Key Takeaways
-
In 2025, your Medicare drug plan might not be accepted at every pharmacy—even if the pharmacy is in your neighborhood.
-
To avoid unexpected costs and access delays, always confirm pharmacy participation with your plan before filling prescriptions.
Pharmacies and Medicare Drug Plans: The Basics You Need to Know
Medicare Part D plans cover prescription drugs, but not all pharmacies accept every plan. In 2025, pharmacy networks remain a critical part of how these plans function. If your pharmacy isn’t part of your drug plan’s network, you might pay full price for your medications—or the pharmacy might not process your plan at all.
While you might assume any large chain or local pharmacy will accept your Medicare drug plan, that isn’t always the case. Plan networks are negotiated and selective. Some pharmacies are considered “preferred,” offering lower copayments. Others may be “standard” or entirely out-of-network.
Understanding this distinction is crucial for avoiding unnecessary costs and ensuring uninterrupted access to your medications.
What Does It Mean for a Pharmacy to Be “In Network”?
Each Medicare Part D plan has a network of participating pharmacies. When a pharmacy is “in-network,” it agrees to accept your plan’s negotiated prices for covered prescriptions. This can include:
-
Preferred pharmacies: Lower copayments and more competitive pricing
-
Standard pharmacies: Higher copayments but still within network
-
Out-of-network pharmacies: Generally not covered unless it’s an emergency or no network pharmacy is available
The key benefit of using a preferred pharmacy is cost savings. For example, your plan may cover a generic drug at $5 at a preferred pharmacy, but the same medication could cost $15 at a standard pharmacy.
2025 Updates: Why It Matters Even More This Year
In 2025, Medicare has introduced a $2,000 annual cap on out-of-pocket drug costs under Part D. This change makes the structure of your pharmacy network even more important:
-
Reaching the cap: You’ll want to be sure all costs count toward the cap, which only happens when prescriptions are filled at in-network pharmacies.
-
New pricing models: Some plans now offer tiered pricing that varies not just by drug tier, but also by pharmacy level (preferred vs. standard).
-
Prescription Payment Plan: You can spread out your drug costs across the year, but only if the pharmacy participates and integrates with your plan’s billing system.
What to Ask Before Choosing or Using a Pharmacy
Before you fill your next prescription, here are important questions you should ask:
1. Is This Pharmacy in My Plan’s Network?
Even if a pharmacy accepts Medicare Part D in general, it doesn’t guarantee your specific plan is included. Contact the pharmacy directly or check your plan’s online directory to confirm.
2. Is This a Preferred or Standard Pharmacy?
Being in-network is good, but being a preferred pharmacy can save you more. You can usually find this designation on your plan’s summary of benefits or through its customer service line.
3. Are All My Medications Available Here?
Some pharmacies don’t stock certain medications or may have limited supply. This could delay your treatment or force you to look elsewhere. Check availability, especially for specialty drugs or injectables.
4. Does This Pharmacy Participate in My Plan’s Payment Program?
With the new Prescription Payment Plan in 2025, ask whether the pharmacy supports spreading payments over 12 months. Not all pharmacies may be integrated with your plan’s billing features.
Using Mail-Order Pharmacies: What You Should Consider
Mail-order pharmacies are often included in your drug plan and can offer savings and convenience. However, before enrolling in mail-order services:
-
Confirm network participation with your plan
-
Ensure timely delivery by checking the typical turnaround time
-
Coordinate refills to avoid running out of medication
-
Watch for local restrictions as some drugs can’t be shipped depending on your state laws
Mail-order can be a good option for maintenance medications, but it may not be ideal for short-term or urgent prescriptions.
Traveling or Relocating? Here’s What Changes
If you’re traveling for an extended time or moving to another state, your pharmacy network access could be affected. Here’s what to do:
-
Check your plan’s national pharmacy network to see if there are partner pharmacies in your new location
-
Call your plan ahead of time to update your location and ask about regional coverage differences
-
Use plan-specific mobile apps to locate the nearest in-network pharmacy
-
Avoid filling prescriptions at out-of-network pharmacies unless it qualifies as an emergency
Some Medicare drug plans operate regionally, and others offer broader access. Either way, it’s your responsibility to verify access.
What Happens If You Fill at an Out-of-Network Pharmacy?
There are consequences to using a pharmacy that isn’t in your plan’s network:
-
You may have to pay full cost of the medication upfront
-
Costs may not count toward your $2,000 annual cap
-
Reimbursement may be denied unless there is a documented emergency or plan-approved exception
-
You may face delays getting the prescription approved or filled again at another pharmacy
Sometimes, you can request an exception or reimbursement from your plan, but these processes can take time and are not guaranteed.
Special Cases: Long-Term Care and Specialty Pharmacies
Medicare drug plans often include specialized pharmacies for:
-
Long-term care facilities
-
Home infusion therapy
-
Specialty drugs that need special handling
These pharmacies may not be local or retail-based but are still part of your plan’s network. Always confirm which services are available and how delivery is managed.
Ask your provider and plan about coordination with these services, especially if you’re receiving treatment for chronic conditions.
How to Check Pharmacy Participation
To verify whether a pharmacy is in-network:
-
Use your plan’s online pharmacy lookup tool
-
Call the pharmacy directly and ask them to check using your plan name and BIN number
-
Contact your plan’s customer service line
-
Review your plan’s Evidence of Coverage (EOC) booklet or Summary of Benefits
Checking once a year isn’t enough. Plan networks can change annually during the Medicare Open Enrollment Period (October 15 to December 7).
Your Role During Medicare Open Enrollment
During Open Enrollment, you can:
-
Switch Part D plans if your pharmacy is no longer covered
-
Compare plans based on pharmacy network and preferred pricing
-
Use Medicare Plan Finder to evaluate options that include your pharmacy
If you don’t review your plan annually, you could unknowingly end up with reduced pharmacy access or higher out-of-pocket costs.
Take Time to Confirm Before You Fill
In 2025, pharmacy access under Medicare Part D depends heavily on network participation. Don’t assume your usual pharmacy will always be covered. Even small changes in your plan’s network or pricing structure can affect what you pay and where you can go.
To make sure you’re covered and paying as little as possible:
-
Confirm pharmacy participation with your plan before every major refill
-
Review your plan’s materials each year
-
Use the Annual Enrollment Period to switch if needed
