ICD-10 Code M05.222 – Rheumatoid Vasculitis with Rheumatoid Arthritis of Left Elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.222 – Rheumatoid vasculitis with rheumatoid arthritis of left elbow
What it is
M05.222 identifies rheumatoid vasculitis occurring with rheumatoid arthritis in the left elbow. Use it when the record shows both rheumatoid arthritis and vasculitic involvement affecting that joint.
Clinical signs
Clinical features may include inflammatory elbow pain, swelling, stiffness, and signs of vasculitis such as skin changes or ischemic findings. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatoid vasculitis and specifies the left elbow as the affected site. It applies when the condition is active and linked to rheumatoid arthritis, not when vasculitis is only suspected. Check documentation if laterality or the vasculitic component is unclear.
Do not use for
Do not use this code for rheumatoid arthritis of the left elbow without vasculitis, or for vasculitis affecting another site. Do not assign it if the record does not clearly state rheumatoid vasculitis.
Coding tip
Verify both the vasculitis diagnosis and left-sided elbow involvement before coding.
