ICD-10 Code M05.269 – Rheumatoid vasculitis with rheumatoid arthritis of unspecified knee (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.269 – Rheumatoid vasculitis with rheumatoid arthritis of unspecified knee
What it is
This code identifies rheumatoid arthritis complicated by rheumatoid vasculitis, with the affected knee not further specified as right or left. Use it when the record clearly links vasculitis to rheumatoid arthritis and names the knee joint.
Clinical signs
Findings may include established rheumatoid arthritis plus evidence of vasculitic involvement, such as skin lesions, neuropathy, or ischemic changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatoid vasculitis in a patient with rheumatoid arthritis and specifies the knee as involved, but does not identify laterality. It is appropriate for encounters focused on the joint manifestation or systemic complication. Check documentation if the record is unclear.
Do not use for
Do not use this code for rheumatoid arthritis without vasculitis, or for vasculitis unrelated to rheumatoid disease. If the knee side is documented, choose the laterality-specific code instead.
Coding tip
Confirm both the rheumatoid vasculitis diagnosis and the unspecified knee designation before assigning M05.269.
