumatoid disease. Clinical features vary; refer to documentation for the specific cardiac manifestations and whether the shoulder involvement is active or historical.
When to use this code
Use M05.319 when the provider clearly links rheumatoid heart disease to rheumatoid arthritis and also documents rheumatoid arthritis of an unspecified shoulder. This code is appropriate for outpatient, inpatient, or problem-list documentation when both conditions are stated together.
If the record names only the heart disease or only shoulder arthritis, choose a more specific code for the documented condition. Check documentation when laterality, cardiac detail, or the rheumatoid connection is unclear.
Do not use for
Do not use this code if the shoulder side is documented; select the correct laterality instead. Do not use it for heart disease not attributed to rheumatoid arthritis, or for shoulder pain without documented rheumatoid arthritis.
Coding tip
Confirm both the rheumatoid heart disease and the unspecified shoulder involvement are explicitly documented before assigning M05.319.
