Medicare Part D Prescription Plan

Medicare Part D provides a prescription drug benefit that’s separate from traditional Medicare Parts A and B. You can enroll in Part D through standalone prescription drug plans (PDPs) or Medicare Advantage plans that include coverage for prescription drugs.

Medicare Part D provides crucial coverage for medications. It saves Medicare beneficiaries from paying the high drug costs of prescription drugs. If you are facing issues related to Medicare or need help in understanding prescription drug coverage, consider speaking with a healthcare attorney. They can ensure that you are getting the coverage that you are entitled to under the laws of the federal government.

What Is a Medicare Part D Plan?

Medicare Part D fills a gap in traditional Medicare coverage by providing prescription drug benefits. Everyone with Medicare has the option to add this coverage through insurance companies and other private companies approved by Medicare. Part D works together with your other Medicare coverage. If you have Original Medicare (Parts A and B), adding Part D gives you comprehensive coverage. If you choose Medicare Advantage (Part C), most plans already include prescription drug coverage.

Types of Medicare Prescription Drug Plans

There are two basic types of Medicare Part D prescription plans. Let’s take a look at each one to see what they offer:

Prescription Drug Plans (PDPs)

PDPs are stand-alone programs that focus on and cover prescription drugs only, as opposed to other healthcare needs. People who already have Original Medicare (Part A or B) typically choose PDPs.

Advantage Plans with Prescription Coverage (MA-PDs)

MA-PDs are Medicare Advantage Plans that also cover prescription drugs. They come in four types: HMOs, PPOs, PFFS, and Special Needs Plans (which are only for very specific groups of people). These are managed care programs that often require you to use certain doctors and hospitals, but offer lower costs.

The type of plan you choose will be based on the amount of money you can spend and the type of coverage you need. Take the time to do your research and find the best plan for you.

Eligibility for Medicare Part D Prescription Plans

If you’re eligible for Medicare Part A (hospital coverage) or Part B (medical insurance), you are also eligible for Medicare Part D. Part D benefits work together with your other Medicare coverage. If you have Original Medicare (Parts A and B), adding Part D gives you coverage for medications. If you choose Medicare Advantage (Part C), most plans already include prescription drug coverage. Traditional Medicare plans often don’t cover the costs of medications.

General eligibility for Medicare benefits starts when you reach 65 years old. However, you can enroll three months before your 65th birthday. There are also instances where enrollees under 65 years old can qualify for Medicare. You may be eligible for Medicare under age 65 if you have a disability, End Stage Renal Disease (ESRD) or ALS (amyotrophic lateral sclerosis).

In most cases, you can only make changes to your Medicare drug plan during the annual enrollment period (October 15-December 7). Certain qualifying events create special enrollment periods where changes are permitted.

Features of Medicare Part D

Each Part D plan’s formulary (covered prescription drugs) provides a list of medications it covers. The list will tell you the name of the drug it covers and how much your copay is.

If the medication is not on the list, you may be responsible for the costs for that medication. You also have the option to use a drug plan that covers it. Although there are options to apply for an exception to cover the medication you have, it is best that you pick a plan that covers your existing medication.

Changes to Medicare Part D Coverage in 2025

As of January 1, 2025, Medicare Part D coverage underwent significant changes. This change was caused by the Inflation Reduction Act (IRA), a prescription drug law. This law simplified prescription drug coverage and established a $2,000 annual cap on out-of-pocket spending for Medicare-covered medications. According to the HHS,, these benefit changes will reduce annual out-of-pocket medication costs by an average of 30%.

Medicare Part D coverage now consists of a three-phase benefit.

• First is the deductible phase. You pay the full cost of your medications until you hit your plan’s deductible. The amount of the deductible may vary depending on the plan.
• Next is the initial coverage phase. During this stage, you often have to pay a portion of the costs of your medication. The plan covers the rest. This continues until the out-of-pocket costs you spend reach $2,000.
• After you’ve spent $2,000 out-of-pocket costs, you will pay nothing more for covered prescription drugs for the rest of the year.

Knowing your deductibles can help you figure out what you’ll end up paying out of pocket.

Choosing a New Medicare Part D Plan

Picking a plan can seem like a monumental task, but it boils down to some simple questions. Ask yourself the following:

• How much does the plan cost?
• What drugs does the plan cover, including brand name drugs or generic drugs?
• What are your existing health and outpatient medication needs?
• What is your existing insurance coverage?
• Do your have specific hospitals, doctors, or pharmacy networks you wish to use?

People often choose the cheapest Part D plan without checking if it covers the specific medication they take, which could lead to higher costs later. Part D plans have drug lists that you should check before enrollment. Keep in mind that you cannot switch plans during the year. Changes are only permitted during the enrollment period. Medicare can also deny coverage of drugs not included in your plan.

If the drugs you take now are currently covered under your existing plan or you don’t take any prescription drugs, you should still consider a Medicare Part D prescription plan. In many cases, Medicare will let you keep your existing prescription drug plan or offer you alternatives. Deciding to enroll at a later date may get you penalized. It pays to explore your eligibility for Part D even if you’re currently covered or don’t have any need.

Costs of Medicare Part D Prescription Plans

Medicare Part D plan comes with three primary costs:

Monthly Premiums

Most plans charge a monthly premium from the insurance company, and the amount varies depending on the plan.

Yearly Deductibles

You will have to pay for a yearly deductible before your plan coverage covers costs.

Copayments

Each time you fill a prescription, you may have to pay a fixed copayment. Coinsurance medication costs are generally higher. like 25% of the cost of the medication.

You can offset these payments if you qualify for extra help. Visit the Medicare website for additional information.

Getting Medicare Part D Costs Waived

If your income falls below a certain level, you may qualify for Extra Help. Extra Help is a low-income subsidy that assists qualified individuals in paying for their Medicare Part D premiums, deductibles, and coinsurance costs.

You automatically qualify for this assistance program if you:

• Have Medicaid coverage
• Receive assistance from your state in paying your Part B premiums such as Medicare Savings Programs
• You receive Supplemental Security Income (SSI) from Social Security

The federal government reviews the eligibility for Extra Help yearly. To get Extra Help, you must have income and resources below a certain amount. In 2024, the income caps were $22,590 for individuals and $30,660 for married couples.

With Extra Help in 2024, you will pay no greater than $12.15 in 2025 for every medication that your Medicare drug plan covers. Once your total prescription drug costs reach the $2,000 out-of-pocket maximum, you are no longer required to pay for the covered medications. The government also waives the Part D late enrollment penalty if you are receiving Extra Help.

Seek Legal Advice From an Attorney

When choosing Medicare prescription drug coverage, take note of the medications that you take. You should also consider other factors such as your health conditions, medical history, and the medical services you might need from healthcare providers.
