What is the Medicare donut hole (coverage gap)?

The Medicare Part D “donut hole,” which existed from 2006 (when the Medicare Part D began) through 2024, referred to the coverage gap in the Part D prescription drug benefit. This gap existed after an enrollee’s prescription drug costs exceeded the initial coverage limit (an amount set each year by CMS), but had not yet reached the catastrophic coverage level.

The donut hole no longer exists as of 2025, due to the Inflation Reduction Act. Instead, Medicare Part D now just has three phases: The deductible phase, the initial coverage phase, and the catastrophic coverage phase.

Learn more about how Part D coverage works now that the “donut hole” has been eliminated.
