A Texas physician pleaded guilty in connection with his role in a $5.5 million over-the-counter (OTC) COVID-19 test fraud scheme. According to court documents, Mark Mazzare MD, 57, of Tyler, purchased Medicare beneficiary identifiers (BINs) that were used to bill Medicare millions of dollars for OTC COVID-19 test kits, many of which had not been requested by the beneficiaries. Mazzare entered into a sham agreement with a purported marketer to conceal the purchase of BINs as “lead packages,” which in reality consisted of BINs and fraudulently generated audio recordings purporting to be the voices of the beneficiaries requesting the OTC COVID-19 tests. Mazzare caused OTC COVID-19 tests to be shipped to Medicare beneficiaries whose BINs had been purchased, regardless of whether the Medicare beneficiaries had requested or needed the tests. From in or around November 2022 to in or around June 2023, Mazzare caused more than $5.5 million in claims to be submitted to Medicare for OTC COVID-19 tests that were medically unnecessary and ineligible for reimbursement. Medicare paid approximately $3.44 million on those claims.
