ICD-10 Code M05.232 – Rheumatoid vasculitis with rheumatoid arthritis of left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.232 – Rheumatoid vasculitis with rheumatoid arthritis of left wrist
What it is
This code identifies rheumatoid arthritis complicated by rheumatoid vasculitis affecting the left wrist. Use it when documentation links the vasculitis to rheumatoid arthritis and specifies the left wrist site.
Clinical signs
Clinical features vary; refer to documentation. Findings may include inflammatory wrist pain, swelling, reduced motion, and signs of vasculitic involvement such as skin or tissue changes near the affected area.
When to use this code
Use this code when the provider documents rheumatoid vasculitis with rheumatoid arthritis and clearly states the left wrist as the affected joint. It may apply in specialist notes, discharge summaries, or problem lists that confirm the relationship.
If the record mentions rheumatoid arthritis without vasculitis, or vasculitis without a documented left wrist site, you should not assign this code. Check documentation for laterality and the exact diagnostic wording.
Do not use for
Do not use it for nonspecific rheumatoid arthritis of the wrist, or for vasculitis that is not linked to rheumatoid arthritis. Check documentation when the site or cause is unclear.
Coding tip
Code only when both the rheumatoid vasculitis and the left wrist involvement are explicitly documented.
