What Is Prior Authorization? Why Your Insurance Company Sometimes Requires Approval Before Treatment

You've left your doctor's office with a treatment plan, only to receive a call a few days later saying:

"Your insurance requires prior authorization before we can move forward."

If you've never heard the term before, it can be confusing—and frustrating.

Many people assume their doctor has already decided they need the medication, procedure, or test, so why does the insurance company have to approve it too?

Let's take a closer look at what prior authorization is, why it exists, and what you can do if you encounter it.

What Is Prior Authorization?

Prior authorization (sometimes called preauthorization or pre-certification) is a process where your health insurance company reviews certain medications, medical services, or procedures before agreeing to cover them.

This doesn't necessarily mean the service won't be covered.

It simply means your insurance company wants additional information before making a coverage decision.

Why Do Insurance Companies Require Prior Authorization?

Insurance companies use prior authorization for several reasons, including:

• Confirming the treatment is medically necessary.

• Ensuring the requested service follows established medical guidelines.

• Determining whether a lower-cost treatment should be tried first.

• Reviewing services that tend to be high-cost or used less frequently.

While it can feel like an extra hurdle, the purpose is to help ensure treatments meet the plan's coverage requirements.

What Types of Services May Require Prior Authorization?

Every health plan is different, but prior authorization is commonly required for:

• Advanced imaging such as MRIs, CT scans, and PET scans

• Certain prescription medications

• Specialty medications

• Some surgeries and outpatient procedures

• Medical equipment

• Home health services

Just because something required prior authorization under one insurance plan doesn't mean it will under another.

Who Is Responsible for Obtaining Prior Authorization?

In most cases, your healthcare provider's office submits the request to your insurance company.

The provider sends medical records and documentation explaining why the requested treatment is appropriate.

The insurance company then reviews the information and makes a decision.

Patients are generally not expected to complete the medical documentation themselves, but it's still a good idea to follow up with your provider's office if you haven't heard anything after several days.

What Happens If Prior Authorization Is Denied?

A denial doesn't always mean the treatment can never be covered.

Sometimes the insurance company is asking for additional information.

Other times, your provider may choose to appeal the decision by submitting more medical documentation.

Depending on the circumstances, alternative treatment options may also be available.

If you receive a denial notice, don't ignore it. Read the explanation carefully and talk with your provider about the next steps.

Can Prior Authorization Delay Care?

Unfortunately, it can.

Some requests are approved quickly, while others take additional time depending on the complexity of the service being requested.

If your doctor recommends a service that may require prior authorization, ask:

• Has the request already been submitted?

• Is there anything you need from me?

• How long does approval typically take?

Staying informed can help avoid unnecessary surprises.

How Can You Be Prepared?

While you can't always avoid prior authorization, you can make the process smoother by:

• Keeping your insurance information up to date.

• Asking your provider whether prior authorization is required.

• Responding promptly if additional information is requested.

• Reading letters from your insurance company carefully.

• Following up if you haven't received an update.

A little communication can go a long way.
