ICD-10 Code M05.239 – Rheumatoid vasculitis with rheumatoid arthritis of unspecified wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.239 – Rheumatoid vasculitis with rheumatoid arthritis of unspecified wrist
What it is
This code identifies rheumatoid arthritis complicated by rheumatoid vasculitis, with the affected wrist not further specified. Use it when the record links vasculitic disease to rheumatoid arthritis and documents wrist involvement without laterality.
Clinical signs
Clinical features vary; refer to documentation. Rheumatoid vasculitis may present with systemic inflammation and signs of small- or medium-vessel involvement, alongside established rheumatoid arthritis and wrist symptoms or findings.
When to use this code
Use this code when the provider documents rheumatoid vasculitis in a patient with rheumatoid arthritis and identifies the wrist as involved, but does not specify right or left. It also fits when the chart notes wrist arthritis with vasculitic complications tied to RA.
If laterality is available, code to the more specific wrist code instead. Check documentation for whether the vasculitis is explicitly associated with rheumatoid arthritis, rather than another cause.
Do not use for
Do not use this code for rheumatoid arthritis of the wrist without vasculitis, or for vasculitis not linked to rheumatoid arthritis. Check documentation if the wrist side is specified or if another diagnosis better explains the findings.
Coding tip
Always verify that both rheumatoid vasculitis and unspecified wrist involvement are documented before assigning M05.239.
