The End of the Infamous Part D “Donut Hole”
For years, the Medicare Part D coverage gap—widely known as the 'donut hole'—was a major source of financial anxiety for seniors. This was a phase in your prescription drug plan where, after reaching a certain spending limit, you would temporarily pay a much higher percentage of your medication costs. Fortunately, thanks to reforms from the Inflation Reduction Act, this is no longer a concern. As of January 1, 2025, the donut hole was officially eliminated.
How the Old Part D Coverage Gap Worked
To fully appreciate the change, it's helpful to understand the old system. In 2024, the last year with the traditional donut hole, there were four distinct phases:
- Deductible: You paid 100% of your drug costs until you met your plan's deductible.
- Initial Coverage: After the deductible, your plan covered most costs, and you paid a copay or coinsurance. In 2024, this phase ended when total drug costs reached $5,030.
- Coverage Gap ('Donut Hole'): Once total costs hit the limit, you entered the donut hole. In 2024, you paid 25% of the cost for covered brand-name and generic drugs.
- Catastrophic Coverage: When your out-of-pocket spending reached a certain limit ($8,000 in 2024), you exited the donut hole and paid minimal costs for the rest of the year.
The New 2025 Part D Prescription Drug Program
As of 2025, the Part D coverage structure is simplified and offers much better protection against high out-of-pocket costs. The catastrophic phase was completely reformed, providing a fixed annual spending cap. Here’s the new structure:
- Deductible: You pay 100% of your drug costs until your deductible is met.
- Initial Coverage: You pay a standard copay or coinsurance, and your plan pays the rest.
- Catastrophic Coverage: Once your out-of-pocket spending hits a specific annual limit ($2,000 in 2025), you enter the catastrophic phase. The biggest difference? You pay nothing for covered Part D drugs for the remainder of the year.
Unveiling the Other Major Gaps in Medicare
While the elimination of the donut hole is a significant improvement, many beneficiaries are surprised to learn that Original Medicare (Parts A and B) has several other substantial coverage gaps. These are the out-of-pocket costs and uncovered services that can still leave seniors financially vulnerable.
1. High Cost-Sharing Requirements
Original Medicare is not free. It includes significant deductibles, copayments, and coinsurance that you must pay out-of-pocket. For example:
- Part A Deductible: This is a deductible you must pay for each hospital stay. It is not an annual deductible.
- Part A Coinsurance: For extended hospital or skilled nursing facility stays, you are responsible for daily coinsurance charges.
- Part B Deductible: You pay an annual deductible for Part B services.
- Part B Coinsurance: After your deductible is met, you are typically responsible for 20% of the Medicare-approved amount for most doctor's services and outpatient care.
2. Services Not Covered by Original Medicare
Original Medicare was not designed to cover every possible health need. The most common uncovered services represent significant gaps for most seniors.
- Routine Dental Care: This includes regular cleanings, x-rays, fillings, and dentures.
- Routine Vision Care: Standard eye exams, eyeglasses, and contact lenses are generally not covered.
- Routine Hearing Care: Hearing aids and exams for fitting them are not covered.
- Long-Term Custodial Care: This is the most financially devastating gap for many. Medicare does not pay for non-medical custodial care, such as assistance with daily living activities, in a nursing home or at home.
- International Travel: In most cases, Original Medicare provides no coverage for medical care received outside the U.S.
How to Fill the Gaps in Medicare
For those seeking more comprehensive and predictable coverage, there are two primary options to address the gaps left by Original Medicare. These are Medigap plans and Medicare Advantage plans.
Medigap (Medicare Supplement) Plans
Medigap policies are sold by private insurance companies to help pay for the cost-sharing expenses not covered by Original Medicare. Key features include:
- Standardized Plans: Policies are standardized with lettered plan names (e.g., Plan G, Plan N), with benefits consistent across all insurers.
- Works with Original Medicare: You must remain enrolled in Original Medicare (Parts A and B).
- Covers Cost-Sharing: Medigap plans help cover deductibles, copayments, and coinsurance.
- No Prescriptions: Medigap policies do not include prescription drug coverage; you must enroll in a separate Part D plan.
Medicare Advantage (Part C) Plans
Medicare Advantage plans are an alternative to Original Medicare, offered by private insurance companies approved by Medicare. These plans must cover everything Original Medicare does, but often offer additional benefits. Key features include:
- All-in-One Coverage: Includes Part A, Part B, and often prescription drug coverage (MAPD).
- Extra Benefits: Many plans include routine dental, vision, and hearing coverage, along with wellness programs.
- Network-Based: You may need to use a specific network of doctors and hospitals, unlike Medigap.
- Cost-Sharing: Instead of Medigap, you pay a fixed copayment or coinsurance for services, with an annual maximum out-of-pocket limit.
Comparing Medigap vs. Medicare Advantage
Understanding the differences between these two options is vital for making an informed decision. Here's a quick comparison:
| Feature | Medigap (Supplemental Insurance) | Medicare Advantage (Part C) |
|---|---|---|
| How it Works | Works with Original Medicare to pay cost-sharing (deductibles, coinsurance). | Replaces Original Medicare and provides all-in-one coverage. |
| Prescription Drugs | Requires separate Part D plan. | Often includes Part D coverage (MAPD). |
| Network Restrictions | No network restrictions. See any doctor that accepts Medicare. | Often uses a specific network of doctors (HMO, PPO). |
| Extra Benefits | No coverage for routine dental, vision, or hearing. | Often includes dental, vision, hearing, and wellness benefits. |
| Referrals | No referrals needed to see a specialist. | HMO plans may require referrals. |
| Out-of-Pocket Cap | No annual cap; effectively eliminates most out-of-pocket costs. | Has a fixed annual maximum out-of-pocket limit. |
| Cost Structure | Monthly premium for Medigap plus Part B premium. | Often lower or $0 monthly premium, but with copays/coinsurance. |

Making the Right Choice for Your Health
Deciding how to address Medicare’s coverage gaps depends on your individual health needs, budget, and preference for flexibility. For those who want the freedom to see any doctor who accepts Medicare and can afford the higher premiums, Medigap is often the choice. For those who prefer a single, comprehensive plan that includes extra benefits and caps out-of-pocket spending, a Medicare Advantage plan may be a better fit. Understanding that the most infamous "gap" is gone is the first step; the next is to build a comprehensive plan that secures your financial health for the future.
