Blood Draw From An Existing Catheter

Maryland rates for HCPCS 36592

Collection of a blood sample drawn back through a catheter that is already in place in a vein, rather than by a fresh needle stick. It covers the nursing time and supplies used to withdraw, discard and flush appropriately so the sample is not diluted. It is used for patients who have a long-term line and need frequent testing.
