4 places rehabs lose insurance money they already earned (2026)

The short version

Most rehabs lose reimbursement they already earned in four places between care and cash: admitting without checking benefits, Medicaid coverage that lapses mid-treatment, notes that don't prove medical necessity, and underpayments and denials nobody fights. AI can't raise your rates, but each leak has an AI fix today, and a person still signs off on every decision.

Ten addiction treatment providers in California sued Cigna in August. Their complaint says they billed about $15.3 million in covered charges and got paid about $2.5 million. That's roughly 16 cents on the dollar (Healthcare Finance News, Becker's Payer). Those are the plaintiffs' claims, not a court finding.

Whatever happens with that case, the picture behind it is familiar to every owner I talk to. The insurance company has software on its side of the table. Medicare is testing AI-assisted prior authorization in six states through its WISeR model, which a House appropriations committee has voted to end. Your side of the table has a biller who's buried.

Why is getting paid getting harder for rehabs?

Reimbursement was already the top worry. In a 2026 industry survey, about a third of addiction treatment operators named reimbursement and funding uncertainty as their biggest challenge (Behavioral Health Business). One CEO in that piece, Doug Weiss of Porch Light Health, said his patients "are afraid that they're going to get a bill" and stop coming in.

January makes it harder. Under the new federal Medicaid rules, expansion patients have to prove eligibility every six months instead of every year, and the biggest coverage losses are expected to start in January 2027 (Penn LDI). People in addiction treatment can be exempt from work requirements, but they still have to get the paperwork in. A legal aid attorney in Philadelphia described patients who follow the rules and still lose coverage because a form showed up days before the deadline.

So AI won't fix your rates. Anybody who says it will is selling something. Where it pays off is the money you already earned and never collected.

What are the 4 revenue leaks in addiction treatment?

Think of it as a pipe. Care goes in one end and cash is supposed to come out the other. These are the four holes I'd plug first.

LeakWhat it looks likeThe fix
1. Admitting blindAn 11 PM admit, and three weeks later you learn the plan needed an approval first or pays a fraction out of networkAI benefits check before every admit, in seconds
2. Coverage that disappearsA Medicaid patient covered on day 1 and not on day 40 because a form wasn't filedAn agent that rechecks coverage every week and flags possible exemptions
3. Notes that don't prove the needThe chart doesn't show why the patient needs this level of care, so the review goes against youA behavioral health scribe, plus a gap check before the weekly review call
4. Money nobody fights forShort payments nobody notices and denials nobody appealsCompare every payment to what you were promised, then draft appeals for a person to sign

Every screen in the video is a sandbox I built: fake patients, fake insurance companies, fake claims. Nothing is connected to a live system. The demo numbers below come from that sandbox.

Leak 1: how do you check insurance benefits before an admit?

Somebody calls at 11 PM ready to come in tonight. Your team wants to say yes, and they should. But if nobody checks benefits, you can find out three weeks later that the plan needed an approval you never got, or that it's out of network and pays a fraction.

Checking benefits used to mean sitting on hold. In the demo, a plan and a member ID are all it takes. The insurance company sends back the usual gobbledygook, and the AI turns it into a clean read: the plan pays 80% after the deductible, $1,800 of a $3,000 deductible is still left, and IOP needs approval from the plan before day one. A person in admissions reviews it and calls for the approval.

The other two callers are the reason you do this every time. One is covered but out of network, so the family needs to hear about the difference before they arrive. The other's coverage ended September 30 because renewal paperwork was never filed. Nothing would get paid if care started that night. That one goes straight to a person to help with re-enrollment.

The basic check comes back in seconds. The details can still take a call to the insurance company. Sohar Health does AI eligibility checks built for behavioral health, and RVK AI, inside the Dazos CRM, answers admissions calls after hours and verifies insurance. Not sponsored, and I haven't verified these tools beyond their own descriptions; run each past the two rules below. The rule is simple: verify before you admit, every single time.

Leak 2: what happens when Medicaid coverage lapses mid-treatment?

Starting next year, a patient can be covered on day one and not covered on day 40 because the paperwork didn't get done. If nobody catches it, you may be treating them for free.

The fix is an agent that rechecks coverage on a schedule. Once a week is plenty. In the demo it's a Monday morning with 12 patients in the program. Two come back active with paperwork due. One comes back with coverage that ended January 26, and three visits since then are unpaid. All three get tagged as possibly eligible for the work-requirement exemption for people in addiction treatment so staff can help them file. The other nine need nothing.

That protects revenue. More important, it keeps patients from falling out of treatment over a form. Ask your eligibility tool or your biller if they can run checks on a schedule. If they can't, it's a simple agent to build.

Leak 3: why do rehab claims get denied for medical necessity?

Colorado's Medicaid program had an outside reviewer audit denials for residential and inpatient addiction treatment. Of the 421 sampled denials that turned on medical necessity (86% of the sample), the reviewer agreed with the denial 97% of the time (Colorado HCPF audit, January 2026). In plain English, the reviewer found the record didn't support that level of care. That audit covered residential care, not IOP, but the lesson carries.

The fix starts in the session. Eleos makes an AI scribe built for behavioral health. It listens with the patient's consent, drafts the note, handles group notes, and the clinician still reviews and signs it.

Then there's concurrent review, the weekly call where the insurance company decides whether to pay for another week. In the demo, one patient's week of notes goes in and a fix list comes out before the call: the treatment plan wasn't updated after the patient was caught drinking on August 15, no withdrawal checks were written down after that, and the August 19 group note is one line showing attendance and nothing else. A utilization reviewer marks it and goes to chase the fixes before the call.

It organizes what's already in the chart. It never fills in what's missing, and the clinician still decides the level of care. Anything that writes documentation that didn't happen, or codes a service higher than the chart supports, is a compliance problem. Stay away from it.

Leak 4: how do you catch insurance underpayments?

In my experience, most centers never catch an underpayment, because nobody compares what got paid to what was promised, claim by claim, every month. That's a perfect job for AI.

The demo runs 40 fake claims over two months against the rates the center was promised. Thirty were paid in full. Seven were paid short, for $7,127, and all seven came from the same payer. Three more were flat denied, worth about another $2,500. One denial says a weekly treatment wasn't medically necessary, so the AI drafts the appeal with the claim number, and the biller reads it, approves it and signs it before it goes out.

Cofactor AI does denial review and appeal drafting for hospitals. Ask your biller if they run anything like it.

Is AI for rehab billing worth it?

You can't win appeals you never file. In the class action over UnitedHealth's nH Predict algorithm, the patients claim about 9 out of 10 appealed denials were reversed (Healthcare Finance News). That's their claim, UnitedHealth disputes the case, and it's about Medicare Advantage post-acute care, not addiction treatment.

Few billing teams use these tools yet. Experian surveyed 250 people who run billing and claims at healthcare providers in mid-2025. 67% believe AI can improve the claims process, but only 14% use AI to reduce denials. Of those who do, 69% say it reduced denials or improved resubmissions (Experian Health, State of Claims 2025). In the video I said two out of three "know it well." The published figure is that 67% believe AI can help, so go with that one.

Big operators are already moving. Universal Health Services told investors in February 2026 that it's rolling out new revenue cycle technology in behavioral health, and its CFO said of AI, "It allows us to reduce headcount" (Becker's Hospital Review).

What rules apply before AI touches addiction treatment records?

Two rules, no exceptions.

  • Privacy. Any AI vendor that touches patient data signs a BAA, the HIPAA contract. Addiction records also fall under the federal rule called 42 CFR Part 2, which HHS has enforced since February 16, 2026 (Quarles). The vendor should sign a Part 2 qualified service organization agreement (QSOA) and handle Part 2 consent correctly. If they look confused when you say Part 2, walk away.
  • AI drafts, a human decides. No AI picks the level of care, and no appeal goes out without a person signing it.

None of this is legal or billing advice. Run your setup past your own compliance counsel.

What should a rehab owner do Monday?

Ask your biller four questions:

  • How many of our claims get denied the first time?
  • What percent of those denials do we appeal?
  • How many of those appeals do we win?
  • How many days does it take us to get paid?

If they can't answer all four, that's your first leak. Then turn on AI benefits checks for every admission, because that one pays back the fastest. Before January, set up coverage rechecks for your Medicaid patients. After that, the scribe and the appeals.

The insurance companies already have software on their side. You should too. Go ask those four questions this week, and the answers will tell you exactly where your money's leaking.

Frequently asked questions

Can AI raise a rehab's insurance reimbursement rates?

No. Payers, contracts and Congress set rates, and AI can't move them. Where AI pays off is collecting money you already earned: checking benefits before an admit, rechecking coverage every week, finding gaps in the chart before a review call, and comparing every payment to what you were promised.

Is it legal to use AI on addiction treatment records?

It can be, with two conditions. Any AI vendor that touches patient data has to sign a BAA, the HIPAA contract. Addiction records also fall under 42 CFR Part 2, which HHS has enforced since February 16, 2026, so the vendor should sign a Part 2 qualified service organization agreement (QSOA) and handle Part 2 consent correctly. If a vendor looks confused when you say Part 2, walk away. Check the specifics with your own compliance counsel.

Will AI write documentation so more claims get paid?

It shouldn't, and the tools in this post don't. A scribe drafts the note from the session with the patient's consent, and the clinician reviews and signs it. A review summary only organizes what is already in the chart and flags what's missing. It never fills anything in, never picks the level of care, and never codes a service higher than what was documented.

Which leak should a rehab fix first?

Benefits checks on every admission, because they pay back the fastest. Then set up weekly coverage rechecks for Medicaid patients before January 2027. After that, add the behavioral health scribe and the payment and appeal review.

Full video transcript

Ten rehabs in California are suing one insurance company. They say they billed over $15 million, but they only got paid about two and a half. That's 16 cents on the dollar. Insurance companies have been sued for using algorithms to deny claims. Medicare is testing AI on prior authorization in six states right now. So their side of the table has software. Your side of the table has a biller who is buried. We're going to talk about how to fix this.

If you run an IOP or rehab, you already know this one. Getting paid is one of the top worries in the industry right now. About a third of operators say it's their single biggest challenge. And it's about to get harder. Medicaid work requirements start January 1st, so Medicaid expansion patients have to re-qualify every six months. It used to be a year. People in addiction treatment can be exempt, but they still have to get the paperwork in. A legal aid lawyer in Philadelphia is already warning about that: people who qualify are still going to lose coverage over the form. One treatment CEO said it best: "Our patients are afraid they're going to get billed, so they stopped coming in."

AI is not going to raise your rates, and anybody who says that is definitely selling you something. Where it pays off is collecting money that you've already earned. And for most centers, that's a lot of money. I'm Dave. I help business owners pick and set up AI in their real businesses, and I'm going to show you four leaks to plug first and how to use AI for each one of them.

Think of this as your pipe. Care goes in one end, cash is supposed to come out the other. Every coin is money you already earned. Admitting blind, coverage disappears, notes don't prove the need, nobody fights back.

Leak number one. Somebody calls at 11 PM ready to come in tonight. Your team wants to say yes, and they should, but nobody checks the benefits. Three weeks later, you find out the plan needed an approval first and you never got one. Or you find out it was out of network and it's a fraction of the money collected. Checking benefits used to mean somebody sitting on hold with the insurance companies. AI handles that kind of stuff right now, and it does it really well.

So I put together a simple sandbox version, fake patients, fake data. It's late at night and a caller wants to come in. You've got a plan and a member ID, and that's all you need. We click on benefits and see what happens with this caller when we check benefits. We get some gobbledygook from the insurance company, but we get a clean output here that we're able to read. It pays 80% after the deductible. $1,800 of the $3,000 deductible is still left this year. IOP needs approval from the plan before the first day, so a person needs to check. We click review. It's reviewed by Dana in admissions at 11:06 PM, now calling for approval. Solid.

Let's take a look at one of these other callers. This is a little more of a problematic caller. The coverage is in, but it's out of network. The plan is covered, but it's out of network, so the family is going to be on the hook for the difference, and we need to make sure that's communicated. This is something that can happen from time to time.

Let's run this one. Coverage ended September 30th. The plan shows the renewal paperwork was never filed. Nothing would be paid for if care started tonight. Coverage can often be restored once the paperwork's filed, but this is going to need a person on it immediately. Let's get somebody to help with the re-enrollment. We can mark this as reviewed, clean and clear.

So that basic check comes back in seconds. The details still take a phone call to the insurance company. There are a lot of tools out there that can do the full version of this today. I put two of them on the screen right here. One of them plugs right into a CRM a lot of people already use. It answers your admission calls after hours, and it verifies your insurance. Simple rule: verify before you admit, every single time.

All right, leak two. This is the January problem. Starting next year, Medicaid patients can be covered on day one and then not covered on day 40 because the form didn't get filled out correctly. Nobody catches that, and you may be treating them for free. So the fix is an AI agent that re-checks coverage on a schedule. Once a week is plenty.

It's Monday morning next February, with 12 patients in the program this week. Let's see what happens when we click run. We get some flags. This one's active, but paperwork is due, so this gives us notice that we have to pay attention to it. Same thing here: active, but paperwork is due. And today we have one where the coverage has ended. Call today: three visits since January, and they're unpaid. You get a nice little note over here: two patients still need to re-qualify, one patient's coverage ended January 26th, all three may qualify for addiction exemptions, and nine patients are still active with nothing to do. Mark it reviewed, clean and clear.

So that protects your revenue. More important, it keeps patients from falling out of treatment over paperwork. Ask your eligibility tool or biller if they can run checks on a schedule. If they can't, it's a simple agent to build.

All right, leak three, your notes. Colorado ran an audit on this. They pulled Medicaid denials for residential treatment, and 86% came back with the same reason: the chart didn't prove the patient needed to be there. And the auditor agreed with the insurance company almost every single time. The paperwork just wasn't there.

The fix starts in the session. There is an AI scribe built for behavioral health. It listens with the patient's consent and it drafts notes. It even handles group notes, and your clinicians still review and sign them. Then there's the weekly review call. You know it as concurrent review. This is where the insurance company decides if they want to pay for another week.

Same sandbox, one patient, one week of notes, all fake. Let's run this and see what happens. We have a bunch of notes over here on the left done by Jordan. Let's run those notes through the system. These are the things we're going to fix before the call today. The treatment plan was last reviewed in August, and it wasn't updated after the patient was caught drinking on August 15th. No withdrawal checks were written down after August 15th. The August 19th group note is one line. It shows attendance, but nothing else. We mark it reviewed by Sam K. at 3:40, chasing the signature before the call, and it shows which notes to go fix. It organizes what's already in the chart. It never fills in what's missing. And the clinician still decides the level of care.

All right, leak number four, and back to that 16 cents. This next part is what the lawsuit says. The claims went to an outside company. Its job was to lower the payment, and the lawsuit says it kept a cut of whatever it saved. When the story ran, Cigna had not responded.

So think about your own center. In my experience, most centers never catch an underpayment, because nobody compares what got paid to what was promised, claim by claim, every month. This is a perfect job for AI. Forty claims, two months, and again, everything's fake. The one question is: did we get paid what we were promised? This is a big one, and this is where a ton of money leaks.

Let's run this. $7,127 short. Seven of the 37 paid claims, all from Cascade Ridge. We can look through these on the left. These are each of the short-paid claims, and this is the difference in the amount. Some of these were straight denied. So we had 30 claims paid in full, seven short payments and three flat-out denials. Those three denied claims were worth another 2,500 bucks. One of them is Jordan M.'s weekly treatment, denied as not medically necessary. So let's draft a quick appeal for this one. Just like that, we have an appeal drafted with the claim number. We read through it, approve it and sign it. Bam. Now the appeal can be sent to the insurance company. There are a lot of tools that already do this for hospitals, so ask your biller if they have something like that.

Is it worth it? There's a big lawsuit right now against UnitedHealth. The patients suing say that nine out of 10 people who appealed a denial won. That's their claim, and that case is about Medicare, which is a different kind of care. But the point holds: you can't win appeals you never file.

And almost nobody is using these tools yet. A survey asked 250 billing people about AI. Two out of three said they know it well, but one in seven actually used it. Most of the ones who did say their denials went down. Big operators are already getting it. One of the largest behavioral health companies in the country told investors it's rolling out a new billing technology, and its CFO said AI let them reduce headcount.

Before any of this touches your records, two rules. Rule one is privacy. There's a federal rule for addiction records called Part 2, and it's been enforceable since February. AI vendors that touch patient data have to sign a BAA. That's a HIPAA contract. And they have to handle Part 2 consent. If they look confused when you say Part 2 consent, walk away. Rule two: AI drafts, a human decides. No AI picks the level of care, and no appeal goes out without a person signing off on it.

So if you run a center, here's what I'd do on Monday. First, I'd ask your biller four questions. How many claims get denied the first time? What percentage of those denials do we appeal? How many of those appeals do we win? And how many days does it take to get paid? If they can't answer that, that tells you something. Then I'd turn AI benefits checks on for every admission. That one pays back the fastest. Before January, I'd set up coverage re-checks for Medicaid patients. After that, the scribe and the appeals.

The insurance companies already have software on their side, and you should too. AI is a force multiplier, but it's not magic. So use it to collect every dollar you've already earned. Comment PAID and I'll send you those four questions for your biller. And if you want me to map this out for your center, there's a free roadmap link below. Go ask those four questions this week. Those answers will tell you exactly where your money's leaking.
