ICD-10 Code M05.61 – Rheumatoid arthritis of shoulder with involvement of other organs and systems (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.61 – Rheumatoid arthritis of shoulder with involvement of other organs and systems
What it is
M05.61 identifies rheumatoid arthritis affecting the shoulder, with documented involvement of other organs or body systems. Use it when the record shows both the joint disease and extra-articular disease.
Clinical signs
Expect inflammatory shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for evidence of systemic or extra-articular involvement.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the shoulder and states that other organs or systems are involved. It may appear in assessments, problem lists, or specialist notes. Check documentation for the specific shoulder side and any recorded systemic manifestations.
Do not use for
Do not use this code for rheumatoid arthritis without shoulder involvement, or when extra-articular disease is not documented. Do not assign it for nonspecific shoulder pain or other inflammatory arthropathies.
Coding tip
Verify that both the shoulder site and the systemic involvement are explicitly documented before coding M05.61.
