Linda enrolled in a zero-premium Medicare Advantage plan at 65 because the math looked obvious: keep more of her Social Security check, skip the Medigap premium, and use the dental and vision extras. For six years, it worked. Then at 71, she had an ischemic stroke, spent five days inpatient, transferred to a skilled nursing facility for three weeks, and started outpatient physical and speech therapy three times a week. Her plan’s in-network out-of-pocket maximum for 2026 is $9,250, the federal ceiling for Medicare Advantage medical cost-sharing. She hit it by August.

If you are healthy, in your 60s, and reading this because a $0 premium plan looks like found money, the question is what you pay in the year something goes wrong, and whether you can still change your mind after it does.

The mechanic that decides a bad year

Original Medicare plus a Medigap Plan G works as a stop-loss for Medicare-covered medical services. After the $283 Part B deductible in 2026, Plan G generally pays the 20% Part B coinsurance Medicare leaves behind, the $1,736 Part A inpatient deductible, and the $217-per-day skilled nursing coinsurance that begins on day 21. A 71-year-old paying an illustrative $150 monthly Plan G premium spends about $1,800 on the supplement for the year, plus the Part B deductible. Total exposure for covered medical care in a stroke year: about $2,083, not counting Part D drug costs.

Medicare Advantage works differently. The plan premium may be low or zero, but the cost-sharing shows up when care is used: hospital copays, skilled nursing facility copays, specialist copays, outpatient therapy copays, and coinsurance for some Part B drugs. Those costs can add up until the enrollee reaches the plan’s in-network maximum, which can be as high as $9,250 in 2026. In a PPO, out-of-network care can count toward a higher combined limit, capped at $13,900 in 2026; in an HMO, non-emergency out-of-network care may not be covered at all.

The advertised medical maximum also excludes Part D drug spending. New stroke medications, such as anticoagulants, statins, and blood pressure drugs, may bill through the plan’s drug benefit, which has its own cost-sharing rules and a separate 2026 out-of-pocket cap.

The gap, in one table

In a healthy year, the Advantage plan saves about $1,800 compared with the illustrative Plan G premium. In a stroke year where the Advantage enrollee reaches a $9,250 in-network maximum, Plan G saves about $7,167 on covered medical costs. Five healthy years of premium savings can disappear in one bad year, and stroke, cancer, hip fracture, and heart failure do not announce themselves on a schedule.

The switch-back trap

Linda’s instinct after the stroke was to switch to Original Medicare during open enrollment and buy a Medigap policy. She can do the first part. The second part is where most readers get caught.

The federal six-month Medigap open enrollment window runs once, starting the first month a person is 65 or older and enrolled in Part B. After that window closes, insurers in most states can medically underwrite, and a recent stroke can make an application much harder or more expensive. Some states offer broader Medigap protections, including continuous or periodic guaranteed-issue rights, but most do not. The choice Linda made at 65 was closer to permanent than the brochure suggested.

The income side most readers miss

A 2.8% Social Security COLA for 2026 raised the average retired-worker check by roughly $56 a month. The standard Part B premium rose $17.90 to $202.90, taking about one-third of that average increase before the retiree saw a dollar. A large medical bill in that environment can overwhelm the savings from years of paying no Medicare Advantage plan premium.

What to do

• If you are about to turn 65 and considering Medicare Advantage, price Original Medicare plus Plan G or high-deductible Plan G in your ZIP code before you enroll. The six-month Medigap window opens when you are 65 or older and enrolled in Part B, and it does not repeat every year like Medicare open enrollment.

• If you are already on Medicare Advantage and healthy, do not assume fall open enrollment gives you a guaranteed Medigap policy. Check your state’s Medigap rules, ask whether any guaranteed-issue right applies, and get underwritten while you are still healthy if switching back to Original Medicare with a supplement is part of your plan.

• If you stay on Advantage, read the Summary of Benefits for the in-network and combined out-of-pocket maximums, and confirm your hospital, oncologist, and nearest rehab facility are in-network. In a bad year, the cost-sharing, not the premium, drives the bill.

The premium is only the first number

A zero-premium Medicare Advantage plan can be the right choice for some retirees, especially when doctors, hospitals, and prescriptions fit the network and formulary. The risk is mistaking a low premium for a low-cost year. Before enrolling, compare the premium you save with the maximum you could owe when your health changes.
