ICD-10 Code M05.23 – Rheumatoid vasculitis with rheumatoid arthritis of wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.23 – Rheumatoid vasculitis with rheumatoid arthritis of wrist
What it is
This code identifies rheumatoid arthritis of the wrist with associated rheumatoid vasculitis. Use it when the record shows both inflammatory joint disease and vasculitic involvement linked to rheumatoid arthritis.
Clinical signs
Findings may include chronic wrist pain, swelling, stiffness, and reduced range of motion, along with signs of vasculitis such as skin lesions or other ischemic changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatoid vasculitis affecting a wrist with rheumatoid arthritis at that site. It is appropriate when the wrist is specifically identified and the vasculitic component is clearly linked to rheumatoid disease. Check documentation if laterality or site detail is unclear.
Do not use for
Do not use this code for rheumatoid arthritis of the wrist without vasculitis, or for vasculitis from another cause. If the record does not clearly link the vasculitis to rheumatoid arthritis, check documentation.
Coding tip
Confirm both the rheumatoid vasculitis diagnosis and the wrist site in the provider note before assigning M05.23.
