Blood Flow Check of a Dialysis Access

North Carolina rates for HCPCS 90940

Measures how much blood is flowing through the surgically created connection used for dialysis, by introducing a harmless indicator into the circuit during a dialysis session and timing how it travels. A falling flow warns that the access is narrowing and may clot off, so it can be treated before it fails altogether. It uses the needles already in place for the dialysis session, so nothing extra is inserted.
