Patient eligibility and benefits should be verified prior to every scheduled appointment. Eligibility and benefit quotes include membership verification, coverage status and other important information, such as applicable copayment, coinsurance and deductible amounts. It’s strongly recommended that providers ask to see the member’s ID card for current information and photo ID in order to guard against medical identity theft. When services may not be covered, members should be notified that they may be billed directly.
