The bill establishes new requirements for health care facility licensees and practitioners regarding the refund of overpayments made by patients. It creates a new section, 408.12, which mandates that licensees must refund any overpayment to the patient within 30 days of determining that an overpayment occurred. The term "tenders charges for reimbursement" is defined to include filing claims for reimbursement with government programs or private insurers. Additionally, the bill specifies that violations of this refund requirement will result in administrative fines under section 408.813.

Furthermore, the bill introduces section 456.0625, which imposes similar refund obligations on health care practitioners and their billing departments, requiring them to refund overpayments within the same timeframe. It also adds a new ground for disciplinary action under section 456.072 for practitioners who fail to comply with these refund requirements. The act is set to take effect on January 1, 2026.
