What You Need to Know Before Choosing Medicare Part D Coverage
Medicare Part D is designed to help you manage prescription drug costs, but if you take expensive medications, you’ll need to be extra careful about choosing the right plan. Not all Medicare Part D plans cover the same drugs or have the same cost-sharing structures, so knowing what to look for can make a big difference in what you pay each year.
Before making any decisions, here are seven essential questions to ask yourself when planning your Part D coverage.
1. Does the Plan Cover All of My Medications?
Every Medicare Part D plan has its own formulary, or list of covered drugs. Just because one plan covers your medication doesn’t mean another will, so it’s crucial to check before enrolling.
-
Look for tier placement: Medications are often placed in different tiers, affecting how much you’ll pay. Generic drugs are typically in lower tiers with lower costs, while specialty drugs are in higher tiers with higher costs.
-
Consider coverage restrictions: Some plans may require prior authorization, step therapy, or quantity limits, which can affect your access to certain drugs.
-
Review the formulary annually: Medicare Part D plans can change their formularies each year, so even if a plan works for you now, you’ll need to confirm coverage again during Open Enrollment (October 15 – December 7).
2. What Will My Out-of-Pocket Costs Be?
Understanding how much you’ll pay out-of-pocket for prescription drugs under Medicare Part D can help you avoid surprises.
-
Annual deductible: Some plans charge a deductible before coverage kicks in. The maximum deductible in 2025 is $590.
-
Copayments and coinsurance: You’ll either pay a flat fee (copayment) or a percentage of the drug’s cost (coinsurance).
-
Annual out-of-pocket maximum: New for 2025, Medicare Part D now has a $2,000 cap on out-of-pocket drug expenses, providing significant relief for those who take high-cost medications.
3. Will My Pharmacy Accept My Plan?
Not all pharmacies accept every Medicare Part D plan, and costs can vary based on whether your pharmacy is in-network or out-of-network.
-
Preferred vs. standard pharmacies: Some plans have preferred pharmacies where you’ll pay lower costs compared to standard pharmacies.
-
Mail-order options: Many plans offer mail-order pharmacies, which can be a cost-effective option for maintenance medications.
-
Retail pharmacy restrictions: If you have a preferred pharmacy, check whether it participates in your chosen plan to avoid unexpected higher costs.
4. How Will the Medicare Part D Phases Affect My Costs?
Medicare Part D coverage is divided into different phases, and understanding these can help you budget effectively.
-
Deductible phase: You pay the full cost of medications until you reach your deductible (if applicable).
-
Initial coverage phase: After meeting the deductible, you’ll pay a copay or coinsurance until your total drug costs reach $5,030 in 2025.
-
Catastrophic coverage phase: Thanks to changes in 2025, once you hit $2,000 in out-of-pocket drug costs, you won’t pay anything for covered medications for the rest of the year.
5. What Happens If My Medication Isn’t Covered?
If your medication isn’t on a plan’s formulary, you have several options to avoid paying full price.
-
Request an exception: If your doctor believes a drug is medically necessary, they can request a formulary exception from the plan.
-
Look for alternative medications: Some plans may cover a similar medication that your doctor can prescribe instead.
-
Appeal a denial: You can appeal a decision if your plan refuses to cover a necessary drug.
6. Can I Change Plans If My Needs Change?
Medicare offers certain periods when you can change your Part D coverage.
-
Annual Open Enrollment (October 15 – December 7): This is the main time to switch plans if your current one no longer meets your needs.
-
Special Enrollment Periods (SEPs): You may qualify for an SEP if you experience a qualifying life event, such as moving to a new service area or losing other drug coverage.
-
Medicare Advantage Open Enrollment (January 1 – March 31): If you have a Medicare Advantage plan with drug coverage, you can switch to another plan or return to Original Medicare with Part D.
7. What Are the Best Ways to Save on My Prescriptions?
Even with Medicare Part D, prescription drugs can be costly. Here are a few ways to reduce your expenses:
-
Use generic or lower-tier medications: Ask your doctor if there’s a lower-cost option available.
-
Compare plans annually: Drug costs can change, so reviewing plans each year can help you find one with lower out-of-pocket expenses.
-
Look into extra assistance programs: Programs like Medicare’s Extra Help can lower prescription drug costs for those who qualify.
-
Utilize manufacturer assistance programs: Some drug manufacturers offer financial assistance to Medicare enrollees.
