What health insurance does not cover, and what does.
No single policy was ever built to catch everything. A health plan is the foundation, and it is a good foundation — but it stops in several specific places, and each one of those is where another layer gets built on top of it. This page shows what every layer does, where it stops, and which one to add first. Nothing here is a pitch for buying all of them. Most people should not.
The middle is your health plan or Medicare. Each ring around it covers something that plan was never built to handle — teeth and eyes, the part of a big bill that is still yours, a wrong bill nobody will fix, and your paycheck if you cannot work. Tap a ring to see what it does.
Everything that stands between you and a medical bill
Read it from the middle out. The circle in the center is the foundation — the one almost everybody needs first — and every ring around it is a layer built on top, covering something the foundation was never meant to handle.

Meet Jane. She is made up, not a real client. Each layer below ends with one month of her year — an example of how that layer actually plays out for someone. Nothing that happens to her is unusual.
•The middle — your main health plandoctors, hospital, prescriptions
What it doesPays the big ones — doctors, the hospital, prescriptions, the emergency room — and caps what a bad year can cost you.
Almost everybody needs this one, and it is the only part of the wheel that is not optional. Some people get it through a job, some buy their own, and others move onto Medicare when the time comes. Different routes, same job — and nothing in a ring is worth looking at until this part is right.
In practice · Jane in JanuaryJane is 41. She cuts hair in a chair she rents at a shop downtown, so nobody hands her benefits — she has to go buy them. Her own health plan starts on New Year’s Day. It covers doctors, hospital and prescriptions, and it caps her worst year at the plan’s out-of-pocket maximum, the most she can be asked to pay in one year. She feels covered, and for doctors she is. It does not touch her teeth, her eyes, or a single dollar of what she earns.
Where it stopsat your deductible, your share of the bill after it, and your out-of-pocket maximum — which is the real number to know, because it is what a bad year costs you.

1What it ignoresteeth and eyes
What it doesPays toward cleanings, fillings, crowns, eye exams and glasses — the things a medical plan was never built to cover.
A health plan covers doctors, hospital and prescriptions. It was never built to cover your teeth or your eyes — so a cleaning, a crown or a pair of glasses is a bill you pay in full unless you have something for it. This is the cheapest ring to fill and the one people put off longest.
In practice · Jane in FebruaryJane bites down on a popcorn kernel and cracks a molar. The crown is the full price, because a medical plan was never built to cover teeth. Nothing went wrong with her health plan — this was simply never in it. A dental plan pays a share, up to that plan’s annual maximum, the most it will pay out in a year. Jane puts the crown on a credit card.

2What it leaves youthe part of a big bill that is still yours
What it doesPays cash straight to you after an injury or a hospital stay, and you spend it on whatever the real cost turns out to be.
Everything here is covered. You still pay a share of it. Even a good plan hands you the first few thousand dollars of a hospital stay, on top of what you already pay every month. This ring is money paid straight to you after an injury or a stay — and you spend it on whatever the real cost turns out to be, including the rent and the driving.
In practice · Jane in MayJane slips on a wet floor at the shop and spends three nights in the hospital. The stay is covered, and she still owes her deductible first, then her share of what is left, called coinsurance, until she reaches that out-of-pocket maximum. A hospital indemnity plan would have paid her cash for each of those three days — money for the parking, the gas, and the week her husband took off work to drive her.
Where it stopsit pays on specific events, so it does nothing for an ordinary year of ordinary care.

3When it goes wronga wrong bill, or a no that should have been a yes
What it doesPuts a person on your side to fight a wrong bill or a denied claim, so you are not the one on hold.
This one is not about coverage at all. It is about the times they say no when they should have said yes, or a bill turns up that nobody can explain. Both happen far more often than people expect, and almost nobody pushes back — because it means hours on hold while you are already unwell. This ring is having someone who does it for you.
In practice · Jane in JuneA bill arrives from a doctor Jane never met, coded out of network. He is the radiologist who read her X‑ray at an in‑network hospital, so the bill is wrong — but it still counts as a claim denial, and the only way back is an appeal: forms, deadlines, and a morning on hold while she is still healing. No policy on this page pays this one. It takes somebody who makes that call for her.
Where it stopsit is a service, not a policy — it pays no part of any bill, and free routes exist for a one-off problem.

4When you cannot workthe money you earn, if it stops
What it doesReplaces part of your paycheck while you are too sick or too hurt to work, so the rent still gets paid.
Every ring inside this one assumes the money keeps arriving. A health plan pays the doctor — it never pays you. If an illness or an injury keeps you out of work for months, the rent and the groceries do not pause, and this is the only thing on the wheel that replaces the paycheck itself.
In practice · Jane in JulyJane cannot stand at a chair for eight hours yet, so for seven weeks she does not work. Short-term disability would have replaced part of her income, but not from day one: payments start after the elimination period, the waiting days written into the policy. The hospital got paid. Jane did not. Her rent did not care either way.
Where it stopsit pays a share of your income, not all of it, and usually only after a waiting period — so it buys you months, not a permanent income.

+Outside the wheelmoney for your family, and money for retirement
What it doesLeaves money for the people who depend on you, and builds money you can live on after you stop working.
Money for the people who depend on you, and money for later. Both are real, and neither one is foundation. They do their job once the four rings are in place, and they are a poor substitute for them.
In practice · Jane, afterwardJane came home. Every layer above assumed she would — life insurance is the one that does not, and it is the one her husband would have been left leaning on. An annuity is the same idea pointed at retirement instead: money that keeps arriving after the paychecks stop for good.
Where it stopsit pays nothing while you are alive, which is exactly why it is not a substitute for the layer that replaces your income — and why buying it first is the most common mistake on this page.

The most expensive mistake is buying these out of order
Almost every expensive mistake people make here is something bought out of order. A cancer policy before a health plan. A hospital cash plan protecting a deductible on coverage that does not exist. Burial coverage sold to someone whose income stops the week they do.
The order is always the same, and it is the order of the rings: the health plan first, then teeth and eyes, then cash for a hospital stay, then someone to fight a wrong bill, then your paycheck. A health plan or Medicare is the one thing on the list that can end your finances outright, and until that is right nothing around it is worth buying. Once it is right, the rest is a question of what would actually hurt you, not what is available.
And if the middle is out of reach? That is a more common question this year than last, and it does not change the order — it changes what goes in the middle. Most people who believe they have nothing still have something: a subsidy nobody re-checked, a catastrophic plan, or Covered Connecticut. And if you do end up with something that is not insurance in the middle, such as a health share, the rings around it do more work, not less — because nobody is legally required to pay a health share bill, so the middle is thinner than it looks.

How to read your own situation
Three numbers tell you most of it, and you already have all three. Your out-of-pocket maximum is on your plan documents, and it is what a genuinely bad year costs you. What three months without pay would do to you is a number only you know. What you have saved is the third. Put them side by side and the gaps name themselves.
If your savings would absorb your out-of-pocket maximum without drama, ring two — the money paid straight to you — is a convenience rather than protection. If three months without pay would end your housing, ring four — your paycheck — is not optional. That is the whole analysis, and it takes about five minutes with someone who does it every day.
Where you live changes part of this too, because the rules and the deadlines are not the same in every state. The state-by-state page has that part.
Common questions about what is and is not covered
Tap the one that sounds like you.
What does health insurance not cover?
Four things, reliably. Your own share of the cost — the deductible, the copays and the coinsurance, up to your out-of-pocket maximum. Routine dental and vision for adults, which sit almost entirely outside a medical plan. Anything judged not medically necessary, which is where most denials live and where most appeals are won or lost. And your income, which stops when you cannot work and which no health plan has ever replaced. The first is budgeted for, the second and third are bought separately, and the fourth is what disability coverage is for.
In what order should I buy insurance coverage?
Build outward from the middle of the wheel, and the order rarely changes. A health plan or Medicare first, because one hospital stay without it is the only thing on this list that can end your finances outright. Then teeth and eyes, which are the cheapest to cover and the most used. Then the gap products that hand you cash after a hospital stay or a serious diagnosis. Then someone in your corner when a bill is wrong or a claim is denied. Then what replaces your paycheck if you cannot work for months. Money for your family and money for retirement last. A policy bought out of order is usually paying for a small risk while a large one sits uncovered, and that is the single most common thing worth fixing on a first conversation.
Do I need all of these kinds of coverage?
Almost certainly not, and anyone telling you otherwise is selling rather than advising. Most households need the first layer done properly and one or two above it, chosen for their own situation — a young self-employed person and a retired couple have almost nothing in common here. The point of this page is not to lengthen the list. It is so that when you decide to skip something, you are skipping it on purpose rather than because nobody mentioned it.
What is an out-of-pocket maximum, and why does it matter more than the premium?
It is the most you can be made to pay in a plan year for covered care, after which the plan pays everything. The premium is what a normal year costs you; the out-of-pocket maximum is what a bad year costs you, and a bad year is the thing you are insuring against. A cheaper premium with a much higher out-of-pocket maximum is not a cheaper plan — it is a bet that this year will be ordinary. That bet is fine if your savings could absorb the difference, and expensive if they could not.
Does coverage cost more if I use an agent?
No. The plan costs the same whether you enroll on your own or with help, because the carrier pays the commission either way — which is also why there is no reason to steer you toward one thing over another. If the right answer for you is the plan you already have, or nothing at all, you will be told that.
Is hospital indemnity insurance worth it?
It comes down to one comparison: what your plan would make you pay in a genuinely bad year, against what you could absorb without borrowing. If your out-of-pocket maximum is a number you already have sitting in savings, a hospital indemnity policy is a convenience. If that number would end up on a credit card, the policy is doing real work. It pays a fixed amount per day or per event rather than paying the bill, so the comparison worth making is that payout against the gap you actually have — not against the premium.
What is the difference between hospital indemnity and critical illness insurance?
Both pay cash to you rather than paying a provider, and that is where the similarity stops. Hospital indemnity pays on an event — a night admitted, an ambulance, an intensive care stay — and pays again the next time one happens. Critical illness pays once, as a lump sum, when you are diagnosed with something on a named list, usually cancer, heart attack or stroke. One is tied to being admitted, the other to being diagnosed. People often carry both because they fire at different moments.
What is the difference between critical illness and disability insurance?
Critical illness pays a lump sum on a diagnosis, whether or not you miss a single day of work. Disability pays a share of your income, month after month, for as long as you cannot work — and pays nothing if you can. One is a check for the diagnosis; the other is a stand-in for the paycheck. That is why they sit in different rings on this page rather than next to each other.
Do I really need dental insurance if I have health insurance?
A medical plan almost never covers routine dental for adults, so cleanings, fillings and crowns are yours. Whether a separate dental plan earns its premium comes down to three numbers: the annual maximum, the waiting period, and what you realistically expect to need. Someone with a crown ahead of them is in a different position from someone who has had two cleanings a year for a decade and nothing else.
What goes in the middle if I do not qualify for Obamacare or Medicare?
This is the question of the year, and the honest answer has two halves.
Most people who believe they have nothing still have something — a subsidy that was never re-checked, a catastrophic plan they did not know they could buy, or Covered Connecticut. A real plan in the middle is always worth more than anything you can wrap around an empty space.
And if you genuinely end up with something that is not insurance in the middle, such as a health share, the rings around it do more work, not less. Nobody is legally required to pay a health share bill, so the middle is thinner than it looks, and the cash-paying layers and the help with a wrong bill stop being optional extras. See every option when the middle is out of reach.
The middle is a plan through work. Does that change the order?
Not the order, but it changes who is in the middle. A group plan through work is a real foundation and it belongs in the center. The thing people miss is that the household does not have to share one middle. If the plan at work is affordable for the worker and far out of reach for the family, the worker stays there and the family can sit on a subsidised marketplace plan instead — two foundations, one household, and the rings go around both. How the work-plan test decides this.
