ICD-10 Code M05.611 – Rheumatoid arthritis of right shoulder with involvement of other organs and systems (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.611 – Rheumatoid arthritis of right shoulder with involvement of other organs and systems
What it is
This code identifies rheumatoid arthritis affecting the right shoulder with systemic involvement. Use it when the record shows rheumatoid disease in that joint plus involvement of other organs or systems.
Clinical signs
Typical findings include inflammatory joint pain, stiffness, swelling, and reduced shoulder motion. Clinical features vary; refer to documentation for evidence of rheumatoid involvement beyond the joint.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the right shoulder and also notes extra-articular or systemic involvement. It applies when the right shoulder is specifically identified as the affected joint. Check documentation if the record does not clearly link the systemic disease to the rheumatoid arthritis.
Do not use for
Do not use this code for rheumatoid arthritis limited to the shoulder without other organ or system involvement. Do not use it when the laterality is not right or when another joint is the documented site.
Coding tip
Verify both laterality and systemic involvement in the provider note before assigning M05.611.
