Yes, Medicare typically pays for CT Scans, in addition to X-rays, MRIs,and EKGs. Depending on where you have the CT Scan, Medicare Part A or Medicare Part B may cover it.

The types of CT scans that are covered include portable CT, CT angiography and CT-guided procedures.

Other non-laboratory diagnostic screenings are also covered by Medicare Part B, though some out-of-pocket costs may apply.

What is the Medicare-Approved Amount for a CT Scan?

Your cost for CT scans performed in a doctor's office or in an independent testing facility will likely be a 20 percent coinsurance of the Medicare-approved amount. For scans done in a hospital outpatient setting, you'll be charged a copayment for the costs that Medicare covers.

Medicare Part B covers certain diagnostic tests that your health care provider deems necessary to advance a diagnosis or rule out a suspected illness or condition. These include CT scans.

Other such imaging services and diagnostic tests include X-rays, MRIs, PET scans and EKGs. Medicare will also cover certain preventive health care services.
