Understanding PET Scans

Positron Emission Tomography (PET) scans are advanced diagnostic imaging tests that use radioactive substances to produce detailed images of internal organs and tissues. These scans are primarily used to detect and monitor various medical conditions, including cancer, heart disease, and neurological disorders. PET scans provide valuable information about the functioning of organs and tissues at a cellular level, aiding in accurate diagnoses and treatment planning.

Does Medicare Cover PET Scans?

Medicare, the federal health insurance program for individuals aged 65 and older, as well as certain younger individuals with disabilities, generally covers medically necessary PET scans. However, specific coverage criteria and guidelines apply. Let’s explore the key factors that determine Medicare coverage for PET scans:

Medicare Part B Coverage

Medicare Part B, also known as Medical Insurance, typically covers outpatient services, including diagnostic tests like PET scans. To be eligible for coverage, the PET scan must be ordered by a Medicare-approved healthcare provider who accepts the assignment.

Medical Necessity

Medicare requires that PET scans be deemed medically necessary for coverage to apply. This means that the scan should be necessary to diagnose or treat a specific medical condition. The healthcare provider must provide supporting documentation, outlining the medical necessity of the PET scan.
