ICD-10 Code M05.25 – Rheumatoid vasculitis with rheumatoid arthritis of hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.25 – Rheumatoid vasculitis with rheumatoid arthritis of hip
What it is
This code identifies rheumatoid vasculitis occurring with rheumatoid arthritis and involving the hip. Use it when the record clearly links vasculitic disease to rheumatoid arthritis at that joint.
Clinical signs
Clinical features vary; refer to documentation. You may see rheumatoid arthritis with evidence of vasculitis and hip involvement, such as pain, stiffness, or impaired joint function noted by the clinician.
When to use this code
Use this code when the provider documents rheumatoid vasculitis and specifies the hip as the affected site. It applies when the diagnosis is not just rheumatoid arthritis of the hip, but rheumatoid vasculitis with that joint involvement.
Code only from explicit documentation. If the record mentions vasculitis without a rheumatoid link, or hip arthritis without vasculitis, this code is not supported.
Do not use for
Do not use this code for rheumatoid arthritis of the hip without vasculitis. Do not assume vasculitis is present unless the provider states it clearly.
Coding tip
Verify both elements in the note: rheumatoid vasculitis and hip involvement; if either is missing, check documentation.
