Wondering if it’s sensible to enroll in a Medicare prescription drug plan? It may be a good idea if you routinely take pricey prescription drugs. You may also want to get covered if your current prescription drugs are slated to rise in the future and you may not be able to afford the copayments. Here’s what you need to know so you don’t miss out.

Medicare Prescription Drug Plans: An Overview

Worried about prescription drug costs? A Medicare prescription drug plan may offer much-needed relief at an affordable price. But what are Medicare prescription drug plans and how do they work? 

For starters, it’s helpful to know that they comprise 1 of 4 types of plans: 

Medicare prescription drug plans supplement Original Medicare plans because most don’t offer prescription drug coverage. They offer 4 tiers of coverage to make drug costs more affordable:

  • Tier 1: Generic prescription drugs 
  • Tier 2: Preferred, brand-name prescription drugs
  • Tier 3: Non-preferred, brand-name prescription drugs
  • Specialty tier: High-cost prescription drugs

Higher tiers mean you’ll make more expensive copayments. But you may qualify for a lower copayment for medications in a higher tier if you file an exception with your provider. 

Professionally-administered drugs may be covered under Original Medicare or Medicare Part A and B but these plans can help you save even more money on prescriptions. 

Quick note: If you’re currently enrolled in a Medicare Advantage plan that offers prescription drug coverage, the provider will terminate your policy if you join a Part D plan. Most Medicare Advantage policies include coverage for prescription drugs, so it wouldn’t make sense to carry both. 

If you don’t have adequate prescription drug coverage or are paying out of pocket, a Medicare Part D plan is definitely worth considering. Medicare Supplemental Insurance (or Medigap) won’t help offset prescription drug costs — it only works with Part A and Part B plans. 

You can get a quote for coverage right away by entering your age and ZIP code. It only takes a minute of your time, and there’s no obligation to enroll.

Medicare Prescription Drugs Plans Eligibility

To be eligible for a Medicare prescription drug plan, you must meet the following criteria: 

  • 65 years of age or older
  • Have Original Medicare
  • Younger with a qualifying disability 
  • Have end-stage renal disease that mandates dialysis or a kidney transplant

The enrollment windows for Medicare prescription drug plans are as follows: 

  • Initial enrollment period: Spans a total of 7 months (3 months before your 65th birthday, your birthday month and 3 months following your 65th birthday)
  • Annual enrollment period: October 15 to December 7 
  • Special enrollment period: You can enroll at any time for select circumstances.

Medicare Prescription Drug Plans Cost

Drug costs under most Medicare Part D plans are low; the amount you pay will vary by provider. There are 5 types of expenses to know: 

  • Premiums: The amount paid each month to keep your plan active.
  • Annual deductible: The amount you must pay before coverage kicks in. By law, this amount is capped at $435 annually and some plans require no deductible. 
  • Copayments: The set amount you pay each time you fill a prescription.
  • Coinsurance: The percentage of the drug cost you’re responsible for.
  • Coverage gap costs: Applies once your plan covers $4,020 in drugs — it also means you’ll be responsible for higher out-of-pocket costs.

Frequently Asked Questions

Are you wondering what people are asking for about Medicare? See if you have some of the same questions.

1) Q: What are the different parts of Medicare?

1) Q: What are the different parts of Medicare?

Medicare has 4 parts named Parts A, B, C, and D. Part A provides hospitalization coverage while Part B provides outpatient coverage, like doctor visits. Parts A and B make up Medicare’s core coverages. Part C is provides private-market Medicare plans, called Medicare Advantage Plans. Part C coverage often includes additional benefits. Medicare Part D provides coverage for prescription drugs. Get a Medicare Insurance Quote through the top providers here.


2) Q: Is Medicare free?

2) Q: Is Medicare free?

Because there are 4 parts to Medicare, there can be different cost structures. Most people won’t have to pay for Medicare Part A (hospitalization). Eligibility for premium-free Part A is based on your work history during which you paid Medicare taxes. Many people do pay a monthly premium for Medicare Part B, however, which covers outpatient medical services, like doctor visits. Deductibles also apply to services covered under Medicare Parts A and B, so you’ll pay a part of the annual cost.

Medicare Parts C and D are optional coverages and have premium costs of their own. Medicare Part C refers to Medicare Advantage Plans that offer additional coverage in exchange for a monthly premium. Part D, the prescription plan, reduces the cost of medications but also requires a monthly premium. Subsidies may be available for low income households to help reduce overall Medicare costs.


3) Q: Do I need to sign up for Medicare?

3) Q: Do I need to sign up for Medicare?

If you signed up for Social Security before age 65, you were enrolled in Medicare automatically but benefits will begin at age 65. In most cases, there are penalties for not enrolling at age 65, so it pays to sign up on time. Click here to get a medicare quote in minutes from the best providers. 

If you have employer coverage, you may be able to delay Medicare coverage while your work plan is still in force. However, the size of the employer determines whether you’ll pay a penalty for not enrolling at age 65. Employees (and their spouses) of companies that offer group health insurance to 20 or more people are usually exempt from late sign-up penalties if they are covered by the employer’s plan.
