ICD-10 Code M05.241 – Rheumatoid vasculitis with rheumatoid arthritis of right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.241 – Rheumatoid vasculitis with rheumatoid arthritis of right hand
What it is
This code identifies rheumatoid arthritis of the right hand complicated by rheumatoid vasculitis. Use it when the record shows inflammatory joint disease plus vasculitic involvement tied to rheumatoid disease.
Clinical signs
Findings may include painful, swollen hand joints with evidence of vasculitis affecting small vessels. Clinical features vary; refer to documentation for the specific vascular and joint manifestations.
When to use this code
Use M05.241 when the provider documents rheumatoid vasculitis and specifies the right hand as the affected site. It is appropriate when the vasculitis is part of the rheumatoid arthritis diagnosis, not a separate unrelated vasculitis. Confirm laterality and that the hand, not another joint, is identified.
Do not use for
Do not use this code if rheumatoid vasculitis is not documented, or if the arthritis site is not the right hand. Check documentation when the record only states rheumatoid arthritis, vasculitis, or an unspecified hand.
Coding tip
Verify both the vasculitis complication and right-hand laterality in the note before assigning M05.241.
