Preventing Medicare Telefraud Act This bill establishes conditions for payment of certain telehealth services, laboratory tests, and durable medical equipment under Medicare after the end of the COVID-19 public health emergency. Specifically, after the emergency ends, the bill conditions payment for certain high-cost laboratory tests and durable medical equipment that are ordered via telehealth on at least one in-person visit during the preceding six-month period. Additionally, practitioners must submit claims for separately billable telehealth services under the practitioner's unique national provider identification number.
