If the provider performs the service before Dec. 31, 2018, then you will apply code 71020 (Radiologic examination, chest, 2 views, frontal and lateral). If the provider performs the service from Jan. 1, 2018 and beyond, you will apply code 71046 (Radiologic examination, chest; 2 views). Next, you will want to apply the transportation code. You will apply code R0070 (Transportation of portable X-ray equipment and personnel to home or nursing home, per trip to facility or location, one patient seen) when the personnel see one patient and R0075 (Transportation of portable X-ray equipment and personnel to home or nursing home, per trip to facility or location, more than one patient seen) to report imaging multiple patients at the same location. Finally, if you are reporting R0075, you will want to include a modifier to identify the number of patients seen by the provider. You will include one of the following modifiers: Things to consider: According to The Centers for Medicare & Medicaid Services (CMS), the following services are eligible for portable X-ray coverage:
