Check Eligibility and Benefits: To identify if a service requires prior authorization for our members, check eligibility and benefits through Availity® 
or your preferred vendor.
Avoid post-service medical necessity reviews and delays in claim processing by obtaining prior authorization before rendering services. If prior authorization is required, services performed without prior authorization or that do not meet medical necessity criteria may be denied for payment and the rendering provider may not seek reimbursement from the member.
