We will check your vision benefit eligibility and make every attempt to help you understand and make the most of your benefits. It is important to understand that things can change between the eligibility check and the actual payment of the claim. For example, changes in insurance, lapse of time, new benefit years, claims that arrive to the payer after eligibility was checked, and purchases made between checking eligibility. A quote of benefits is not a guarantee of benefits or payment. Charges not covered by your insurance company or benefit plan, as well as any co-payments, deductibles, and coinsurance amounts, are your responsibility.
