When you manage a healthcare practice in Florida, you need a clear strategy for medicare and medicaid overpayment defense florida to avoid penalties and protect your revenue. Starting January 1, 2026, the new Florida law CS/CS/SB 1808 requires providers to refund patient overpayments for services billed to government health programs or private insurers within 30 days of identifying the overpayment. Failing to comply carries administrative fines, license restrictions and other sanctions. At Llaudy Law, we help you navigate regulatory compliance, appeals processes and audit defense with confidence.

Understand refund requirements

Florida’s CS/CS/SB 1808 mandates that licensed healthcare providers and facilities refund any patient overpayments within 30 days of determining the overpayment occurred. This refund requirement applies when charges are submitted to:

• Medicare or Medicaid
• Private insurers

Patient payments for self-pay services that are not billed to any insurer are excluded. Under Florida Statute 409.913 (2025), the Agency for Health Care Administration (AHCA) can also deny payment or require repayment for Medicaid goods or services not presented in compliance with statutory requirements.

Mitigate non-compliance risks

Non-compliance exposes your practice to severe consequences:

• AHCA fines up to $500 per violation per day, allowing penalties to accumulate quickly
• Disciplinary actions by the Florida Department of Health or licensing boards, including probation, suspension or revocation of your license
• Termination for cause sanctions if you relinquish your provider number or license after receiving notice of an audit or investigation
• Sanctions subject to hearing rights under Chapter 120, with the AHCA Secretary retaining discretion to adjust enforcement

To mitigate these risks, review your internal compliance policies, audit billing vendor agreements for accuracy and timeliness, and update your revenue cycle management procedures before the January 2026 effective date.

Navigate appeals processes

If you receive an overpayment demand or claim denial, you have a five-level appeals process available under federal law:

1. Redetermination by a different fiscal intermediary, carrier or Medicare Administrative Contractor filed in writing within 120 days of the initial determination
2. Reconsideration by a Qualified Independent Contractor (QIC) offering an independent review of medical necessity and coding issues
3. Administrative Law Judge (ALJ) hearing for disputes with at least $190 before January 1, 2026 or $200 on or after January 1, 2026, requested within 60 days of the QIC decision
4. Medicare Appeals Council review within 60 days of the ALJ decision
5. Judicial review in Federal District Court when the disputed amount is at least $1,900 before January 1, 2026 or $1,960 on or after January 1, 2026

Understanding these deadlines and thresholds is critical to preserving your right to challenge overpayment claims and pausing collection efforts.

• Maintain synchronized documentation of daily logs, invoices and clinical records
• Conduct periodic self-audits to identify potential overpayments and make voluntary disclosures
