ICD-10 Code M05.2 – Rheumatoid vasculitis with rheumatoid arthritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.2 – Rheumatoid vasculitis with rheumatoid arthritis
What it is
This code identifies rheumatoid arthritis complicated by vasculitis, meaning inflammation of blood vessels linked to the rheumatoid disease. Use it when the record clearly documents both rheumatoid arthritis and rheumatoid vasculitis.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include evidence of systemic vasculitis in a patient with rheumatoid arthritis, such as skin, nerve, or organ involvement described by the clinician.
When to use this code
Use this code when the provider documents rheumatoid vasculitis occurring with rheumatoid arthritis. It supports cases where the vasculitis is part of the rheumatoid disease process, not a separate unrelated vasculitis. If the note is unclear, check documentation before assigning the code.
Do not use for
Do not use it for rheumatoid arthritis without vasculitis. Do not use it for vasculitis that is not documented as rheumatoid in origin; check documentation.
Coding tip
Assign M05.2 only when both conditions are explicitly linked in the record.
