Emergency Room Visits and Medicare: What You Pay in 2026

October 22, 2026

Older patient asking about an emergency room bill

Yes, Medicare covers emergency room care, but it does not cover all of it. If you are treated and sent home, Original Medicare bills the visit under Part B. In 2026 that means the $283 annual deductible, 20% of the Medicare-approved amount for doctor services, and a separate copayment for the hospital’s own services. If you are admitted, Part A takes over, and the math changes.

This guide walks through each scenario, explains the observation trap that surprises many Central Oregon seniors, and shows where supplemental coverage fits.

TL;DR

Part B usually covers emergency department services if you are not admitted. You pay the $283 deductible, then 20% of doctor services plus a hospital copayment.
If you are admitted as an inpatient, Part A applies, with a $1,736 deductible in 2026.
“Observation” is an outpatient status. Ask the hospital, in plain words, whether you are an inpatient or an outpatient.
Under federal law, a hospital that offers emergency services and takes Medicare must screen you whatever your coverage. Never delay care over cost.
Original Medicare has no out-of-pocket limit. A Medigap or Medicare Advantage plan is what changes that.

Does Medicare cover emergency room visits?

Medicare Part B (medical insurance) usually covers emergency department services. What you owe depends on what happens after you are examined: sent home, held for observation, or admitted.

Two points apply to every visit:

You do not need prior approval. Original Medicare does not require a referral to use an emergency room, and an emergency is by definition not something you can plan.
You cannot be turned away for lack of coverage. The Emergency Medical Treatment and Labor Act (EMTALA) guarantees a medical screening exam, and treatment until an emergency condition is stabilized. Hospitals that accept Medicare and offer emergency services must follow it, regardless of ability to pay.

So the first rule is simple: if you think it is an emergency, go. Sort out the billing afterward.

What you pay if you are treated and sent home

This is the most common case, and it produces the most confusing bills, because it is not one charge. It is several.

Charge	Who bills it	What you generally pay in 2026
Part B deductible	Applied to your first Part B costs of the year	$283 per year, if not already met
Doctor services in the ER	The emergency physician, often a separate group from the hospital	20% of the Medicare-approved amount, after the deductible
Hospital facility services	The hospital	A copayment for each outpatient service

The copayment for a single outpatient hospital service cannot be more than the inpatient hospital deductible. But a visit can involve several services, such as an exam, imaging, lab work and a procedure, so the copayments add up. Medicare’s own guidance warns that the total is hard to predict because it is the sum of separate charges, and that it can exceed a single Part A inpatient deductible.

That last point surprises people. Medicare pays its share, not 100%. Without supplemental coverage, there is no limit on what you pay out of pocket under Original Medicare.

A worked example

Suppose a hypothetical retiree in Bend slips on ice, goes to the ER with a wrist injury, gets X-rays and a splint, and goes home. She has already met her Part B deductible earlier in the year. She would typically owe:

20% of the approved amount for the physician’s exam and X-ray reading.
A hospital copayment for the ER visit, and possibly separate copayments for the X-ray and the splint.

The numbers are illustrative only, since actual amounts depend on the hospital and the services. What matters is the structure: a percentage on one side, copayments on the other, and no ceiling.

What you pay if you are admitted

If a doctor formally admits you as an inpatient, Part A pays for the hospital stay. In 2026 the Part A inpatient deductible is $1,736, up $60 from 2025. It covers your hospital services for the benefit period, and doctor services during the stay are billed under Part B.

There is a helpful rule here. If you are admitted within three days of the ER visit, most related outpatient services in those three days are rolled into the inpatient payment. That can spare you the separate outpatient copayments for the ER portion. Ask the billing office to confirm it was applied.

Three-day rule bundles related ER services inpatient

The observation trap

This is the part we most want you to know before you ever need it.

Being in a hospital bed does not make you an inpatient. Medicare says your status depends on a formal doctor’s order. If you are held “for observation,” you are an outpatient, even overnight. That means:

Your care is billed under Part B, with coinsurance and copayments, not under the Part A deductible.
For long observation stays, the outpatient charges can add up to more than the Part A deductible would have been.
Observation days do not count toward the three-day inpatient stay that Medicare requires before it covers care in a skilled nursing facility. Many people discover this only when the rehab bill arrives.

What to ask, and when

Ask these questions while you are still in the hospital:

“Am I an inpatient or an outpatient receiving observation services?”
“Has a doctor written an inpatient admission order?”
“If I’m in observation, who will review whether I should be admitted?”

Since February 14, 2025, if you were admitted as an inpatient and the hospital later changed your status to outpatient observation, you have the right to a fast appeal. A family member can ask these questions for you if you are too unwell.

ER, urgent care or a doctor’s office?

Not every problem needs an emergency department, and the cheaper venue can matter. A cut that needs stitches, a suspected urinary infection or a sprain may be handled at an urgent care clinic. Medicare Part B generally covers those services, though copays and any medications are on you, and the cost structure is usually simpler than a hospital’s separate physician and facility bills.

But do not use cost as a reason to hesitate with symptoms of a heart attack, stroke, serious bleeding, trouble breathing or sudden confusion. For those, call 911. In Central Oregon, distance matters too: if you live outside Bend in Sisters, La Pine or Prineville, the nearest emergency department may be a longer drive, which is one more reason to know your coverage before you need it.

How your coverage type changes the bill

The rules above describe Original Medicare on its own. Most people add something, and that choice decides how much of an ER bill lands on you.

Your coverage	How an ER visit is typically handled
Original Medicare only	Part B deductible, 20% of doctor services, hospital copayments, no out-of-pocket maximum
Original Medicare plus Medigap	A standardized supplement pays some or all of what Medicare leaves, depending on the plan letter
Medicare Advantage (Part C)	Your plan sets its own ER copay and out-of-pocket maximum, so read your plan’s Summary of Benefits

With Medigap, plan names are standardized, so Plan G from one company has the same benefits as Plan G from another, but premiums are not the same. If you are weighing options, our comparison of Medigap Plan G and Plan N explains how they differ in practice. You can also see an overview of Medicare Supplement plans.

With Medicare Advantage, the ER copay is set by your plan and is printed in its Evidence of Coverage. If your plan is not working for you, our guide to the Medicare Advantage disenrollment period lays out your options.

If an ER bill has made you realize your coverage has gaps, add-ons such as hospital indemnity insurance pay a cash benefit directly to you. Those are separate products with their own terms, so read them carefully.

Paying too much for Medigap? Oregon’s Birthday Rule

Many people we meet are already carrying a Medigap policy but have watched the premium climb year after year. Oregon offers a tool most states do not.

Under the Birthday Rule, you can switch to a different Medigap policy with the same or lesser benefits during a window of 30 days before to 30 days after your birthday, without medical underwriting. You cannot be denied because of your health history. The rule exists to prevent people from being trapped in a plan by rising premiums they cannot escape.

A few practical points:

Compare benefits and the insurer, not just the price. Plan letters match, but companies differ.
Do not cancel your old policy until the new one is confirmed. Many practitioners suggest a short overlap, even if it means two premiums for a month.
Switching from one Plan F High Deductible policy to another restarts the high deductible under the new carrier.

We cover the details in our guides to the Oregon Birthday Rule and how to switch Medigap plans. If you are newly eligible, Medigap guaranteed issue rights and the six-month open enrollment period may matter more.

Our perspective: plan for the bill before the ambulance

We are a local agency in Bend, and the ER conversations we have are rarely about the emergency itself. They are about the letter that arrives a few weeks later. Someone was kept overnight, assumed it was a hospital stay, and then learned it was observation. Someone else had a perfectly good Medigap plan but was paying far more than they needed to.

Our view is that the time to understand this is on a calm Tuesday, not in the waiting room. Know whether you have Original Medicare with a supplement or an Advantage plan. Know what your ER copay or coinsurance is. Keep your plan card in your wallet. And review your coverage every year, because premiums, plan networks and your own health change.

We do not push a particular plan. Our job is education first: explain how the parts fit, show you what an ER visit would cost under each choice, and let you decide. Because we are paid by carriers only when someone enrolls, we say plainly that a consultation is free and that you are welcome to take what you learn and decide elsewhere.

Start with our Medicare enrollment assistance, or book an annual Medicare plan review to see whether your current plan still fits. Consultations are free.

After an ER visit: a short checklist

Keep every document. Hospital discharge papers should state whether you were an inpatient or outpatient.
Read your Medicare Summary Notice. It arrives quarterly and lists what was billed. Compare it with the hospital’s and doctor’s bills.
Expect more than one bill. The ER physician group often bills separately from the hospital.
Call your supplemental insurer. Confirm what it paid and what remains.
Question anything unclear. Ask the billing office to explain each line. If you believe your status was handled wrongly, use the appeal rights described above.
Check for excess charges. Some providers who do not accept assignment can bill above the Medicare-approved amount. Our guide to Medicare excess charges explains when this applies.

FAQ

Does Medicare pay 100% of emergency room visits?

No. Under Part B you generally pay the deductible, 20% of doctor services, and hospital copayments. Medicare pays its share only. A Medigap policy can cover some or all of the rest, depending on the plan.

Does the emergency room take Medicare?

Hospitals that participate in Medicare and offer emergency services must screen and stabilize anyone who comes in, whether or not they can pay. Individual doctors who staff the ER may bill separately, so ask about their participation afterward, not before treatment.

What is the Medicare ER copay in 2026?

There is no single figure. Under Original Medicare, the hospital charges a copayment for each outpatient service, and a single service’s copayment cannot exceed the inpatient deductible, which is $1,736 in 2026. Medicare Advantage plans set their own ER copay, so check your plan documents.

Is an observation stay the same as being admitted?

No. Observation is an outpatient status billed under Part B, and it does not count toward the three-day inpatient stay needed for skilled nursing facility coverage. Ask your care team whether a doctor has written an inpatient order.

Can I switch Medigap plans after an ER visit?

Not freely. Outside of special situations, a new insurer can ask health questions. Oregon’s Birthday Rule gives you a yearly window around your birthday to switch to the same or lesser benefits without underwriting.
