Understanding Pre-authorization and Prior Authorization in Health Insurance

Navigating the world of health insurance can feel like decoding a secret language—especially when you hear terms like pre-authorization or prior authorization. Have you ever scheduled a medical procedure or filled a prescription only to learn that your insurance needed to “approve it first”? That’s pre-authorization at work.

What Is Pre-authorization in Health Insurance?

Pre-authorization, also known as prior authorization, is when your health insurance provider requires you to get advance approval before they agree to cover certain medical services, tests, or prescriptions.

It’s not a guarantee of payment, but rather a green light that says, “Yes, this treatment is medically necessary, and we’re likely to cover it.”

Think of it as insurance’s way of double-checking before footing the bill—especially for costly procedures or brand-name medications.

Why Do Insurance Companies Require It?

Pre-authorization helps insurance companies:

  • Ensure treatments are medically necessary
  • Control costs and overutilization
  • Encourage evidence-based care
  • Prevent fraud or duplicate services

While it can be frustrating, it’s a method used to balance cost and care quality—though the process isn’t always patient-friendly.

What Is the Difference Between Pre-authorization and Prior Authorization?

The answer is simple: nothing. These terms are interchangeable.

You might also see them called:

  • Insurance authorization
  • Medical necessity review
  • Utilization management

They all mean the same thing: your provider needs to get approval from your insurer before moving forward with a particular service or prescription.

When Is Pre-authorization Required?

Not every medical service needs pre-authorization. However, insurers usually require it for:

Common Examples

  • Elective surgeries (e.g., bariatric surgery, joint replacement)
  • Advanced imaging (e.g., MRI, CT scans)
  • Specialist treatments (e.g., physical therapy, dermatology, allergy shots)
  • Inpatient hospital stays
  • Brand-name or specialty medications
  • Durable medical equipment (e.g., CPAP machines, wheelchairs)

Tip: Always check your plan details or call the insurer (or use your BirdieNest portal) before scheduling a service that might need approval.

How Does the Pre-authorization Process Work?

Here’s a simplified step-by-step outline of how pre-authorization usually works:

1. Doctor Recommends a Service

Your healthcare provider determines a treatment or service is necessary.

2. Request Submitted to Insurance

Your provider submits a pre-authorization request to your insurance company. This includes medical records, diagnosis codes, and treatment rationale.

3. Insurance Reviews Request

The insurer evaluates the request based on:

  • Medical necessity
  • Plan benefits
  • Alternative treatments
  • Guidelines (like Medicare’s coverage rules)

4. Decision Made

  • Approved: Service can proceed, and insurance will likely cover it.
  • Denied: You’ll receive a notice with reasons. You can appeal.
  • Request for more info: Additional documentation may be needed.

5. Notification Sent

You and your provider receive written notice. It usually includes authorization number and time limits (e.g., approval valid for 30 days).

What Happens If You Skip Pre-authorization?

Skipping pre-authorization can lead to denied claims, leaving you responsible for 100% of the cost. That’s a nasty surprise, especially for something like an MRI or outpatient surgery.

How to Avoid This

  • Check your plan documents or call your insurer.
  • Use BirdieNest to compare plans with fewer pre-auth requirements.
  • Ask your provider’s office if they’ve submitted the request.
  • Track approvals in your online member portal or through BirdieNest.

How Long Does Pre-authorization Take?

On average, decisions take:

  • 24–72 hours for urgent services
  • 5–10 business days for non-urgent requests

However, it can vary by insurer, plan type, and provider responsiveness.

If you’re waiting too long, you or your provider can request an expedited review—especially for medically urgent cases.

What If Your Pre-authorization Request Is Denied?

Don’t panic. You have rights.

Here’s What to Do:

  1. Review the denial notice. It must explain why it was denied.
  2. Talk to your provider. There may be alternate treatments or appeal options.
  3. File an appeal. You can appeal with your insurer and request an external review.
  4. Get support. Birdie Insurance can connect you with licensed experts who can guide you through appeals and plan adjustments.
