The Agency for Health Care Administration (AHCA) audits Florida Medicaid providers through its Office of Medicaid Program Integrity, and the exposure runs past the dollar figure on the first letter. Florida Statute § 409.913 authorizes AHCA to calculate an overpayment using statistical extrapolation across a provider's full claims population, not just the claims sampled. A provider that receives a final audit report has a narrow, statute-defined window to contest the number before it becomes the agency's final action, with interest accruing throughout.
AHCA's Medicaid Program Integrity Audit Process
AHCA's Office of Medicaid Program Integrity (MPI) audits Florida Medicaid providers for overpayments, billing errors, and suspected fraud under Fla. Stat. § 409.913. The statute requires AHCA to audit at least 5% of providers on a random basis each year, in addition to audits triggered by billing-pattern anomalies and peer-comparison outliers. MPI review can include a prepayment review period lasting up to a year without any specific suspicion of wrongdoing, and a completed audit must generally reach claims adjudication within 90 days, or 180 days when the agency has fraud evidence. Every audit proceeds in two stages: a preliminary audit report inviting a provider response, then a final audit report that starts the clock on appeal rights.
Overpayment Calculation Through Statistical Extrapolation
AHCA is authorized under § 409.913(20), Fla. Stat., to determine an overpayment using accepted auditing, accounting, analytical, statistical, or peer-review methods, including sampling with extension to the population the sample was drawn from. MPI reviews a limited set of claims, calculates an error rate, and applies that rate across the provider's entire Medicaid billing for the audit period, turning a review of a few dozen claims into a demand covering thousands. The final audit report required under § 409.913(21) must show the calculation, and a provider disputing the finding can rely only on records that were contemporaneous with the billed service and already furnished to AHCA during the audit; late-produced records do not count under § 409.913(22). The resulting recoupment accrues interest at 10% per year from AHCA's final determination under § 409.913(25).
The 21-Day Deadline to Request a Chapter 120 Hearing
A provider who receives AHCA's final audit report has the right to a hearing under §§ 120.569 and 120.57, Fla. Stat., Florida's Administrative Procedure Act. A petition for a formal hearing must comply with Rule 28-106.201, Fla. Admin. Code; an informal hearing petition follows Rule 28-106.301. Either way, AHCA must receive the petition within 21 days of the provider's receipt of the final audit report. Missing the deadline lets the finding stand as final agency action, foreclosing the audit appeal and leaving the overpayment, with interest running, uncontested. When a hearing is timely requested and disputed facts remain, the case moves to the Division of Administrative Hearings, where a hearing must occur within 90 days of the judge's assignment absent good cause, with evidence exchanged at least 14 days beforehand.
AHCA's overpayment finding becomes the agency's final action if a Florida Medicaid provider does not request a Chapter 120 hearing within 21 days of the final audit report.
Fraud Referral, Exclusion, and Multi-State Exposure
Not every AHCA overpayment finding stays a civil billing dispute. When the audit record shows a pattern rather than an isolated error, AHCA can refer the matter to Florida's Medicaid Fraud Control Unit, which evaluates the claims against the federal credible allegation of fraud standard and can expose the provider to False Claims Act liability separate from the civil overpayment. A Florida termination or exclusion that follows an audit carries collateral consequences, including reporting to the federal OIG exclusion list and other state Medicaid programs, detailed in Medicaid Exclusion and Termination: Collateral Consequences of an Audit. Compliance officers managing multi-state billing should also note the audit path differs outside Florida: State Medicaid OMIG Audits: Process and Defense covers the parallel process in states that route audits through an OMIG-style unit rather than AHCA's MPI structure.
Why Early Legal Counsel Is Critical
It is critical that Florida Medicaid providers promptly retain experienced healthcare defense counsel upon receiving an AHCA audit notice or final audit report. Early legal intervention can protect the provider's rights, ensure the response documents the extrapolation methodology AHCA used, avoid inadvertent admissions, and preserve the provider's hearing rights within the 21-day window. Delaying representation past that deadline can convert a contestable overpayment finding into final agency action.
