The Plan Nobody Shows YouWhat Is the "Cadillac Plan"? The Unlimited-Copay PPO Nobody Shows You
By Dick Tracy · Published August 18, 2026
The unlimited-copay PPO, the plan I call the Cadillac, is a private, medically underwritten health plan where in-network care runs on copays, not coinsurance. You pay a set dollar amount for the visit, the lab, the surgery, even the hospital stay, and the plan pays the rest. Hospitalized for a month? Still the copay. Unlimited doctor days, unlimited hospital days, unlimited cancer treatment, on a nationwide PPO network. It is sold outside the marketplace, so there is no income test, but you do have to qualify medically. That is the trade. Here is how it works, who it fits, and who should skip it.
I'm Dick Tracy, an independent health insurance broker in Western New York, licensed in 25 states with 80+ carriers behind me. I came out of the healthcare side of this business, so there is no gag clause on me. I will give you the tips, the tricks, and the traps. And the biggest trick in my bag is a plan most people have never heard of, because nobody was ever paid to explain it to them. Let me fix that.
What the Cadillac plan actually is
Picture your current plan's summary of benefits. Now cross out every place it says "coinsurance" for in-network care and write in a copay. That is the design. Doctor visits, specialists, labs, X-rays, surgeries, hospital admissions: each one has a set dollar price, and copays for things like labs and imaging bypass the deductible entirely. Free preventive care. Free generic medications, with chronic refills mailed to your door. And one deductible whether you are in or out of network, where a lot of plans quietly double it the moment you cross the network line. Even out of network, you are looking at a copay plus only 10% coinsurance, not the usual painful split.
The "unlimited" part is not marketing. Unlimited doctor days. Unlimited hospital days. Unlimited cancer treatment. The limits that do exist sit on the small stuff, things like chiropractic capped at 12 visits a year and therapy or physical therapy at 16. And it rides on a nationwide PPO network, so the coverage travels with you instead of stopping at the county line.
Coinsurance is the trap. Copays are the fix.
Here is why this design matters. A copay is a known number. Coinsurance is a percentage of a bill you have not seen yet. On a checkup, that difference is trivia. On a hospital stay, it is the whole ballgame. Run 20% coinsurance against a $50,000 hospital bill and you are staring at $10,000, and you keep paying until you hit your out-of-pocket maximum. The math doesn't math, and you find that out at the worst possible moment. On the unlimited-copay design, that same admission is capped at a set copay whether you are there two days or thirty. The worst day of your year stays a known number.
Who qualifies (and who honestly should not apply)
Now the trade. This plan is medically underwritten, meaning the carrier prices it on you, and it comes with a multi-year health look-back. Reasonably healthy people and families sail through. A recent serious diagnosis usually means a decline, and if that is you, I will tell you straight: the guaranteed-issue marketplace is your friend for now, and we can revisit the private market down the road. These plans also will not cover certain medication categories, ADHD stimulants and sleep medications among them, so if you depend on one of those, we price it cash-pay first and see if the total still wins. Anyone who tells you one plan fits everybody is selling, not educating. This plan is spectacular for the people it fits and simply unavailable to the people it does not.
Why no broker ever showed you this
Three reasons, none of them a conspiracy. First, captive agents can only sell what their one company carries, and most companies do not carry this. Second, the marketplace is the path of least resistance: an enrollment takes minutes, while an underwritten plan means checking your doctors, your medications, and your health history person by person. I happen to think that work is the job, but I am in the minority. Third, in community-rated states like New York, getting access to underwritten coverage takes an extra step through group rules, the same route I walk through on my ERISA cheat-code page, and most agents never learned it.
One honest caveat: if you qualify for a large marketplace subsidy, the marketplace may genuinely be your best deal, and I will say so. But with the 2026 subsidy cliff, a lot of people just became full-price customers overnight, and full-price marketplace versus the Cadillac is not a close race for healthy applicants.

You own it, and that matters more than people think
A group plan at work belongs to your employer. Leave the job, or watch the company switch carriers, and your coverage changes with it. This plan belongs to you. It is guaranteed renewable: you answer the health questions once, and you can keep it all the way to Medicare, through job changes, moves, and whatever your health does after the ink dries. That last part is the piece people undervalue. You buy this plan while you are healthy precisely so that it is still there when you are not.
Common questions about the unlimited-copay PPO
What is the unlimited-copay PPO (the "Cadillac plan")?
It is a private, medically underwritten health plan where in-network care runs on copays instead of coinsurance. You pay a set dollar amount for the visit, the lab, the surgery, even the hospital stay, and the plan pays the rest. Hospitalized for a month? Still the copay. It comes with unlimited doctor days, unlimited hospital days, and unlimited cancer treatment on a nationwide PPO network. It is sold outside the marketplace, so there is no income test, but you do have to qualify medically.
How is the Cadillac plan different from a marketplace (Obamacare) plan?
Three big ways. First, cost sharing: most marketplace plans use coinsurance, a percentage of the bill, for the expensive stuff. The Cadillac plan caps in-network care at copays. Second, the deductible: this plan has one deductible whether you are in or out of network, while many plans double it the moment you leave the network. Third, pricing: marketplace plans are priced by community rules and income subsidies, while this plan is priced on your health. If you are reasonably healthy, that usually works in your favor. If you get a large subsidy, the marketplace may still win. Compare both before deciding.
Who qualifies for the unlimited-copay PPO?
Reasonably healthy people and families. The plan is medically underwritten with a health look-back, so a recent serious diagnosis usually means a decline. In that case the guaranteed-issue marketplace is the honest answer for now, and the private market can be revisited later. These plans also do not cover certain medication categories, like ADHD stimulants and sleep medications, so people who depend on those should price them cash-pay before deciding. A good broker checks your doctors, your medications, and your health history against the plan before you apply.
Why has no broker ever shown me this plan?
A few reasons. Captive agents can only sell their own company's products, so they cannot show you what they do not carry. Marketplace enrollment is the default path, and it takes minutes, while an underwritten plan takes real work: checking doctors, medications, and health history for each person. And in community-rated states like New York, getting access takes an extra step through group rules that most agents never learned. None of that makes the plan a secret. It just means nobody was paid to explain it to you.
What does "no coinsurance" actually save me?
Coinsurance is a percentage of the bill, and on a hospital stay the bill is the scary part. With a typical 20% coinsurance, a $50,000 hospital bill can put you on the hook for $10,000, up to your plan's out-of-pocket maximum. On an unlimited-copay design, that same admission is capped at a set copay, whether you are there for two days or thirty. That is the whole point of the plan: the worst day of your year does not become a percentage problem.
Bring me your doctors, your medications, and what you pay now. I will check the network, run the health questions, and show you this plan next to your current one, real numbers side by side. If the marketplace wins, I will tell you that too. No hard sell, ever. I educate, you decide.
