Medicare, the ACA and Pennie, explained

Three names that get used as if they meant the same thing. They do not. This page explains what each one actually is, without naming a single plan or quoting a single price, so you can work out which system you are in before anyone tries to sell you anything.

Three names, three different things

Medicare, the ACA and Pennie get used interchangeably and they are not interchangeable. One is a program, one is a law, and one is a website run by the Commonwealth. Knowing which is which tells you where to go.

A federal program

Medicare

Health coverage run by the federal government, mainly for people 65 and older, and for some younger people with qualifying disabilities. You enroll through Social Security and the federal Medicare program. Pennie has nothing to do with it.

A federal law

The Affordable Care Act

A 2010 law, not a plan you can buy. It set the rules that individual health coverage has to follow, including no denials for pre-existing conditions and a required set of benefit categories, and it created the marketplaces and the financial help that go with them.

Pennsylvania's marketplace

Pennie

The marketplace where Pennsylvanians actually buy ACA coverage. Pennie replaced HealthCare.gov for Pennsylvania residents and is the only place in the state where you can use a premium tax credit to lower what you pay.

Medicare

Medicare, in the order it actually makes sense

Medicare is usually explained as four letters. What matters more is that there are two ways to receive it, and the letters describe pieces of those two routes.

Who it covers

People 65 and older, people under 65 who have received Social Security disability benefits for 24 months, and people with end-stage renal disease or ALS. Turning 65 does not enroll you automatically unless you are already drawing Social Security.

Part A: hospital insurance

Inpatient hospital stays, skilled nursing facility care after a qualifying stay, hospice, and some home health care. Most people qualify without an additional monthly premium because they paid Medicare taxes while working.

Part B: medical insurance

Doctor visits, outpatient care, preventive services, lab work and durable medical equipment. Part B carries a monthly premium that most people have deducted from their Social Security payment; people with higher incomes pay more.

Part C: Medicare Advantage

A way of receiving your Medicare through a private plan approved by Medicare, instead of directly from the government. These plans bundle Part A and Part B, usually add drug coverage, and typically use provider networks and prior authorization rules that Original Medicare does not.

Part D: prescription drug coverage

Sold by private insurers, either as a standalone drug plan alongside Original Medicare or built into a Medicare Advantage plan. Each plan publishes its own list of covered drugs, and that list can change from year to year.

Medicare Supplement, sometimes called Medigap

A separate category of private policy that pays some of the costs Original Medicare leaves to you. Medigap works only alongside Original Medicare and cannot be combined with a Medicare Advantage plan. Modern Medigap policies do not include drug coverage, so a Part D plan is bought separately.

Original Medicare or Medicare Advantage: how are they different?

They are two routes, not two products from the same shelf. With Original Medicare you use Part A and Part B directly from the federal government, see any provider in the country who accepts Medicare, and typically add a Part D drug plan and often a Medicare Supplement policy. With Medicare Advantage a private plan administers your Medicare, usually inside a network, generally with drug coverage included and a yearly limit on what you pay out of pocket. Which fits depends on your doctors, your prescriptions, how much you travel, and how you feel about networks and prior authorization. There is no version of this question that has the same answer for everyone.

Do I have to sign up at 65 if I'm still working?

Not always. If you have coverage through your own or a spouse's current employer, and that employer is large enough for the rules to apply, you can usually delay Part B without penalty and pick it up later through a special enrollment period. Retiree coverage, COBRA and marketplace coverage do not count as current employer coverage for this purpose, and treating them as if they do is one of the more expensive mistakes people make. Medicare publishes the specifics.

What is the late enrollment penalty?

If you delay Part B or Part D without a qualifying reason, Medicare adds a surcharge to your premium, and for Part B it generally stays on your premium for as long as you have the coverage. The amount grows with how long you waited, which is why the seven-month window around your 65th birthday matters even to people who feel healthy.

What if I can't afford my share of the costs?

Two federal programs exist for that. Extra Help lowers what you pay for prescription drug coverage, and Medicare Savings Programs, administered in Pennsylvania through the state, can help with Part B premiums and other costs. Both have income and resource limits and both are applied for, not automatic. PA MEDI counselors will help you check eligibility at no charge.

Does Medicare cover long-term care?

Broadly, no. This is the single most common misunderstanding about the program. Medicare pays for short skilled nursing stays after a qualifying hospital admission, not for ongoing custodial care such as help with bathing, dressing or eating. That is covered by long-term care insurance, by personal funds, or, for those who qualify financially, by Medical Assistance.

The Affordable Care Act

What the law actually changed

The ACA is a set of rules that individual and small-group coverage has to follow. You do not buy 'an ACA plan'. You buy a plan that has to obey the ACA.

Coverage cannot be denied for health reasons

Insurers cannot refuse you, exclude a condition, or charge you more because of your medical history. Before the ACA, individual coverage was medically underwritten and a diagnosis could make it unavailable at any price.

Ten categories of benefits are required

Every compliant individual plan has to cover ten essential health benefit categories, including hospitalization, prescription drugs, emergency services, maternity and newborn care, and mental health and substance use treatment. What sits inside each category still varies by plan.

Preventive care is covered without a separate charge

Most plans have to cover a defined list of preventive services, including screenings, immunizations and annual wellness visits, without charging you separately for them when you use an in-network provider.

Metal categories describe cost sharing, not quality

Bronze, Silver, Gold and Platinum describe how you and the plan divide costs, not how good the care is. A Bronze plan generally means lower monthly cost and more paid when you use care; Platinum is the reverse. The metal level says nothing about the doctors in the network.

Financial help is tied to income

The premium tax credit lowers what you pay each month and is based on your projected household income for the coverage year, measured against the federal poverty level. It is reconciled on your tax return, so an income estimate that turns out to be badly wrong is settled later, in either direction.

Cost-sharing reductions are Silver-only

A second, separate kind of help lowers your deductible and what you pay at the point of care. Unlike the premium tax credit it is available only if you enroll in a Silver plan and your income falls in the qualifying range, which is why the cheapest-premium plan is not automatically the cheapest plan.

Did the extra subsidies from recent years go away?

Yes. Temporary enhanced premium tax credits were in place from 2021 through 2025. Congress let them expire at the end of 2025, so from 2026 onward the original ACA rules apply again, including the cutoff at 400% of the federal poverty level, often called the subsidy cliff. Earning a dollar over that line can end premium assistance entirely, which makes an accurate income estimate more consequential than it used to be. The IRS and HealthCare.gov publish the current rules.

What is the federal poverty level and why does it decide anything?

It is an income figure published each year by the federal government, adjusted for household size. Eligibility for the premium tax credit, for cost-sharing reductions, and for Medical Assistance are all expressed as percentages of it. Because it moves annually and depends on how many people are in your household, the same income can qualify one year and not the next.

My employer offers coverage. Can I use Pennie instead?

You can always buy through Pennie, but if your employer offers coverage that the law considers affordable and adequate, you generally cannot receive a premium tax credit, which usually makes the marketplace the more expensive route. Whether an offer counts as affordable is a specific calculation, not a judgment call, and it is worth checking rather than assuming.

What if my income is low?

Pennie checks that for you. If your household income falls low enough, the application routes you toward Medical Assistance, Pennsylvania's Medicaid program, or toward CHIP for children, rather than a marketplace plan. Those programs enroll year-round, with no open enrollment window.

Pennie

Pennsylvania's own marketplace

Pennie is run by the Commonwealth, not by an insurance company and not by the federal government. It is where the ACA rules and Pennsylvania residents meet.

It replaced HealthCare.gov for Pennsylvania

Pennsylvania created its own state-based marketplace under Act 42 of 2019 and moved off the federal website. Pennsylvanians shopping for individual coverage now use Pennie instead of HealthCare.gov.

It is the only door to the tax credit

You can buy individual health coverage directly from an insurer in Pennsylvania. But a premium tax credit can only be applied to a plan bought through Pennie. Buy off-marketplace and you pay the full premium regardless of your income.

Help through Pennie is free either way

Pennie certifies both brokers and assisters. Assisters are grant-funded and cannot sell you anything. Brokers, including this agency, are paid a commission by the insurer whose plan you choose, never by you, and never at a higher premium than you would pay enrolling on your own.

It connects to the other programs

A single Pennie application checks your household against Medical Assistance and CHIP as well as marketplace coverage, so a family whose members qualify for different programs does not have to apply in three places.

Path to Pennie

Pennsylvania added a box on the state tax return for uninsured filers. Check it and Pennie follows up with an eligibility estimate and a special enrollment opportunity, a route into coverage that has nothing to do with the normal calendar.

Does a plan cost more if I use a broker?

No. Premiums for marketplace plans are set by the insurer and filed with the Pennsylvania Insurance Department. The same plan is the same price whether you enroll yourself on Pennie, work with a free assister, or work with a certified broker. What differs is who helps you compare, not what you pay.

Can I be on Medicare and a Pennie plan at the same time?

This is the trap worth knowing about. Once you are eligible for Medicare Part A without a premium, you generally cannot receive a premium tax credit for a marketplace plan, and keeping one anyway can leave you paying full price for coverage that duplicates what Medicare already does. If you are approaching 65 with a Pennie plan, this is the conversation to have before your birthday, not after.

What if I move out of Pennsylvania?

A Pennie plan follows Pennsylvania residency. Moving out of state is itself a qualifying life event, and you would enroll through your new state's marketplace or through HealthCare.gov. Moving within Pennsylvania can also change which plans are available to you, because networks and plan availability are set county by county.

Which one is yours?

A rough map, not a recommendation

This is orientation, enough to know which system you are dealing with and which official source to read. It is not advice about your situation, and nobody should treat it as such.

Under 65, buying your own coverage

Pennie

This is the main case the ACA marketplace was built for. Start a Pennie application; it will tell you what financial help you qualify for.

Turning 65 in the next year

Medicare

Your seven-month initial enrollment window opens three months before your birthday month. If you are on a Pennie plan now, sort out the transition before the window closes.

Under 65 but on Social Security disability for 24 months

Medicare

Medicare eligibility is not only about age. Enrollment is generally automatic at the 25th month.

Offered coverage at work

Usually your employer's plan

If the offer is considered affordable under the law, a premium tax credit is generally off the table, which usually makes the employer plan the cheaper route even when the plan itself is unremarkable.

Income is low, or you have children

Medical Assistance or CHIP

Pennsylvania's Medicaid program and CHIP enroll year-round. A Pennie application screens for both automatically.

Between jobs, or just lost coverage

Pennie, on the clock

Losing coverage opens a special enrollment period, generally 60 days from the date it ends. That clock runs whether or not you have decided what to do.

No strings

Free, unbiased help that isn't us

We are a broker, and a broker earns a commission when you enroll. These organizations do not, and every one of them will help you for nothing. Use them before, instead of, or alongside talking to us.

Independent help in Pennsylvania

PA MEDI counselors are trained by the Commonwealth and sell nothing at all.

Read all this and still want a second pair of eyes?

That is what a consultation is for. We will go through your doctors, your prescriptions and what is changing next year, and tell you plainly where the trade-offs are. No charge, and no obligation to buy anything.
