2026 ICD-10-CM Diagnosis Code M05.24 – Rheumatoid vasculitis with rheumatoid arthritis of hand
What it is
This code identifies rheumatoid vasculitis affecting the hand in a patient with rheumatoid arthritis. It indicates inflammatory blood vessel involvement linked to rheumatoid disease.
Clinical signs
Clinical features vary; refer to documentation. Findings may include skin or tissue changes in the hand consistent with vasculitis, along with documented rheumatoid arthritis involvement.
When to use this code
Use this code when the provider documents rheumatoid vasculitis and specifies the hand as the involved site. The record should also support rheumatoid arthritis as the underlying condition. If the site or vasculitis relationship is unclear, check documentation before coding.
Do not use for
Do not use this code for rheumatoid arthritis of the hand without vasculitis. It is also inappropriate when vasculitis is documented in another site or when the diagnosis is uncertain.
Coding tip
Confirm both the vasculitis diagnosis and the hand location in the provider note before assigning M05.24.
