What New: April 2026

When I wrote Your Hospital Bill Survival Guide, I wanted to give you the tools to fight back against confusing hospital bills. The system was already complicated. But a lot has changed in just the past few months, and some of it affects you right now.

Here's what you need to know.

Your Insurance Company Now Has to Show Its Homework

This is actually good news.

Starting March 31, 2026, insurance companies have to post public data on how often they say no to prior authorization requests. If you have not heard that term before, here is what it means. Prior authorization is when your doctor has to ask your insurance company for permission before you can get a test, a procedure, or a medicine. The insurance company decides whether they think you actually need it. If they say yes, you can move forward. If they say no, you have to fight it.

Before this new rule, you had no way of knowing whether your insurer said no to a lot of people or almost nobody. That information was kept private. Now they have to post it on their website for anyone to see.

The data also shows how fast they make decisions and how often they change their answer when someone pushes back. That second number is very important. More than 8 out of 10 appeals in Medicare Advantage get overturned. What that means is that if your insurance company says no to something, and you fight it, you have a really good chance of winning.

A lot of people do not appeal because they do not think it is worth the effort. This data shows that it is.

What you can do: If your insurance denies something your doctor ordered, do not just accept it. Ask for the denial in writing and then file an appeal. The book walks you through how to do that. The odds are in your favor.

Your Doctor Has to Get a Faster Answer Now Too

Also starting in 2026, most insurance plans have to give your doctor an answer on a standard prior authorization request within 7 days. For urgent situations, they have to respond within 72 hours.

Before this rule, they had up to 14 days to respond. That might not sound like a big difference. But when you are sick and waiting for approval to see a specialist or get a scan, those extra days feel like forever. And in some cases, waiting longer can mean your condition gets worse.

This rule applies to Medicare Advantage, Medicaid, and CHIP plans. It does not yet apply to ACA marketplace plans, which are the plans people buy through Healthcare.gov.

AI Is Now Making Decisions About Your Care

Here is something that should get your attention.

The government started a pilot program called WISeR. That stands for Wasteful and Inappropriate Service Reduction. It is running in 6 states right now. The idea behind it is to use artificial intelligence to help decide whether Medicare patients should get certain medical treatments.

Artificial intelligence, or AI, is a computer program that learns from patterns in data and then makes decisions based on those patterns. You may have heard of programs like ChatGPT. This is a similar idea, but instead of answering questions about recipes or history, it is looking at your medical information and deciding whether you should get care.

In Texas, where this program is already running, the AI said no to 38% of requests at first. But when a real human being reviewed those same decisions, they changed the answer to yes 84% of the time.

That means the computer was wrong a lot. And while those appeals were being reviewed, patients were waiting to get care they needed.

A nonprofit civil rights organization has already sued the government to get more information about how this AI makes its decisions. As of right now, the public does not know much about how the program works or how it was trained.

What you can do: If you are on traditional Medicare and a prior authorization is denied, ask whether a human being reviewed your case. You have the right to appeal and have a real person look at your situation. Do not assume the first answer is the final answer.

AI Is Also Writing Your Bill, and It May Be Making It Bigger

This one surprised me when I first read about it.

Many hospitals are now using AI tools to help doctors take notes during your visit. The doctor talks, the AI listens, and it writes up the clinical notes automatically. The idea is to save the doctor time so they can focus more on you instead of typing.

That part sounds helpful. But here is the problem.

Those clinical notes are also what determines how your visit gets billed. The more detailed and complex the notes, the higher the billing category your visit gets assigned to. Higher billing category means a higher charge.

These AI tools write very detailed notes. And a new research report found that as a result, hospitals are billing for more complex visits than they used to. This is sometimes called upcoding, which means assigning a higher billing code than the visit actually calls for.

This matters for you because higher charges can mean higher costs, depending on your insurance and your deductible. Insurance companies are starting to notice and push back by paying out less. But for now, bills may be going up because of this.

What you can do: If you get a hospital bill that seems higher than you expected, you still have the right to ask for an itemized bill. That is a line-by-line list of every charge. Review it carefully. If something looks wrong or does not match what actually happened during your visit, you can dispute it. The book walks through exactly how to do this.

Big Medicaid Cuts Are Coming

Last summer, Congress passed a law called the One Big Beautiful Bill Act. The name sounds lighthearted. The effects are not.

This law cuts Medicaid funding significantly over the next 10 years. It also adds a new requirement that starts in 2027. If you are between 19 and 64 years old, you will need to prove to your state that you are working, going to school, or volunteering at least 80 hours a month in order to keep your Medicaid coverage.

That might sound simple enough. But the paperwork involved in proving that every month is complicated, and many people who do qualify will lose coverage simply because they do not know how to navigate the process or miss a deadline.

We already have a real-life example of what happens. Georgia tried a similar program a few years ago. The result was that people lost their Medicaid coverage, but the number of people with jobs did not go up. The state ended up spending twice as much money on the paperwork and administration as it spent on actually helping people get care.

On top of the Medicaid changes, Congress is also in early discussions about cutting the financial help that makes ACA marketplace plans affordable. These are the subsidies that lower your monthly premium if you buy insurance through Healthcare.gov. If those get cut, some people may no longer be able to afford their plans.

What you can do: If you are on Medicaid, pay close attention to any mail or notices from your state. Do not throw them away or set them aside. If you get a notice saying your coverage is changing or that you need to verify your eligibility, respond right away. Missing a deadline could mean losing your coverage.

If your coverage does change and you end up uninsured, remember that nonprofit hospitals are still required by law to offer financial assistance. That has not changed. The book's chapters on charity care and financial assistance programs still apply.

Some New Tools That May Help You

Not everything happening right now is bad news. A few new tools launched this spring that are worth knowing about.

UnitedHealthcare launched an AI assistant called Avery. It is available through their app and website. You can ask it questions about your benefits, find out the status of a claim, get an explanation of your coverage, and it can even call your doctor's office to schedule an appointment on your behalf. It is available to some members now and will expand to more members throughout 2026.

The government agency that runs Medicare and Medicaid, called CMS, also launched a set of new digital tools. These tools are designed to let patients pull up their health records on their phone and share them with a doctor using a QR code, which is one of those square barcodes you scan with your camera. The goal is to replace the stack of paper forms you fill out every time you go to a new doctor.

These tools will not solve your billing problems on their own. But anything that helps you understand your coverage before you receive a bill is a step in the right direction. And tools that make it easier to share your medical history can help prevent duplicate tests and procedures, which means fewer unnecessary charges.

The Bottom Line

The hospital billing system has not gotten simpler since I wrote the book. If anything, there are more things to keep track of now. AI is making decisions about your care, new rules are changing how quickly your insurance has to respond, and big political changes are coming for Medicaid and ACA coverage.

But the core advice in the book still holds.

Ask for an itemized bill. Ask about financial assistance, because every nonprofit hospital is required to offer it. Do not ignore a denial. Appeal it. Talk to a financial counselor at the hospital. And never be embarrassed to ask for help.

The system is set up in a way that makes it easy to give up. Do not give up. You have more options than you think.
