House Bill No. 1683 aims to amend existing laws regarding vision insurance, specifically addressing agreements between insurers or prepaid vision plans and vision care providers. The bill prohibits insurers from setting fees for services or materials unless they are covered under the contract. It also mandates that providers cannot charge more than their usual rates for noncovered services and ensures that reimbursements for covered services are made at customary rates. Additionally, the bill includes provisions that prevent insurers from using extrapolation in audits and from incentivizing patients to use services from entities they own, thereby promoting transparency and fairness in the vision care market.

Key changes in the bill include the insertion of language that clarifies the roles of insurers and prepaid vision plans in relation to noncovered services and materials, as well as the requirement for standard reimbursements for lenses of the same design and quality. The bill also emphasizes compliance for insurers regardless of their exemption status under other insurance laws. The act is set to take effect on July 1, 2025, and includes an emergency clause for immediate implementation upon passage and approval.
