Your Guide to Understanding Prior Authorization

What is prior authorization?

Prior authorization is a process that helps make sure health care is appropriate, effective and covered — before it happens.  

You’ll sometimes hear prior authorization called preauthorization, pre-certification or prior approval. 

Why do we do prior authorization?

  • We check that the service or drug asked for is covered by your plan for your health issue or condition.
  • We make sure it is considered appropriate and necessary based on proven clinical guidelines
  • We focus prior authorization reviews where they matter most, so you get the care you need.
  • We protect our member's safety and financial security by making sure the most high-cost and high-risk procedures are reviewed before care is delivered.

How do I know if I need prior authorization?

Most plans need prior authorization before you have certain services like surgeries, advanced imaging, specialty medications and some behavioral health treatments.*

Here's how to find out: 

  • Check your plan details – Requirements vary by plan, so review your benefits or member materials.
  • Search for your service or drug – Use our online tools to look up medical procedures, prescription drugs or behavioral health services that may require prior authorization.
  • Ask your doctor – In most cases, your doctor will know if prior authorization is needed and will submit the request for you.
  • Call customer service – If you’re unsure, call the number on your BCBSOK member ID card for help.

What to Expect: A Step-By-Step Guide

What does the prior authorization process look like? Here's a short guide to help you know what to expect:

  1. You and your doctor decide on the care you need. They'll normally tell you if your services or medicine need prior authorization.
  2. Your provider will normally start the prior authorization process by submitting documents to BCBSOK.
  3. Prior authorization is submitted to BCBSOK and reviewed.
  4. A decision is made and shared with you and your provider. If your request is denied, you or your doctor can file an appeal.

 

How can I check my prior authorization status?

To check the status of your prior authorization request, log in to your online member account. There, you'll see your prior authorization request history and the statuses.

Making Requests Simple

Most of the time, your doctor will take care of prior authorization for you. They’ll most likely submit a request and get approval before they offer your care. But it’s always a good idea to check, especially if your doctor's not in your plan network. If you use an out-of-network doctor, you may need to handle prior authorization. Start by calling the number on your member ID card.  

When you call, we'll need the following information:

  • Your name, subscriber ID number and date of birth
  • Your provider’s name, address and National Provider Identifier (NPI)
  • Information about your medical or behavioral health condition
  • Your provider's proposed treatment plan, including any diagnostic or procedure codes
  • When you'll get care and, if you're being admitted, an estimated length of stay
  • Where you’re being treated
