Does anyone know if you can bill a Medicare patient, or any patient, for an FOBT (hemoccult test) if they don't bring it back. I know you cannot bill the insurance for the test if you didn't do the test. Right now we are finding a lot of patient's have not brought their FOBT back that we gave them a while back. These patient's have been called and reminded to bring the test back. These are now expired kits. We have taken a loss on these kits and would like to charge the patient, at the least, our cost but i don't know the guidelines for doing so. Any suggestions?
