Dr. Mehmet Oz, the head of the Center for Medicare and Medicaid Services, wrote Tuesday in a post on X, "many" seniors would see lower premiums for drug coverage. But, a Trump administration official told the Wall Street Journal that only about a quarter of enrollees would see their premiums remain flat or lower. Dr. Oz said the Biden-era program amounted to an unnecessary government lifeline that benefited private health insurers. He added that "every Medicare beneficiary" will keep access to affordable plans as the Trump administration continues efforts to expand Medicare coverage to include weight-loss drugs.
