With all of the changes in pain medicine management, our practice will start billing for the urine drug screens (80305). CMS does not currently pay for this so we are considering having the patient's sign an ABN form to cover the cost of the cup. Is anyone in the same situation? The LCD is vague on CPT code 80305, we interpreted it to mean that it is reasonable and necessary but CMS allows $0.00 on their fee schedule. Are we able to charge the patient with an ABN form if CMS considers it reasonable and necessary?
