22 Medicare Enrollment Checks Before Next Year's Coverage Starts

The Annual Notice of Change lists next year’s plan terms, but the envelope in your drawer won’t tell you whether a new choice took hold.

Read to the end: #1 is the enrollment-record check that catches an unfinished change, and almost nobody does it.

The envelope arrived while you were sorting mail at the kitchen counter. You set it beside a grocery receipt, then moved both into the drawer. Now another letter has arrived, and the first one is still under the takeout menus.

Putting it away didn’t change your coverage. But assuming next year will work like this year leaves the plan, pharmacy, and drug prices unchecked. Medicare’s fall enrollment period gives you a chance to compare and change plans before the new coverage year starts.

Here are 22 checks to make before that chance closes.

22Pull the plan notice from the drawer

The unopened envelope holds changes your old card won’t show.

Your plan sends an Annual Notice of Change before the next coverage year. It lists changes to costs and coverage. That notice deserves a read even when you like the plan you have.

The letter puts next year’s terms in one place. Leave it unopened, and a changed drug cost or network rule stays hidden until you use your coverage.

This week, find the envelope or request another copy from the plan. Put a mark beside every change that touches a doctor, drug, or bill. “Could you send me another Annual Notice of Change?”

Keep it beside you while you check what the changes mean.

21Circle the dates on your calendar

A good comparison is useless after the enrollment window closes.

Medicare’s fall Open Enrollment runs October 15 through December 7. A plan change made during that window takes effect January 1. Before it opens, you still have time to gather the details that make a comparison worth doing.

Miss December 7, and the usual fall chance to change your Medicare Advantage or Part D plan is gone. Other enrollment opportunities have separate rules, so don’t build this decision around the hope of another window.

This week, circle both dates and set a reminder before the closing day. Choose a second day for checking the result, not just making the choice. “Can we finish this before December 7?”

That calendar entry gives the letters in your drawer a job.

20Identify the coverage you already have

You can’t compare plans until you name your current coverage.

Look at your cards and letters. Original Medicare pairs Part A and Part B; a separate Part D plan covers drugs. A Medicare Advantage plan provides your Part A and Part B benefits through the plan.

Get this wrong, and you risk comparing plans that don’t fit your current setup. A stack of careful price notes won’t help if it answers the wrong question.

This week, write the names and member numbers from your current cards on one sheet. Keep the sheet private, especially if you’re using a shared phone. “Which plan am I enrolled in right now?”

That answer determines which documents to put on the table next.

19Compare next year’s premium and deductible

Older woman comparing two plan documents at her kitchen table.

The price you know today is this year’s price.

Find next year’s premium and deductible in the plan’s Annual Notice of Change or Evidence of Coverage. The premium is the amount you pay to keep the plan. A deductible is what you pay toward covered care or drugs before certain plan payments begin.

A lower premium doesn’t settle the comparison if the deductible or visit costs change. Look at the services and prescriptions you actually use, rather than a sample person in a sales brochure.

This week, put this year’s figures beside next year’s on paper. If a figure is hard to find, call the plan and ask where it appears in next year’s documents. “What will my premium and deductible be in January?”

A monthly figure still leaves the question of what a visit costs.

18Find the copay for your regular visits

Older woman writing visit costs in a notebook at her desk.

Your usual appointment deserves its own line in the budget.

A plan’s Evidence of Coverage lists what you pay for covered services. Look up primary care and specialist visits separately. If you see a physical therapist or another provider regularly, check that service too.

A familiar premium won’t protect you from a changed charge at each appointment. Put repeat visits on paper; they’re easier to overlook than a single large bill.

This week, list the visits you expect to repeat next year. Beside each, write the plan’s stated copay or coinsurance. “Where is the cost for my specialist visit in next year’s coverage document?”

Then check whether the person you see is still in reach.

17Call the doctor’s billing office directly

Older woman calling a doctor’s office from her living room.

An old appointment card proves nothing about next year.

Provider directories change, and a doctor’s office knows which plan contracts it expects to use. For Medicare Advantage, check the exact plan name, not just the insurance company. One insurer sells different plans with different networks.

A familiar doctor outside your plan’s network creates a different bill or a search for a new doctor. For Original Medicare, ask whether the practice still accepts Medicare and whether your doctor is taking patients under it.

This week, call the office that handles billing. Read the plan’s full name from your card, then ask about the coming year. “Will my doctor take this exact plan next year, and at which office?”

Once the office answers, check the places where that doctor sends you.

16Check the hospital your doctor uses

Older woman checking a hospital address on her phone at home.

Your doctor and hospital need separate checks.

An in-network doctor does not establish that every hospital is in your Medicare Advantage plan’s network. Look up the hospital in the plan’s directory. Then call the plan to confirm the exact facility and next year’s network.

If the hospital is outside the network, your doctor’s answer won’t settle the hospital bill. Write down the address, since hospitals in the same system are separate facilities.

This week, find the hospital’s full name and address before you call. Keep the plan’s answer with your notes, not in another stack of mail. “Is this hospital in this plan’s network for next year?”

After that call, turn to the prescriptions waiting in the same drawer.

15Match every prescription to the drug list

One missing drug can change the whole comparison.

A Part D plan or Medicare Advantage drug plan keeps a formulary, its list of covered drugs. Check each medicine by exact name, strength, and form. A tablet and an injection are not interchangeable entries just because their names look alike.

Also check the plan’s drug tier and any stated restrictions. The price you see for one tier tells you little about a medicine placed on another. Don’t stop after finding the first drug on your list.

This week, copy your prescription labels onto one page. Use Medicare Plan Compare to check plans, then confirm unclear entries with the plan. “Is this exact strength covered next year, and what tier is it on?”

The drug list is only part of what happens at the counter.

14Check the rules beside each drug

Older woman marking a drug list with a pen at her table.

A covered prescription can still face an extra step.

Look for prior authorization, step therapy, and quantity limits beside each drug on the plan’s formulary. Prior authorization means the plan requires approval before covering the drug. A quantity limit caps the amount covered within a stated period.

Finding a medicine on the list is not the same as filling it without delay. A restriction gives your prescriber a task to handle before the pharmacy can process that fill under the plan’s rules.

This week, mark every restriction beside a medicine you take now. Call the plan if its wording leaves you unsure what your prescriber needs to submit. “What must happen before the plan covers this prescription?”

Next, check whether the pharmacy you use gives you the price you expect.

13Enter your actual pharmacy in Plan Compare

Older woman entering pharmacy details on her laptop in her kitchen.

The closest counter isn’t always the cheapest one.

Drug plans set prices using their pharmacy arrangements. Medicare Plan Compare lets you enter your prescriptions and pharmacies to estimate what you’ll pay under the plans you’re comparing. Use the location where you actually fill prescriptions, including mail order if that is your routine.

The estimate deserves a second look when your pharmacy changes ownership, location, or plan status. A plan that looks affordable with one pharmacy deserves another comparison with the one near your house.

This week, run the same drug list with your usual pharmacy and another convenient choice. Save or write down the results so you don’t have to recreate them later. “Is my pharmacy preferred for this plan next year?”

A good drug price does not answer who pays the rest of your medical bills.

12Read your Medigap renewal notice

Older woman reading a policy renewal notice at her desk.

Your supplement needs a separate look before you switch.

Medigap works with Original Medicare; it does not pay Medicare Advantage costs. Find your policy’s renewal premium separately from any Part D notice. Then consider what leaving it would mean if you wanted Medigap again.

Federal rules protect the right to buy Medigap in specific situations, but don’t assume you’ll have that right after leaving a policy. State rules differ. Review Medicare’s Medigap information and ask your state insurance department about your situation before canceling coverage.

This week, find the policy name and call the insurer for its renewal premium. Before dropping it, ask your state insurance department: “Would I have a right to buy a Medigap policy later if I switch now?”

Before changing that arrangement, look at what a different plan promises in extras.

11Price the extras you actually use

A long benefits list is not a bill paid.

Medicare Advantage plans advertise benefits beyond Original Medicare, such as dental or vision coverage. Read each benefit’s limits in the Evidence of Coverage. Check the provider rules and your share of the cost before treating the benefit as a reason to stay.

For example, a dental benefit has little value to you if your dentist doesn’t participate or the work you need falls outside the plan’s terms. Compare the benefit with what you paid out of pocket this year, not with the size of the brochure headline.

This week, choose the two extras you used or expect to use. Find their next-year terms and call the plan about the service you need. “What would this dental visit cost me under next year’s benefit?”

Those extras sit beside another number with a different job.

10Locate the out-of-pocket maximum

Older woman writing a plan limit on paper at her table.

A low copay says little about a bad health year.

Medicare Advantage plans have an annual limit on what you pay for covered Part A and Part B services. Find the next-year limit in the plan’s materials. It is separate from premiums and drug costs.

Original Medicare has no annual out-of-pocket maximum for Part A and Part B services. That difference belongs on your comparison sheet, especially if you’re weighing a change from one coverage setup to another.

This week, write the plan’s next-year limit beside its premium. “What spending counts toward this limit?”

Then check the bill that arrives even when no plan sends one.

9Look for the Part B premium deduction

Older woman comparing a benefit notice with a bank statement at home.

A plan premium is not your whole Medicare bill.

Most people pay a Part B premium, including people in Medicare Advantage. If you receive Social Security benefits, the premium is commonly deducted from that payment. Check your benefit notice or Medicare bill to see how you pay it.

Higher-income beneficiaries face an income-related monthly adjustment amount, called IRMAA, for Part B and Part D. Social Security sends the determination notice. If a life-changing event reduced your income, Form SSA-44 is the form to review.

This week, find your latest Social Security or Medicare payment notice. Compare what it shows with your plan’s separate premium. “Am I paying this Part B amount through my Social Security payment?”

Before you set that figure aside, check whether you qualify for help with costs.

8Check Extra Help without guessing your eligibility

Older woman reviewing an application on her laptop at her kitchen table.

Drug costs deserve a separate help check.

Medicare’s Extra Help program helps eligible people pay Part D costs. Income and resource rules apply, and the figures change. Don’t rule yourself out using a number you heard years ago.

An old income figure from a drawer is no substitute for the current rules. If you skip the application based on that figure, you won’t learn whether help applies to your drug costs.

This week, use Medicare’s Extra Help page or contact Social Security about an application. Have your income and resource information ready before you start. “Where do I apply for Extra Help with my drug plan?”

There is another cost program to check with your state.

7Ask your state about Medicare Savings Programs

Older woman calling a state agency with papers spread across her desk.

A federal card does not show every source of help.

Medicare Savings Programs are run through states and help eligible people with Medicare costs. The program you qualify for depends on its rules and your finances. The state Medicaid agency handles the application, not your drug plan’s sales desk.

Medicare has a Medicare Savings Programs page that explains the program types. State rules and current limits matter, so use the state agency’s figures rather than an old handout from the drawer.

This week, find your state Medicaid agency through that Medicare page and ask how to apply. Write down the documents it requests before sending anything. “Which Medicare Savings Program application should I complete?”

Once you know what help is available, inspect any plan pitch that arrives.

6Read the sender on agent mailers

Older woman sorting insurance mail on a hallway console.

A familiar logo is not your current plan.

Marketing mail can resemble an official notice. CMS sets rules for Medicare plan marketing, but a sales letter is still a sales letter. Look for the sender before treating it as a change to your coverage.

Acting on a mailer as if it were your plan’s notice risks a switch based on a pitch rather than your doctors, drugs, and costs. Keep it separate from the envelope you pulled out of the drawer.

This week, sort mail from Medicare, your current plan, and other senders. Call the number on your existing plan card to verify a claim about your coverage. “Did your plan send this letter to me?”

A persuasive letter still cannot tell you whether your prescriptions fit.

5Use one complete list for plan comparisons

Older woman arranging prescription bottles beside her laptop.

Half a drug list gives you half an answer.

Medicare Plan Compare uses the prescriptions and pharmacies you enter to estimate plan costs. If you leave off a regular medicine, the comparison does not account for it. Keep the same list while comparing each plan, so the results rest on the same information.

Include dosage, how often you fill it, and your chosen pharmacies. For medical coverage, keep a separate list of your doctors, hospitals, and regular services. This is the paperwork the drawer was waiting for.

This week, gather the bottles, your current cards, and next year’s notices in one place. Enter the full drug list before sorting plans by estimated cost. “Can you check the results against every medicine on this page?”

When a screen result conflicts with a letter, you need a person who can help sort it out.

4Call your State Health Insurance Assistance Program

Older woman speaking with a counselor across a library table.

You don’t have to compare plans with a salesperson.

The State Health Insurance Assistance Program provides free Medicare counseling. A SHIP counselor can help you work through plan choices and explain the documents in front of you. SHIP is separate from an insurance agent selling a plan.

A missed detail on your drug list or a question about switching coverage is worth raising before you enroll. Bring the paperwork rather than trying to describe it from memory over the phone.

This week, use SHIP’s site to find your local program. Bring your notices, drug list, and written questions to the conversation. “Can we compare these plans using my prescriptions and doctors?”

Then put the choice itself through one final test.

3Read the plan name before submitting

Older woman reading a plan selection on her phone at home.

One similar name can put the wrong plan on your screen.

An insurer sells plans with different networks, drug lists, and costs. Compare the complete plan name and identifying details in your chosen plan’s listing with your notes. Check again before you submit an enrollment request.

A choice built around your doctor or a costly prescription depends on the exact plan. Similar names don’t promise the same network or drug list.

This week, set your written choice beside the final enrollment screen. Read the plan name, coverage type, and start date aloud before clicking. “Is this the exact plan we compared?”

The screen that follows matters as much as the choice you made.

2Save the confirmation from your enrollment

Older woman saving an enrollment confirmation on her phone at her desk.

A closed browser tab is a poor receipt.

After an online enrollment request, keep the confirmation number or save the confirmation page. For a phone enrollment, ask the representative how you will receive confirmation. Record the date, the plan name, and the number you called.

A confirmation shows what you submitted, but it is not proof that the change took hold. Without it, a later call starts with your memory instead of the details of your request.

This week, put the confirmation beside the Annual Notice of Change instead of back in the drawer. Take a screenshot if you used your phone. “What confirmation number should I keep for this enrollment request?”

Now check the record that tells you whether your choice took hold.

1Verify your enrollment in your Medicare account

Older woman checking her Medicare account on a laptop at her kitchen table.

Submitting a choice does not finish your check.

After you submit a plan change, confirm that the plan on your Medicare record matches the one you chose. Sign in through Medicare.gov to review your coverage information. If you cannot sign in, call 1-800-MEDICARE and ask what plan is shown for the new coverage year.

Have your confirmation number and chosen plan name ready. If the record does not match, say so while you have the representative on the line. Ask what steps you need to take and note the call’s date and reference number.

This week, set a calendar reminder to check your record after you submit any change. Keep that reminder even if a welcome packet arrives first. “I enrolled in this plan; can you confirm what Medicare shows for my January coverage?”

That last check is the one to keep outside the drawer.

The bottom line

These 22 checks have one thread: this year’s card cannot confirm next year’s costs, terms, or plan choice.

The best-prepared version of you has opened the notice and compared her real doctors and drugs. She has kept the confirmation number handy for the record check still to come.

Which of these has already happened in your family?

Bonus: The enrollment-record check that catches an unfinished change

  1. Keep the confirmation number and full plan name from your enrollment request.
  2. Sign in at Medicare.gov and check the plan shown for the new coverage year.
  3. If the record differs, call 1-800-MEDICARE. Say: “I submitted a change, but my record shows something else.”
  4. Write down the representative’s instructions, the call date, and any reference number.
