ICD-10 Code M05.71 – Rheumatoid arthritis with rheumatoid factor of shoulder without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.71 – Rheumatoid arthritis with rheumatoid factor of shoulder without organ or systems involvement
What it is
This code identifies rheumatoid arthritis affecting the shoulder joint with a positive rheumatoid factor and no documented organ or system involvement. Use it when the record specifically links RA to the shoulder.
Clinical signs
Typical findings include chronic inflammatory shoulder pain, stiffness, swelling, and reduced range of motion. Clinical features vary; refer to documentation for rheumatoid factor positivity and joint involvement.
When to use this code
Use this code when the provider documents rheumatoid arthritis with rheumatoid factor involving the shoulder only. It also fits when the note states no extra-articular or systemic involvement. Verify laterality and any additional joint sites before coding.
Do not use for
Do not use it for shoulder pain without a documented rheumatoid arthritis diagnosis. Do not assign it if the record shows systemic involvement, another joint site only, or documentation is unclear; check documentation.
Coding tip
Confirm that rheumatoid factor positivity and shoulder involvement are both documented before assigning M05.71.
