What Replaces the Medicare Donut Hole?

Medicare Part D, the prescription drug coverage component, has undergone significant changes. Historically, many individuals encountered a “coverage gap,” often called the “donut hole,” which temporarily increased out-of-pocket costs after initial coverage limits were met. Beginning in 2025, the Inflation Reduction Act eliminates this gap, simplifying Part D and introducing a new annual out-of-pocket cap. Understanding these updated phases is important for managing prescription drug expenses.

Understanding Medicare Part D Coverage Stages

Beginning in 2025, Medicare Part D coverage is streamlined into three distinct stages, dictating how drug costs are shared between the beneficiary, the plan, and other entities. This provides more predictable costs for beneficiaries.

The first phase is the deductible period. Beneficiaries are responsible for 100% of their prescription drug costs up to a certain amount. For 2025, the standard deductible is $590, though some plans may offer a lower or zero-dollar deductible. Once this deductible is met, beneficiaries transition to the next stage of coverage.

Following the deductible, the initial coverage phase begins. Here, costs for covered drugs are shared. Beneficiaries pay 25% of their drug costs, the Part D plan covers 65%, and manufacturers contribute an additional 10% discount for brand-name drugs.

This phase continues until a beneficiary’s total out-of-pocket spending for covered drugs reaches $2,000 for the year. This $2,000 threshold is the new limit before entering the catastrophic coverage phase. The coverage gap is eliminated, meaning there is no longer a temporary reduction in coverage.

The final phase is catastrophic coverage, providing substantial financial protection for individuals with high prescription drug costs. Once annual out-of-pocket spending reaches $2,000, beneficiaries pay nothing for covered medications for the remainder of the calendar year. The Part D plan pays 60% of drug costs, drug manufacturers contribute 20%, and Medicare covers the remaining 20%.

Counting Towards Catastrophic Coverage

True Out-of-Pocket (TrOOP) costs determine when a beneficiary reaches the catastrophic coverage phase. TrOOP represents the total amount a Medicare beneficiary pays for covered prescription drugs before reaching the yearly out-of-pocket cap.

Costs contributing to TrOOP include the annual deductible paid by the beneficiary, and any copayments or coinsurance paid during the initial coverage phase. Manufacturer discounts on brand-name drugs also count towards TrOOP, even if the beneficiary does not directly pay this portion. Payments from assistance programs, such as Medicare’s Extra Help (Low-Income Subsidy) or State Pharmaceutical Assistance Programs (SPAPs), also contribute.

Not all prescription drug expenses count towards TrOOP. Monthly Part D plan premiums do not contribute. Costs for drugs not covered by the plan’s formulary are excluded. The portion of drug costs paid by the Part D plan itself, during either the initial coverage or catastrophic phases, also does not count. The $2,000 out-of-pocket cap is the TrOOP threshold for entering catastrophic coverage.

Managing Prescription Drug Costs Under Medicare Part D

While the elimination of the coverage gap simplifies Medicare Part D, beneficiaries can still employ strategies to manage their prescription drug expenses effectively. Proactive planning and awareness of available resources can help reduce overall costs.

An annual review of Part D plans during the Open Enrollment period is a beneficial practice. Comparing plans based on their premiums, deductibles, and formulary coverage for specific medications can help identify the most cost-effective option for individual needs. Plans with lower or zero deductibles, for example, might be advantageous for those with predictable, ongoing prescription needs.

Discussing generic drug alternatives with a doctor or pharmacist can lead to significant savings. Generic medications typically have lower costs than their brand-name counterparts while offering comparable efficacy. Choosing generics whenever appropriate can help keep out-of-pocket spending lower.

For individuals with limited income and resources, Medicare’s Extra Help program, also known as the Low-Income Subsidy (LIS), can provide substantial financial assistance. This program helps cover Part D premiums, deductibles, and copayments, and can significantly reduce the overall cost burden. Eligibility for Extra Help is determined by income and resource limits, which are updated annually.

Exploring patient assistance programs (PAPs) offered by pharmaceutical companies or non-profit organizations can also provide support for high-cost medications. These programs may offer free or reduced-cost drugs to eligible individuals. Consulting with a healthcare provider about such programs can uncover potential savings.

Beginning in 2025, a new Medicare Prescription Payment Plan (M3P) allows beneficiaries to spread their out-of-pocket drug costs over the calendar year through monthly payments. This voluntary option offers greater financial flexibility by eliminating the need to pay large upfront sums at the pharmacy.
