Starting in 2025 and continuing through 2026, the Medicare Part D “Donut Hole” (the coverage gap) has effectively been eliminated due to the Inflation Reduction Act.
Here is a brief breakdown of the structural changes and the new out-of-pocket caps.
Key Changes for 2026
- The $2,000 Cap: The most significant change is the permanent $2,000 annual out-of-pocket cap on covered prescription drugs. Once you spend $2,000 on Part D drugs in 2026, you will have $0 cost-sharing for the remainder of the year.
- Elimination of the Donut Hole: Previously, beneficiaries entered a “coverage gap” where they were responsible for a larger percentage of drug costs. This phase is gone. The payment structure is now simplified into three stages: the Deductible, Initial Coverage, and Catastrophic Coverage (which now begins immediately after hitting the $2,000 limit).
- Medicare Prescription Payment Plan: You have the option to pay out-of-pocket costs in monthly installments rather than all at once at the pharmacy. This “smoothing” option helps manage the $2,000 total over the full calendar year.
- Manufacturer Discounts: Pharmaceutical companies are now required to provide discounts on brand-name drugs starting in the initial coverage phase, which helps keep the beneficiary’s progress toward the $2,000 cap more predictable.
Summary of the 2026 Benefit Design
- Deductible: You pay 100% until the limit (approx. $590 in 2026, subject to final CMS confirmation) is met.
- Initial Coverage: You pay 25% coinsurance for covered drugs.
- Catastrophic Coverage: Once your out-of-pocket spending reaches $2,000, you pay $0 for all covered Part D drugs for the rest of the year.
