Florida Terminates 220+ Medicaid Providers: What ABA Providers Need to Know for Future Audit
Florida’s Agency for Health Care Administration (AHCA) terminated more than 220 Medicaid providers in 2025 and 2026 after identifying billing patterns that defied basic math. Providers billing 96+ units (each unit is 15 minutes) for a single patient in a single day. That’s 24 hours of therapy in a 24-hour day. Services billed on consecutive days, including weekends and holidays, for months without a break.
Florida spent $6.57 billion on ABA services between 2023 and 2025, nearly four times more than any other state. After the terminations, projected ABA Medicaid spending fell from $3.86 billion to $2.88 billion. AHCA conducted more than 400 site visits and referred over 150 providers to the Attorney General for investigation.
These red flags matter beyond Florida. ABA practices billing Medicaid in any state should review daily units, service schedules, and billing records for patterns that could trigger an audit.
What ABA Billing Red Flags Triggered the Florida Medicaid Provider Terminations
The AHCA Medicaid Integrity Initiative began with data analytics rather than chart reviews. Algorithms flagged billing patterns that appeared clinically unsupported, prompting site visits, payment suspensions, and provider terminations. Here’s what the data revealed.
Billing more than 24 hours in a single day
Providers submitted claims totaling 96 or more 15-minute units for a single patient on one date of service. No clinical scenario produces 24 straight hours of ABA therapy. Claims like this are the fastest way to trigger a Medicaid fraud investigation.
Consecutive days of service with no breaks
Patients billed seven days a week, including holidays, for months on end. Even intensive ABA programs have off days. A pattern of unbroken daily billing looks fabricated in the claims data, whether it was intentional or not.
Rendering providers appearing in multiple locations simultaneously
RBTs showing up on claims at different addresses on the same date. If the same technician is billed as rendering services at two clinics 40 miles apart on the same Tuesday afternoon, someone filed a false claim.
Provider Identity and Enrollment Red Flags
Florida also introduced identity screening through SentiLink to help AHCA identify potentially stolen or synthetic identities and hidden ownership structures in Medicaid provider enrollment.
Duplicate Claim Submission
Submitting separate lines for services that should be grouped can trigger duplicate-billing flags in payer systems, even when the issue stems from a claim formatting error.
How does an ABA Medicaid Audit Work
An ABA Medicaid audit can start with a data flag, a complaint from a parent or former employee, a managed care plan referral, or a routine revalidation check.
During an audit, reviewers check whether staff are present and credentialed, session notes match billed units, supervision documentation meets state requirements, authorizations cover billed dates, and the rendering provider matches the person who delivered the session.
Consequences depend on the findings. Documentation gaps may lead to overpayment recoupment, while serious or repeated billing violations can result in payment suspension, provider termination, referrals for prosecution, or penalties under the False Claims Act and 18 U.S.C. § 1347.
What Counts as a Billing Error vs. Medicaid ABA billing Fraud
Not every audit finding is fraud. Billing errors can include a wrong modifier, an incorrect date, a duplicate claim, or a missing signature. These mistakes can lead to payment recoupment, but they are not automatically fraud.
Fraud involves intentional deception, such as:
Billing for services never provided or claiming more hours than were delivered.
Using false Medicaid IDs to submit claims.
Upcoding services, such as billing CPT 97155 when the service delivered does not support that code.
Falsifying supervision records to show oversight that never occurred.
Billing under a provider’s NPI when the provider was not involved as required.
An ABA billing red flag doesn’t automatically mean fraud. Florida’s actions are a reminder to review questionable claims, correct errors, and keep accurate treatment records to support billing.
How Can ABA Practices Prepare for a Medicaid Billing Audit
The federal government is pushing audits nationwide, not just in Florida. HHS launched AERO (Audit Enforcement Risk Oversight) in May 2026, an AI-led review of Single Audit records going back five or more years across all 50 states. CMS reported roughly $37 billion in Medicaid improper payments for FY2025, and 77% of those came from insufficient documentation, not fraud.
Here’s a five-step ABA provider audit preparation checklist your billing team can run this week.
Step 1: Check Your Treatment Records
Review Medicaid ABA claims from 2021 onward, where records are available. Make sure each claim has a signed session note matching the service date and billed units, required supervision records, and valid authorization for that date. List any missing records so your team can follow up.
Step 2: Review RBT Supervision Hours
Choose a recent week and compare RBT session records with BCBA supervision notes. Check whether supervision meets your state’s requirements. If anything is missing, review the reason and correct the process going forward.
Step 3: Check Prior Authorizations
List all active authorizations, including their start dates, end dates, and approved units. Flag those expiring within 30 days and compare billed units with the approved amount. Review this list every week to catch problems early.
Step 4: Verify the Rendering Provider
Check recent claims to make sure the rendering provider’s NPI matches the person who delivered the service, according to payer rules. Also, review your EHR settings. Some systems may automatically enter the supervising BCBA’s details when another provider delivered the session.
Step 5: Look for Unusual Billing Patterns
Run reports to find patients billed for more than 32 units (8 hours) in one day, providers billing at different locations on the same day, and patients with seven or more consecutive days of service. These patterns do not automatically mean fraud, but they deserve a closer look. Check the records, confirm the details, and correct any errors found.
FAQ
Can duplicate ABA claims trigger a Medicaid review?
Yes. Duplicate ABA claims can trigger a review. Auditors may compare claim records, session notes, and payment details to determine whether the duplicate was accidental or caused an overpayment.
What documentation problems can cause a Florida ABA Medicaid audit finding?
Unsigned notes, missing session details, or records that do not justify the services billed may lead to payment recovery. Florida Medicaid providers must keep documentation that verifies the care provided and supports their claims.
What records should Florida ABA providers keep for billing audits?
Keep session notes, assessments, treatment plans, authorizations, supervision logs, provider credentials, and claim records. Florida Medicaid generally requires records to be retained for at least five years.
