Medicare Prescription Drug Donut Hole
This term pertains to Medicare prescription drugs.
Most plans with Medicare prescription drug coverage (Part D) have a coverage gap called a "donut hole."
This means that after you and your drug plan have spent a certain amount of money for covered drugs, you have to pay all costs out-of-pocket for your prescriptions up to a yearly limit.
Once you have spent up to the yearly limit, your coverage gap ends and your drug plan helps pay for covered drugs again.
