Right now we do not bill anything for blood collection for labs when that blood is drawn from a port. I work in Oncology and Hematology and we have a lab onsite. When patients come in for lab work only (no office visit or treatment of any kind) and we draw the blood from the port, is there anything we can bill for the blood draw and/or the port flush? I know we cannot bill the 96523 with labs. Thank you for your responses.
