Eligibility and Benefits

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.

Providers are strongly encouraged to use the  Availity® Essentials or their preferred vendor for eligibility and benefit verifications. With Availity’s Eligibility and Benefits Inquiry, users can access printable results that include up to date benefit information.

Verification of eligibility and/or benefit information is not a guarantee of payment. Benefits will be determined once a claim is received and will be based upon, among other things, the member’s eligibility, any claims received during the interim period and the terms of the member’s certificate of coverage applicable on the date services were rendered.
