Medicare facts vs. myths, the eight most common misconceptions

7 min read

Medicare is a federal program that's almost sixty years old, and like any large institution, it's collected its share of misconceptions. Some of these have been circulating in Polish-American families for years, repeated over coffee after church, in the hair salon, sometimes in Polish-language media. Most sound reasonable, but they cost real money when someone leans on them. Eight myths we hear most often, and what the program really says.

Myth 1: "Medicare covers everything"

Myth

"I have Medicare, so the doctor, the hospital, and the medications are paid for. I don't owe anything else."

Fact

Original Medicare (Part A and B) covers most hospital and outpatient care, but it leaves gaps. There's no annual cap on out-of-pocket costs, no coverage for most prescription drugs, and nothing for dental, vision, or hearing aids. Part B typically pays 80% of the approved amount. The other 20% falls on the patient. That's why most beneficiaries add a supplemental plan (Medigap, Part D) or pick Medicare Advantage (Part C). More in our parts of Medicare guide.

Myth 2: "You have to sign up right at 65"

Myth

"As soon as I turn 65, I have to enroll in Medicare or I'll be penalized."

Fact

It depends on the situation. If your parent is still working and has employer coverage (from a company with at least 20 employees) or coverage through a spouse, they can delay Part B and Part D without penalty, as long as that coverage qualifies as creditable coverage. After retirement, a Special Enrollment Period opens up. People without that kind of coverage should enroll in the seven-month window around their 65th birthday (the Initial Enrollment Period), because each month of late Part B enrollment is a lifetime 10% penalty.

Myth 3: "Medicare Advantage is the same as Original Medicare"

Myth

"It doesn't matter whether I have Advantage or regular Medicare. It's the same program, just a different card."

Fact

The structure is completely different. Original Medicare is the government program. Your parent can go to any doctor that accepts Medicare anywhere in the country, but 20% of costs fall on the patient and there's no annual out-of-pocket cap. Medicare Advantage is a private CMS-approved plan that replaces how benefits are delivered. It works on a doctor network, has its own copays, but caps annual out-of-pocket costs and often bundles Part D plus extra benefits. Both are legitimate and both make sense for different people, but they're two different paths, not the same plan in a different package. We compare them in our Advantage guide.

Myth 4: "You can change plans whenever you want"

Myth

"If I don't like the plan in March, I'll just call and switch."

Fact

Medicare has tightly defined enrollment windows. AEP (October 15 to December 7) is the annual window when anyone can change plans. MA-OEP (January 1 to March 31) lets people already enrolled in Medicare Advantage make one change. Outside these windows, a change requires a specific reason, a move, loss of employer coverage, getting Medicaid, which opens a Special Enrollment Period (SEP). Without one of those reasons, your parent has to wait until October. More in our enrollment guide.

Myth 5: "Medicare covers care in Poland"

Myth

"I'll go to Poland for surgery because it's cheaper, then file with Medicare."

Fact

Original Medicare, as a rule, doesn't cover care outside the United States. There are narrow exceptions (for example, an emergency near the Canadian border while traveling to Alaska), but routine care in Poland (visits, tests, surgeries, medications) is out of pocket. Some Medicare Advantage plans offer limited foreign emergency coverage. It varies plan to plan and doesn't replace regular care. For people who spend part of the year in Poland, a separate travel insurance policy is worth considering.

Myth 6: "Every doctor takes every Medicare, nothing to check"

Myth

"I have a Medicare card, so every office has to take me."

Fact

It depends what kind of Medicare your parent has. With Original Medicare, most doctors in the U.S. accept the program, but some (especially specialists in certain cities) don't take new Medicare patients or require extra fees. With Medicare Advantage, each plan has its own network. A doctor in one plan's network may be out of another's, which means higher costs or no coverage. Before enrolling in an Advantage plan, always check your parent's doctors against that specific plan's network.

Myth 7: "The Medicare card and the Advantage plan card are the same"

Myth

"I have one Medicare card, so I don't need to show anything else at the doctor's office."

Fact

There are two separate cards. The Medicare card is red, white, and blue, issued by federal CMS, with an 11-character number (MBI), confirming enrollment in the program. The Medicare Advantage plan card (or Part D, or Medigap card) is issued by a private insurance company, Aetna, Humana, UnitedHealthcare, BCBS, with its own ID number. Once your parent enrolls in Advantage, the plan card becomes the main one at the doctor's office, and they leave the federal card at home. With a Medigap plan, they show both. Sounds basic, but a lot of clients come in confused after the first visit.

Myth 8: "Medicare is free health insurance for every senior"

Myth

"I worked 40 years, so Medicare is free for me."

Fact

Part A (hospital) is free for most people who worked at least 10 years (40 quarters) paying Medicare taxes. But Part B has a standard monthly premium that rises year over year and is deducted from Social Security. Higher earners pay an IRMAA surcharge on top. Part D has its own monthly premiums depending on the plan. Many Medicare Advantage plans have a $0 premium, but that doesn't mean "free." It means the plan doesn't add a premium beyond standard Part B. All copays, deductibles, and drug costs still apply.

What's worth taking away from these eight myths

All these misconceptions share one thing. They sound reasonable until someone asks for the details. "Medicare covers everything" sounds comforting until a physical-therapy bill arrives. "I can change my plan whenever I want" sounds practical until March comes and it turns out the next chance is October. The best defense is asking concrete questions of your own agent: is my parent's doctor in network, is their drug on the list, when can they change plans, what will they actually pay for a specialist visit. A good agent answers all of these in writing.
