Turning 65? Here Are 5 Medicare Mistakes That Could Cost You (and How to Avoid Them)

Turning 65 is a milestone: senior discounts, “golden years” brochures, and the legendary Medicare transition. In a perfect world, Medicare would be as simple as blowing out birthday candles: sign one paper and every doctor’s visit is covered forever.

But we live in the real world, and the American healthcare labyrinth can feel like assembling IKEA furniture without instructions while someone shouts acronyms at you. If the mail and TV commercials have you overwhelmed, take a breath: you aren’t alone, and you don’t have to do this by yourself.

At Allraya, based right here in Missouri, we help our neighbors in West County and across the state sort through their options. So grab a cup of coffee (or tea: we don’t judge) and let’s look at five Medicare mistakes to avoid.

1. MISSING YOUR ENROLLMENT WINDOWS (THE “I’LL DO IT LATER” TRAP)

Enrollment isn’t a Netflix subscription you can start whenever you feel like it. Your Initial Enrollment Period (IEP) is a seven-month window: the three months before the month you turn 65, your birthday month, and the three months after.

Miss your chance to enroll in Part B without qualifying coverage or another enrollment opportunity, and you could face a late-enrollment penalty. In general, that penalty adds 10% to your Part B premium for each full 12-month period you could have had Part B but didn’t. It usually lasts as long as you have Part B.

The Missouri solution: If you’re still working and covered through your or your spouse’s current employer, you may be able to delay Part B, but don’t rely on a “probably.” Employer size and the details of your coverage matter. Ask your benefits administrator whether Medicare or your employer plan pays first, and confirm your enrollment timeline before your IEP ends. You can also talk it through with a Missouri-based Allraya agent.

2. ASSUMING MEDICARE IS TOTALLY FREE

Hate to be the bearer of “not-so-free” news, but there’s a common misconception that healthcare costs drop to zero at 65.

Part A (hospital insurance) is premium-free for most people who have enough work history. Part B (medical insurance) generally has a monthly premium, often deducted from your Social Security benefit. Both can involve deductibles and other costs before or after Medicare pays its share.

And here’s a big one: with Original Medicare, you generally pay 20% of the Medicare-approved amount for many covered Part B services after you meet the deductible. Original Medicare doesn’t have an annual out-of-pocket maximum for Part A and Part B costs. For a $100,000 Medicare-approved service, 20% could mean a very scary $20,000-though the actual amount depends on the service, provider, and any other coverage you have.

How to avoid the shock: Many people look into Medigap plans in Missouri, also called Medicare Supplement Insurance, to help cover certain Original Medicare costs. What a policy pays depends on the plan, so compare the details rather than assuming every policy covers the same expenses. A supplement may help make costs more predictable, but it comes with a monthly premium.

3. IGNORING PRESCRIPTION DRUG COVERAGE (PART D)

“I don’t take any prescriptions, so I don’t need a drug plan” sounds logical. Why pay for something you aren’t using?

But Part D can be a pay-now-or-pay-more-later situation. If you go 63 or more consecutive days after your initial enrollment period without Part D or other creditable prescription drug coverage, you may face a late-enrollment penalty when you sign up later. The penalty is generally based on how long you went without creditable coverage and usually lasts as long as you have Part D.

Since health needs can change in the blink of an eye, having suitable drug coverage can help you avoid a gap if a doctor prescribes something new. Even if you take only a daily vitamin, compare your options and confirm whether any coverage you already have counts as creditable.

Pro tip: Keep any notices about your prescription coverage. If you’re comparing Medicare Part D plans in Missouri, check your medications, pharmacy, plan costs, and coverage rules, not just the monthly premium. Our post on what to check in Medicare Part D can help you get started.

4. CONFUSING MEDICARE ADVANTAGE VS. MEDIGAP

This is the fork in the road where many people get stuck, like choosing between a buffet and an à-la-carte menu.

Medicare Advantage (Part C) plans are offered by private insurers and provide your Part A and Part B benefits through the plan. Many include additional benefits, and some have a $0 plan premium. You generally still pay your Part B premium. Plans often use provider networks, and you may need referrals or prior authorization, depending on the plan.

Medigap (Medicare Supplement Insurance) works alongside Original Medicare. You pay a monthly premium for the policy, and it may help with certain out-of-pocket costs. With Original Medicare, you can generally see any provider nationwide who accepts Medicare. Medigap policies don’t generally include prescription coverage, so you’ll usually need a separate Part D plan if you want drug coverage.

The mistake: Choosing based on a $0 plan premium without checking whether your favorite specialist is in-network, or choosing Medigap without realizing you’ll need to arrange separate Part D coverage.

The fix: Don’t just follow what your neighbor did. Your health needs and budget are unique. Compare your doctors, prescriptions, pharmacies, travel habits, and expected costs against the plans available in your Missouri ZIP code. Our guide to Medicare Advantage and Medigap explains the differences in more detail.

5. THINKING MEDICARE COVERS EVERYTHING

Medicare doesn’t cover everything from a broken toe to a long-term nursing home stay, and assuming it does can lead to big out-of-pocket costs later.

Original Medicare, and most Medigap plans, typically does not cover long-term custodial care, most routine dental care, eye exams for glasses, hearing aids, or cosmetic surgery.

How to handle the gaps: Some Medicare Advantage plans include dental and vision benefits. If you choose Original Medicare with Medigap, you may be able to add a separate dental, vision, or hearing policy. Review what’s covered, what isn’t, and any limits or costs. A little planning now can help prevent choosing between a new pair of glasses and a weekend getaway later.

WHY LOCAL EXPERTISE MATTERS (THE ALLRAYA ADVANTAGE)

You might be thinking, “Can’t I just call the 1-800 number on TV?” You could, but a national call center may not know your favorite doctor is at Mercy Hospital in St. Louis or that you prefer the pharmacy down the street in Manchester.
