Clearing A Blocked Dialysis Access Site

Maryland rates for HCPCS 36904

This procedure removes a blood clot that is blocking a permanent dialysis access site, such as a fistula or graft, so that dialysis can continue safely. It's done by threading thin instruments through the skin into the blood vessel, guided by live imaging, and may include injecting a clot-dissolving medication directly at the site. The goal is to restore blood flow through the access without open surgery.
