Requirements Vary by Member

Prior authorization requirements are specific to each member based on their benefit plan. Check eligibility and benefits before rendering services. Submitting an electronic 270 transaction via the Availity® Provider Portal or your preferred vendor portal provides information about:

  • Coverage
  • Network status
  • Prior authorization requirements
  • Other important details

Obtaining benefit prior authorization is not a substitute for checking eligibility and benefits. We will not pay for services performed without the required benefit prior authorization. Providers may not seek reimbursement from our members. If you have any questions, contact the number on the member’s ID card.
