What Is Medicare Part D?

Medicare Part D is a prescription drug program run by private insurance companies. You can get coverage by enrolling in a standalone Part D plan or choosing a Medicare Advantage plan that includes drug coverage.

Original Medicare (Parts A & B) does not cover most prescriptions, so a Part D plan helps pay for medications from your local pharmacy. These plans have a monthly premium, deductible, and copays.


When you enroll, you'll get a Part D insurance card to use when filling prescriptions.

How Does Medicare Part D Work?

Medicare Part D consists of several phases, each with different costs for your prescriptions. Whether you have a standalone Part D plan or a Medicare Advantage plan with drug coverage, these rules apply.

Phase 1: The Deductible Phase

At the start of the year, you pay out-of-pocket for your prescriptions until you reach your plan’s deductible.

● Maximum Deductible: In 2026, no Medicare drug plan can have a deductible higher than $615.

● Some plans may waive the deductible for lower-tier, generic drugs.

Phase 2: Initial Coverage

After meeting your deductible, your Part D plan helps pay for your prescriptions. You’ll pay a copay or coinsurance, while the plan covers the rest, until your total out-of-pocket spending reaches $2,100.

Typical Drug Tiers:

Tier 1: Preferred generic drugs (least expensive)

Tier 2: Generic drugs

Tier 3: Preferred name-brand drugs

Tier 4: Non-preferred drugs

Tier 5: Specialty drugs (most expensive)

Phase 3: Catastrophic Coverage Eliminated

In 2026, once you spend $2,100 out of pocket on prescription drugs, you enter the catastrophic coverage phase and won’t have to pay anything more for the rest of the year. This structure makes costs more predictable and helps those with high drug expenses. However, some plans may adjust premiums or structures, so it’s important to review your coverage during open enrollment.

How to Enroll in Medicare Part D

Enrolling in Medicare Part D is simple, but you need to do it at the right time to avoid penalties.

1. Check Your Eligibility – You must have Medicare Part A and/or Part B to enroll in a Part D plan.
2. Choose a Plan – Compare plans based on your medication needs, premiums, deductibles, and pharmacy network.

3. Enroll During the Right Period:

● Initial Enrollment Period (IEP): When you first become eligible for Medicare (3 months before to 3 months after your 65th birthday).

● Annual Enrollment Period (AEP): October 15 – December 7 each year, to switch or join a plan.

● Special Enrollment Period (SEP): If you qualify due to certain life events (e.g., losing employer coverage).

Tip: Even if you don’t take many medications now, enrolling on time helps you avoid late penalties!

Don’t Ignore Medicare’s Annual Election Period

Medicare’s Annual Election Period (AEP) runs from October 15 to December 7 each year and is your chance to review and change your Medicare coverage. During this time, you can switch Medicare Part D plans, change Medicare Advantage plans, or return to Original Medicare. Ignoring this period could mean missing out on better coverage or lower costs.

Assistance with

COVERAGE GAP

In 2026, Medicare Part D will cap out-of-pocket drug costs at $2,100. You’ll generally pay 25% for covered drugs until you reach that limit, after which your medications are fully covered at $0.

Since plans change each year, MAC Insurance can help ensure you have the best coverage and avoid potential gaps.

ADDITIONAL QUESTIONS TO BE ADVISED ON:

How does the new $2,100 out-of-pocket cap affect me?

In 2026, Medicare Part D will limit your yearly drug costs to $2,100. After reaching this amount, your medications are free for the rest of the year.

What happens if I don’t enroll in Part D when I’m first eligible?

If you don’t enroll when first eligible and don’t have other drug coverage, you’ll have to pay a late fee added to your monthly premium forever. The longer you wait, the higher the fee.

Are there programs to help with Medicare Part D costs?

Yes! Programs like Extra Help can lower your drug costs if you qualify. Some states and drug companies also offer discounts.
