Your Crohn's Infusion Costs More in the Hospital

The same infusion drug can carry a different bill depending on where you receive it.

If you get Crohn's infusions, you may have wondered why your bill looks so different from what someone else pays for the very same drug. That worry is common. You are not imagining it. It can help to keep your last few infusion statements close by as you read.

A 2026 study in the Journal of Managed Care & Specialty Pharmacy looked at 23 infusion drugs used for long-term conditions such as Crohn's disease, and it found that hospital outpatient departments cost more without fewer side effects, fewer ER trips or better adherence. The same paper pointed to earlier survey work showing that over two-thirds of people with immune-related conditions did not have a choice of infusion site. Many people are never asked.

One caveat matters here. The research has limits, and the section below spells them out. Still, the reason behind the gap reaches Medicare too. Your gastroenterologist can tell you whether your treatment needs a hospital setting at all. Home infusion has its own gaps under Medicare, so it is not an automatic answer either.

So it helps to start with where the extra dollars on a hospital bill actually come from.

Where does the extra money on a hospital infusion bill come from?

The extra money comes from the building, not the medicine. A hospital outpatient department can add a facility fee and its own administration charge to the very same Crohn's drug.

Before you look at any study, it can help to pull out your last statement and check three things:

1. Find the place of service. Does it say hospital outpatient department, doctor's office or infusion center?
2. Look for a separate facility charge sitting next to the drug line.
3. Note the drug line on its own, so you can compare it with what an office would bill for the same product.

A 2026 study from the Elevance Health Public Policy Institute found that outpatient costs within one day of an infusion were 41.9% higher in hospital outpatient departments than at infusion centers, homes and doctors' offices. The researchers matched 52,760 infusions among 18,988 patients, and Crohn's disease was one of the seven conditions they studied. Same drugs. Different bills.

So where does the gap live? A 2023 paper in the journal Pharmacy explained that a hospital outpatient department can charge both a facility fee and an administration fee for a medication, which a non-hospital site cannot. In 2023, those authors put the total cost difference between the two settings at 80 to 150%. They also noted that freestanding and physician infusion clinics typically charge at or near Medicare's allowable rate, called ASP + 6%. ASP means average sales price, so that rate is the drug's average price plus a small 6% add-on.

Here's the thing. A facility fee does not buy a better drug or a different dose. It pays for hospital overhead, billed on top of the care itself.

One infusion center company argues that the same drug runs two to three times higher in a hospital, because hospitals bill facility fees while its centers bill only the administration code and the drug. That is the company's own sales claim, so it is best read as a pitch rather than a measured figure. Commercial prices widen the spread further: in 2022, private insurers paid roughly 267% of Medicare rates for hospital care on average.

The common assumption is that 20% coinsurance means the same thing wherever you sit. It does not. Combining 5 sources points to one pattern: the drug stays the same while the charges wrapped around it grow. In practice, your share follows the bigger total.

If reading these line items feels like a second job, you are not alone. Understood Care advocates are available in all 50 states, delivered virtually and covered by Medicare, and they can walk through a statement with you one line at a time. I wrote about a similar trap in our guide on why "Medicare pays 80%" misleads buyers, and the same percentage math shows up on infusion bills. The harder question many families ask next is whether the lower-cost chair is just as safe.

Is a lower-cost infusion center as safe as the hospital?

For most stable patients, the research shows similar safety at lower-cost sites. Some people still have good clinical reasons to stay at the hospital, and that choice deserves respect.

It's common to worry that leaving the hospital means giving up a safety net. That worry makes sense. You may have had a reaction before, or you may simply feel calmer near an emergency room.

The Elevance Health researchers looked at exactly this question. They found no significant differences in serious or mild adverse events between hospital patients and patients treated at infusion centers, homes and offices. Emergency room visits and hospital stays in the first day after an infusion were also similar. Among the 410 patients they checked for adherence, staying on treatment a year later looked the same at every site.

There is one caveat worth knowing. Within seven days of an infusion, the hospital group had 45.2% higher odds of an inpatient admission. That does not prove the hospital caused those stays. Sicker patients may simply be treated there more often, even after the matching the researchers did.

The study also left out any infusion where a hospital setting was judged medically necessary. That detail matters. The findings speak to stable patients, not to everyone.

Not every lower-cost site is the same, either. Earlier research the same authors cite linked home infusion of biologics to more emergency visits and admissions than physician offices for certain immune conditions. A doctor's office and your living room are different places.

Real patients weigh these trade-offs in personal ways. In a 2022 Reddit thread in r/CrohnsDisease, one person described pushing back when their insurer tried to move them to a cheaper preferred center. They wanted to stay at a hospital unit with a maximum 4:1 patient-to-nurse ratio, and their doctor was concerned about past infusion reactions. In a 2019 thread, another patient said they still felt safer at an infusion center "if something should go wrong." Home infusion companies, for their part, say most patients would rather be treated at home, though that is their own sales message.

I'd encourage you to treat safety as a conversation, not a coin toss. Questions that can help with your gastroenterologist include:

• Have I had an infusion reaction that changes where I should be treated?
• Is my current dose or speed something an office or center can offer?
• What would happen at a center if I reacted during a session?

If you'd like a second set of eyes on that conversation, our guide to choosing a Medicare patient advocate explains what an advocate can and cannot do for you. Once safety feels settled, the next step is finding out what your own site actually charges you.

How can you check what your infusion site costs you?

Start with your 2026 Part B numbers, a $283 deductible and a $202.90 monthly premium. Then ask your infusion site one plain question: how does it bill?

Those two figures come from the Centers for Medicare & Medicaid Services. Your premium stays the same wherever you sit. Your coinsurance is the part that moves, because it is a share of whatever amount the site is allowed to bill.

It can feel like a lot to take on between infusions. You can go at your own pace. These five steps are a good place to begin:

1. Call your infusion site's billing office. Ask whether it bills as a hospital outpatient department, a physician office or a freestanding infusion center, and whether a facility fee appears on your claims.
2. Ask the site for a written estimate of your share for one infusion, using your exact drug and dose.
3. Call the number on your Medicare card or plan card. Ask which nearby sites are in network and whether your drug needs prior authorization at a new site.
4. If you have a supplement (Medigap) plan, ask how it handles your Part B coinsurance at each type of site.
5. Bring what you learn to your gastroenterologist and ask whether an office or center is a good fit for you.

Hospitals themselves are starting to say this out loud. UC San Diego Health tells its patients that "where you get your treatment can affect your out-of-pocket costs," and it notes that its hospital-licensed infusion centers "may be associated with higher out-of-pocket charges." It encourages patients to talk with both their insurer and their provider before choosing.

That second point matters more than people expect. Some health plans say a drug's specialty status can limit where you are allowed to receive it, and that prior authorization is likely. A cheaper site only helps if your plan will pay for your drug there.

I wish I could hand you an average dollar savings from switching. Ask the person on the phone to send you an estimate for each site in writing, so you can compare them side by side. That is why step two is so useful.

If you are on a Medicare Advantage plan, site rules may look different from Original Medicare. Our look at whether plan extras are worth leaving Original Medicare walks through some of those trade-offs.

You do not have to make these calls alone. With Understood Care, while your advocate is actively working on your case, you'll hear from them every 7 days by phone, text or email with progress information. That rhythm helps when a billing office promises a callback and the week slips away. Keep each written estimate together, so the numbers are ready when you talk with your doctor.

What should you do before your next Crohn's infusion?

Ask where your infusion is billed before your next appointment. Write down your plan's answer for each site, with the date and the name of the person you spoke with.

This gap is unlikely to fade on its own. On a 2026 Advisory Board podcast, analyst Chloe Bakst said a little over half of infusions are delivered in hospital outpatient departments, and the share in Medicare is about the same. She added that commercial plans pay those hospital departments around 177% of the drug's average sales price, compared with about 120% in a doctor's office. Where infusions take place, in her words, "will likely be changing."

Here is what I can't tell you yet. No one has published side-by-side Medicare infusion bills across sites, and there is no reliable average for what a switch saves. If the numbers differ, bring them to your gastroenterologist and ask whether a lower-cost site would be safe for you.

So I'd start small. Call your plan. Keep the list of sites your doctor offers next to the phone. If it surprises you, that is a good moment to bring in some help.
