6 Things About Medicare Pricing That Catch Retirees Off Guard

By Erica Coleman · August 12, 2026

You worked 40 years and paid into Medicare every paycheck. You assumed it would be free when you retired. It isn’t — and the costs most people don’t plan for add up to thousands a year.

Medicare is not free health insurance. It’s subsidized health insurance with premiums, deductibles, coinsurance, and coverage gaps that most people don’t fully understand until they’re enrolled and the bills start arriving. Here’s what catches most retirees off guard.

Part B has a monthly premium — and it goes up based on your income. The standard Medicare Part B premium is $185 per month in 2026. But if your modified adjusted gross income exceeds $106,000 for an individual or $212,000 for a couple, you pay more — significantly more. The Income-Related Monthly Adjustment Amount can push Part B premiums above $500 per month per person. A Roth conversion, a one-time capital gain, or selling a rental property in the wrong year can trigger the surcharge.

Part A isn’t free for everyone. Most people qualify for premium-free Part A because they or a spouse paid Medicare taxes for at least 40 quarters. If you didn’t — which includes some people who worked in government, emigrated later in life, or had gaps in employment — the Part A premium can be up to $505 per month in 2026. It’s rare, but when it hits, it’s devastating to a retirement budget that assumed zero premium.

The Part B deductible and coinsurance add up fast. After the $257 annual Part B deductible, Medicare covers 80% of approved services. You pay the remaining 20% — with no annual cap. A $50,000 surgery means $10,000 out of your pocket. A $200,000 cancer treatment means $40,000. Without supplemental insurance (Medigap) or a Medicare Advantage plan, that 20% coinsurance is unlimited.

Part D premiums were kept artificially low — and that subsidy just ended. The Biden-era Medicare Part D Premium Stabilization Demonstration kept monthly drug plan premiums around $36 by paying insurers roughly $16 per enrollee per month. That program ended in 2026. For 2027, Part D premiums are projected to rise for roughly 75% of enrollees, with nearly half seeing increases of $11 to $20 per month.

Medigap premiums increase with age — and some plans use attained-age pricing. A Medigap plan that costs $150 per month at age 65 can cost $400 per month by age 80 under attained-age pricing. Not all states and not all plans use this model, but many do. The premium you’re quoted at enrollment is not the premium you’ll pay for the rest of your life.

Dental, vision, and hearing are largely not covered. Original Medicare does not cover routine dental care, eye exams for glasses, or hearing aids. These are among the most common health expenses for people over 65, and they can cost thousands annually. Some Medicare Advantage plans include limited dental and vision benefits, but the coverage is often capped at $1,000 to $2,000 per year — which barely covers a single crown or pair of hearing aids.

The total out-of-pocket cost of Medicare in retirement — premiums, deductibles, coinsurance, uncovered services, and supplemental insurance — averages roughly $6,000 to $12,000 per person per year depending on health status and plan choices. Budgeting for Medicare as “free” is one of the most common and most expensive retirement planning mistakes.
