ICD-10 Code M05.29 – Rheumatoid Vasculitis with Rheumatoid Arthritis of Multiple Sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.29 – Rheumatoid vasculitis with rheumatoid arthritis of multiple sites
What it is
M05.29 identifies rheumatoid arthritis complicated by rheumatoid vasculitis affecting multiple sites. Use it when the record shows both established rheumatoid arthritis and vasculitic involvement linked to that disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include systemic vasculitic manifestations, such as skin, nerve, or organ involvement, occurring in a patient with rheumatoid arthritis.
When to use this code
Use this code when the provider clearly documents rheumatoid vasculitis with rheumatoid arthritis and specifies involvement of multiple sites. It is appropriate when the condition is described as a rheumatoid complication rather than a separate primary vasculitis. Check documentation if the site details are unclear.
Do not use for
Do not use this code for rheumatoid arthritis without vasculitis, or for vasculitis not linked to rheumatoid arthritis. If the chart does not confirm multiple-site involvement, check documentation.
Coding tip
Code only when the linkage between rheumatoid arthritis and vasculitis is explicit in the record.
