Before You Choose a Plan
Will Your Doctors and Prescriptions Be Covered?
It's the number-one question — and the number-one post-enrollment regret when it's skipped. Before you pick any Medicare plan, it's worth confirming your own doctors are in-network and your medications are on the plan's drug list. Here's how to check, using the official free tools — or let me do it for you at no cost.
Why It Matters
The mistake that follows people for a year
Medicare Advantage plans use provider networks and prescription drug lists (formularies) that change every year. Enroll without checking, and you can discover in January that your longtime doctor is out-of-network or your medication isn't covered — and on most plans you're locked in until the next Annual Enrollment Period. Five minutes of checking prevents a year of surprises.
Step 1
Check whether your doctors are covered
Two things decide this: the type of coverage you choose, and each plan's specific network.
- With Original Medicare + a Medicare Supplement (Medigap), any provider that accepts Medicare — nationwide — is available to you. There's no network to check.
- With a Medicare Advantage plan (HMO or PPO), you're limited to that plan's network, so you must confirm each doctor you want to keep is in it — for the specific plan and year you're considering.
- Networks change yearly. A doctor who was in-network last year may not be next year, so re-check at each Annual Enrollment Period.
How to check yourself
- Make a list of the doctors and hospitals you want to keep.
- Use Medicare's official Care Compare tool to look up providers, or check the specific plan's provider directory.
- Or simplest: call the doctor's office and ask, "Do you accept [exact plan name] for 2026?" — plan names matter, since one carrier offers several.

Step 2
Check whether your prescriptions are covered
Every Part D and Medicare Advantage drug plan has a formulary — the list of drugs it covers, and what tier (cost level) each is on. The same medication can cost very different amounts from one plan to the next.
- List every prescription you take, with the dosage and how often — generics and brand names both matter.
- Note your preferred pharmacy; a plan's cost often depends on using a 'preferred' pharmacy in its network.
- Watch for coverage rules beyond price: prior authorization, step therapy, and quantity limits can affect whether — and how easily — a drug is covered.
How to check yourself
- Go to Medicare's official Plan Finder and create a drug list with your exact medications and dosages.
- Enter your pharmacy, and the tool will estimate your total yearly drug cost under each plan — not just the premium.
- Compare the total (premium + deductible + drug costs), since the cheapest premium is often not the cheapest overall.

Common Questions
Coverage-check questions, answered
Do I need to check networks if I have a Medicare Supplement?
No. With Original Medicare plus a Medicare Supplement (Medigap), you can see any doctor or hospital in the country that accepts Medicare — there's no network. Network checks only matter for Medicare Advantage (HMO/PPO) plans.
How do I find out if my specific doctor is in a plan's network?
Three reliable ways: use Medicare's Care Compare tool, search the plan's own online provider directory, or simply call your doctor's office and ask whether they accept that exact plan for the coming year. Always confirm by the full plan name and year, because one carrier usually offers several different plans.
What is a formulary?
A formulary is the list of prescription drugs a Part D or Medicare Advantage plan covers, organized into tiers that set your cost. Two plans can both 'cover' your drug but place it on different tiers, so your out-of-pocket cost differs. Medicare's Plan Finder shows your estimated yearly drug cost under each plan once you enter your medications.
My drug is 'covered' but expensive. Can a different plan help?
Often, yes. The same medication can sit on a lower tier — or be subject to fewer restrictions — on another plan, which can meaningfully lower your cost. This is exactly the kind of comparison worth doing every year, and it's a big part of what a free plan review checks for you.
What if my doctor leaves the network mid-year?
Networks can change during the year. If your provider leaves, your plan must generally give you notice, and depending on the situation you may have options — continuity-of-care provisions, a Special Enrollment Period, or a switch at the next Annual Enrollment Period. It's worth a quick call to talk through the specifics; that's the kind of thing we help clients handle.
Does it cost anything to have you check for me?
No. Licensed agents are paid by the insurance carriers, not by you, and by law your premium is the same whether you enroll through an agent, directly with the carrier, or on Medicare.gov. The doctor and drug check, the plan comparison, and the yearly review cost you nothing.
How often should I re-check?
Every year during the Annual Enrollment Period (October 15 – December 7). Both networks and formularies change annually, and a plan that fit perfectly this year can shift next year. Re-checking each fall is the single best habit for keeping your costs down.
