Prescription Drug Coverage — Part D
Medicare Part D Prescription Drug Plans
Call for a Free ConsultationWhat Is Medicare Part D?
Medicare Part D is the prescription drug benefit under Medicare. It is offered through private insurance companies approved by Medicare and helps cover the cost of both brand-name and generic prescription medications.
Part D coverage is available as a standalone Prescription Drug Plan (PDP) that works alongside Original Medicare or a Medicare Supplement plan. It is also often bundled into Medicare Advantage plans (MA-PD), which combine hospital, medical, and drug coverage into one plan.
Each Part D plan has its own formulary — a list of covered drugs — organized into tiers that determine your cost-sharing. Plans also vary by monthly premium, deductible, and the pharmacies in their network. Comparing plans carefully each year can make a significant difference in what you pay at the pharmacy.
How Part D Coverage Works
Formulary Tiers
Part D plans organize covered drugs into tiers — typically from generic drugs at the lowest cost-sharing to specialty drugs at the highest. Your out-of-pocket cost depends on which tier your medication falls into.
Monthly Premiums
Each plan charges a monthly premium that varies by plan and carrier. Some plans may have low or $0 premiums, though premiums, deductibles, and cost-sharing are subject to change annually.
Annual Deductible
Many Part D plans include an annual deductible — the amount you pay out of pocket before the plan begins sharing costs. Some plans waive the deductible for lower-tier drugs.
Pharmacy Networks
Part D plans contract with specific pharmacy networks. Using a preferred in-network pharmacy typically results in lower cost-sharing than using an out-of-network pharmacy.
Catastrophic Coverage
Once your out-of-pocket drug costs reach a certain threshold in a calendar year, you enter catastrophic coverage and pay a reduced amount for covered drugs for the remainder of the year.
Extra Help (Low Income Subsidy)
If you have limited income and resources, you may qualify for Extra Help — a federal program that reduces Part D premiums, deductibles, and copayments. I can help you determine if you qualify.
Why Comparing Plans Each Year Matters
Part D plan formularies, premiums, and cost-sharing can change every year. A plan that covered your medications at a low cost this year may place them on a higher tier — or remove them from the formulary entirely — next year.
During the Annual Enrollment Period (October 15 – December 7), you have the opportunity to review your current plan and switch to a different Part D plan if a better option is available. I can run a side-by-side comparison of plans in your area based on your specific medications.

When Can You Enroll?
Initial Enrollment Period
The 7-month window around your 65th birthday when you first become eligible for Medicare. Enrolling in Part D during this window helps you avoid a potential late enrollment penalty.
Annual Enrollment Period (AEP)
October 15 through December 7 each year. You can join, switch, or drop a Part D plan. New coverage begins January 1 of the following year.
Late Enrollment Penalty
If you go without creditable prescription drug coverage for 63 or more consecutive days after your Initial Enrollment Period ends, you may owe a late enrollment penalty added to your monthly premium for as long as you have Part D coverage.
Special Enrollment Periods
Certain qualifying events — such as losing other creditable drug coverage or moving out of your plan's service area — may allow you to enroll or switch plans outside of the standard enrollment windows.
