Florida cracks down on medical overbilling with new fines and a strict 30-day refund rule

New law sets a 30-day refund deadline

Florida patients who overpay for medical care now have a new tool on their side.

A law that took effect Jan. 1, 2026, requires healthcare providers to return overpayments within 30 days of figuring out the money is owed.

The clock starts when the provider determines a credit exists on the patient’s account.

Lawmakers passed the bill, CS/CS/SB 1808, during the 2025 session, and Gov. Ron DeSantis signed it into law as Chapter 2025-48.

Overpayments happen more often than you think

An overpayment is simple: you paid more than you actually owed. It happens all the time.

Maybe the office ran a duplicate charge, or a coding error inflated the bill. One of the most common situations?

You pay your copay upfront, then your insurance covers more than expected, leaving a credit sitting on your account.

Overpayments can also pop up when an insurer fully reimburses a provider after the patient already paid out of pocket.

Hospitals and individual doctors both fall under it

The law covers a wide range of providers. Any healthcare facility licensed by the Florida Agency for Health Care Administration (AHCA) must follow the rule, including hospitals and ambulatory surgical centers.

Individual practitioners licensed by the Florida Department of Health (DOH) are also on the hook. It doesn’t stop there.

Billing departments, management companies, and group practices that accept payments on a provider’s behalf all fall under the same requirement.

Who’s getting left out and why?

Here’s the catch. The law only kicks in when a provider submitted a claim to a government program like Medicare or Medicaid, or to a private insurer. If you paid entirely out of pocket, you’re not covered.

Cosmetic procedures and other services never billed to insurance don’t qualify either. That’s a big gap.

Uninsured and self-pay patients in Florida should know this law won’t help them get their money back any faster.

Fines can stack up to thousands per refund

AHCA-licensed facilities that miss the 30-day deadline face fines of up to $500 per violation. Under existing Florida law, each day a refund is late counts as a separate violation.

Do the math: a facility that sits on one refund for 60 extra days could rack up roughly $30,000 in fines.

The state classifies these as unclassified violations under Section 408.813 of the Florida Statutes, which gives regulators room to act quickly.

Doctors risk their licenses too

Individual practitioners face even more personal stakes.

For anyone licensed through the DOH, failing to refund on time now counts as grounds for disciplinary action, up to and including license suspension or revocation.

And here’s the part that makes it tough: practitioners bear the responsibility even when a third-party billing company or management group handles their payments.

If the billing department drops the ball, the doctor’s license is still on the line.

The law leaves one key term undefined

The 30-day clock starts when a provider “determines” an overpayment exists, but the law never defines what counts as a determination. Legal experts have flagged this as a gray area.

A provider could, in theory, delay formally acknowledging an overpayment in their system, which would push back the start of that 30-day window.

Until regulators or courts clarify the standard, this loophole could slow down the refunds the law was designed to speed up.

Patients cant sue but can file complaints

The law does not give patients the right to take providers to court over a late refund. There’s no private right of action in the statute.

But patients aren’t powerless. They can file complaints with AHCA for facility violations or with the DOH for individual practitioner violations. State regulators can then investigate and impose fines or discipline.

Documentation of your overpayment and any communication with the provider will make your complaint stronger.

Check your benefits statement after every visit

Want to know if you’re owed money? Start with your Explanation of Benefits (EOB), the statement your insurer sends after every visit.

Compare what you paid out of pocket with what your insurer says you actually owed. If your insurance covered more than expected, your provider may owe you a refund.

Keep every receipt, payment record, and EOB statement. Those records are your proof if you ever need to push for your money back.

Put your refund request in writing

If you think a provider owes you money, don’t just call. Contact the billing department in writing and reference Florida Statute 456.0625 or 408.12 by name.

State exactly how much you believe you’re owed and when the overpayment happened. Ask for a written response within 30 days.

Keep copies of everything you send. That paper trail matters if the situation ends up in front of state regulators.

File with the right state agency

If your provider won’t cooperate, you can take it to the state.

For hospitals and other AHCA-licensed facilities, file a complaint with the Florida Agency for Health Care Administration. For individual doctors and DOH-licensed practitioners, go to the Florida Department of Health.

Either agency can launch an investigation that leads to fines or disciplinary action. Bring your EOB statements, payment records, and copies of any letters you sent to the provider.

The law closes one gap but leaves others open

Before this law, Florida had no specific deadline for providers to return patient overpayments. Insurance companies already had protections against overpaying providers, but patients had nothing similar.

SB 1808 changes that for insured patients. But self-pay patients still have no deadline working in their favor, and the undefined “determination” trigger gives providers room to delay.

The law is a step forward, but it doesn’t cover everyone.
