ICD-10 Code M05.251 – Rheumatoid vasculitis with rheumatoid arthritis of right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.251 – Rheumatoid vasculitis with rheumatoid arthritis of right hip
What it is
This code identifies rheumatoid arthritis affecting the right hip, with associated rheumatoid vasculitis. Use it when the record documents both the inflammatory joint disease and vasculitic involvement.
Clinical signs
Findings may include chronic inflammatory arthritis in the right hip plus evidence of vasculitis, such as skin, nerve, or organ involvement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider clearly links rheumatoid vasculitis to rheumatoid arthritis and specifies the right hip as the affected joint. It is appropriate for confirmed diagnoses in outpatient, inpatient, or specialty notes. Check documentation if laterality or vasculitis is not stated.
Do not use for
Do not use it for rheumatoid arthritis of the hip without vasculitis, or for vasculitis not documented as rheumatoid. If the side is not right or the condition is uncertain, check documentation.
Coding tip
Verify both components—rheumatoid vasculitis and right hip involvement—before assigning M05.251.
