Trump’s executive order halts an effort to cap the copayment for generic medications at $2 for Medicare beneficiaries.

The rescinded order directed Medicare and Medicaid to test ways to lower drug costs for enrollees. Those tests hadn’t started, so current drug prices are unaffected.

One of those now-cancelled policies directed Medicare to investigate ways to slash drug costs, including the possibility of a $2 monthly out-of-pocket cap on some generic medications. Monday's actions also follow through on a key goal of Trump's first term -- weakening the Affordable Care Act.
