If you’ve recently received a COVID-19 test kit without requesting one, you’re probably a scam victim. Scammers seem to be working double-time before the COVID-19 public emergency officially ends on May 11 and free tests won’t be as readily available anymore. People across the country reported they’ve received COVID-19 tests without having ordered any, a common tactic for scammers who send the tests to people and then bill Medicare. Even if you don’t directly lose money for these unsolicited tests, they can alter your Medicare coverage and increase healthcare costs for everyone. “Fraudulent charges may affect your Medicare coverage,” warned the Federal Trade Commission in August. “Although the money doesn’t come directly out of your pocket, you may not be able to get medical equipment you need. “ The end is near: Biden will end COVID-19 emergency declarations on May 11 after more than 3 yearsReemerging fraud: How the system feds rely on to stop repeat health fraud is deeply flawedWhen do free COVID tests end?Free at-home COVID-19 tests will no longer be available for most people after May 11, when President Joe Biden says the COVID-19 public health emergency officially ends.

After that, they’ll be harder to get. Starting May 12, Medicare won’t fully pay for over-the-counter COVID-19 tests, and private insurers will no longer be required to cover the costs of testing. Medicaid recipients, however, will be able to receive free at-home tests through September 2024. People who won’t receive free tests anymore may be able to tap state and local organizations. For example, the North Carolina Department of Health and Human Services said residents would be able to request free, at-home COVID-19 tests and The Rockefeller Foundation will keep providing free kits to at-risk communities through June 30.
