How to Check Your Doctors and Drugs in a Medicare Plan

Why this step matters most

Most Medicare frustration comes from a surprise after enrolling: a specialist who isn’t in network, or a prescription that costs far more than expected. CMS’s own advice for joining a plan is to check that the plan covers your prescriptions and to ask your doctors and pharmacies whether they’re in network. This guide turns that into a checklist.

Step 1: write your list

Kris collects the same list through her Rx drug lookup form, so you can send it once.

• Every doctor you see regularly — primary care and specialists — with their practice name and address.
• Hospitals and health systems you’d want to use. In the Toledo area, network differences between systems can be the deciding factor.
• Every prescription: exact name, strength, dose and how often you fill it. Include inhalers, insulin and injectables.
• Your pharmacy, and whether you use mail order.

Step 2: check doctors and hospitals

If you’re choosing Original Medicare with Medigap, the question is simpler: does the doctor accept Medicare? Kris checks that for you with CMS’s Care Compare data on doctors and hospitals that work with Medicare.

For a Medicare Advantage plan, check the plan’s provider directory, then call the doctor’s office and ask, “Are you in network for this specific plan in 2027?” Offices often take some plans from a company but not others. HMOs generally require network providers except for emergencies, urgent care and out-of-area dialysis, and often need referrals for specialists. PPOs cover out-of-network care at a higher cost.

Step 3: check every prescription

Each plan has its own formulary (drug list) and tiers. Look up each drug and note four things: whether it’s covered, its tier, your copay or coinsurance, and any rules such as prior authorization, step therapy or quantity limits. If a drug isn’t covered or is on a high tier, you or your prescriber can ask the plan for an exception.

Then compare estimated yearly cost — premium plus what you’d pay for your drugs — across plans. CMS suggests adding all the drugs you take regularly when comparing so the estimate is accurate. Remember the yearly cap on covered drug costs: $2,100 in 2026 and $2,400 in 2027.

Step 4: check the pharmacy

Plans have pharmacy networks, and many have “preferred” pharmacies with lower copays. Confirm your pharmacy is in network for the plan you’re considering, and whether mail-order saves money for drugs you take every month.

Step 5: think about travel and the year ahead

If you spend part of the year in another state — many northwest Ohio clients winter in Florida — ask how the plan covers you there. Medicare Advantage networks are local, while Original Medicare is accepted by participating providers nationwide. Plans can also change networks and drug lists, so re-check every fall during Open Enrollment (October 15 – December 7).
