I was told by another Radiation Oncologist that if your practice is in an underserved area, that the provider can bill for a portion of the technical as well as the professional portion. I know that you can bill with the AQ modifier for HPSA to Medicare and get a 10% bonus payment, but he states that this is different. Does anyone have any insight on this matter? If so how would you bill it to the insurance, is there a modifier etc?
