What is Medicare Part D?

Medicare Part D is the part of Medicare that helps cover the cost of prescription drugs. It’s optional but highly recommended—especially if you take daily medications or want to avoid future penalties.

Part D plans are offered by private insurance companies approved by Medicare.

Whether you're new to Medicare or just reviewing your options, understanding Part D can save you money and help you make informed choices about your healthcare.

Enrollment periods include initial, annual, and special options.

What Does Medicare Part D Cover?

Part D helps pay for:

Prescription drugs (both generic and brand-name)
Vaccines (including the shingles shot and COVID-19)
Medications that you take at home (not typically covered by Part A or B)

Each plan has a formulary—a list of drugs it covers. These are organized into tiers, which determine your cost.

How Much Does Medicare Part D Cost?

Costs vary by plan and may include:

Monthly premium (national average in 2025 is around $34/month)
Annual deductible (up to $590 in 2025)
Copays or coinsurance based on drug tiers

If you delay enrolling when you’re first eligible, you may face a late enrollment penalty—added to your premium permanently.

Who Needs Medicare Part D?

You should consider enrolling if:

You take any regular medications
You don’t have creditable drug coverage from another source (like employer coverage or VA benefits)
You want future protection even if you don’t currently take prescriptions

When Can You Enroll?

Initial Enrollment Period (IEP) – 3 months before to 3 months after your 65th birthday
Annual Enrollment Period (AEP) – October 15 to December 7 each year
Special Enrollment Periods (SEPs) – If you lose other coverage or move

How to Choose the Right Plan

When comparing plans:

Look at which drugs are covered
Check your pharmacy’s network status
Compare monthly premiums and out-of-pocket costs
Use the Medicare Plan Finder to review options

Final Thoughts: Is Medicare Part D Worth It?

Absolutely—especially if you’re aiming for peace of mind and long-term savings. Prescription drug costs can be unpredictable, and having coverage ensures you're not caught off guard.
