ICD-10 Code M05.252 – Rheumatoid vasculitis with rheumatoid arthritis of left hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.252 – Rheumatoid vasculitis with rheumatoid arthritis of left hip
What it is
This code identifies rheumatoid arthritis affecting the left hip, with associated rheumatoid vasculitis. Use it when the record links both the joint disease and vasculitic involvement.
Clinical signs
Findings may include chronic inflammatory hip pain, stiffness, and reduced range of motion, along with signs of systemic vasculitis. Clinical features vary; refer to documentation.
When to use this code
Use M05.252 when the provider documents rheumatoid vasculitis and specifies rheumatoid arthritis in the left hip. The diagnosis should clearly connect the vasculitis to the rheumatoid arthritis. If laterality or the vasculitic association is not documented, check documentation.
Do not use for
Do not use this code for rheumatoid arthritis of the left hip without vasculitis, or for vasculitis not linked to rheumatoid arthritis. Do not assume laterality if the note does not specify it.
Coding tip
Verify both the rheumatoid vasculitis and left hip involvement are documented before assigning M05.252.
