A Patient-Friendly Guide to Understanding the Process (and Improving Your Chances of Approval)

If you’ve ever been told your prescription “needs a prior authorization,” you probably felt confused, or even frustrated. You’re not alone. Prior authorizations (PAs) are one of the most common delays patients experience when trying to get medications, especially newer or more expensive ones.

Let’s break down what a prior authorization actually is, how the process works, and what you can do to improve your chances of getting approved quickly.

What Is a Prior Authorization?

A prior authorization (PA) is a requirement from your insurance company that your doctor must get approval before a medication, test, or treatment will be covered.

In simple terms:

Your insurance is saying, “We need more information before we agree to pay for this.”

Why Do Insurance Companies Require Prior Authorizations?

Insurance companies use prior authorizations to:

• Ensure the medication is medically necessary
• Confirm that lower-cost alternatives have been tried first
• Prevent misuse or overuse of certain medications
• Control overall healthcare costs

Common medications that require PAs include:

• Brand-name drugs with cheaper generic options
• Specialty medications (e.g., for autoimmune diseases, cancer)
• Certain weight loss or diabetes medications
• High-cost inhalers or injectables

Step-by-Step: How the Prior Authorization Process Works

Understanding the process helps explain why it can take time.

1. Prescription Is Written

Your doctor prescribes a medication.

2. Pharmacy Processes the Prescription

The pharmacy runs it through your insurance and receives a rejection stating:
“Prior Authorization Required.”

3. Doctor Is Notified

The pharmacy notifies your doctor’s office, or the insurance company contacts them directly.

4. Doctor Submits Documentation

Your provider submits a PA request including:

• Diagnosis (why you need the medication)
• Medical history
• Previous medications tried (and why they didn’t work)
• Supporting clinical notes

5. Insurance Reviews the Request

The insurance company reviews the information against their criteria.

6. Decision Is Made

The request is either:

• ✅ Approved – Medication is covered
• ❌ Denied – Not approved (often due to missing info or not meeting criteria)

7. Appeals (If Needed)

If denied, your doctor can:

• Submit additional information
• File an appeal
• Request a peer-to-peer review with the insurance company

How Long Does It Take?

• Standard requests: 2–5 business days
• Urgent requests: 24–72 hours

However, delays are common if information is missing or incomplete.

Why Prior Authorizations Get Denied

Some of the most common reasons include:

• Not trying preferred (cheaper) medications first
• Missing documentation
• Diagnosis doesn’t meet insurance criteria
• Incorrect or incomplete forms
• Insurance plan exclusions

How Patients Can Improve Their Chances of Approval

This is where you have more control than you might think.

1. Know Your Insurance Formulary

Check which medications your insurance prefers.
If your doctor prescribes a non-preferred drug, a PA is more likely.

2. Share Your Full Medication History

Tell your doctor:

• What medications you’ve already tried
• Side effects you experienced
• What didn’t work

This helps them justify the request more effectively.

3. Ask If a Prior Authorization Is Needed Up Front

Before leaving your appointment, ask:

“Will this medication require a prior authorization?”

If yes, your doctor’s office may be able to start it immediately.

4. Follow Up (Don’t Assume It’s Being Handled)

Call:

• Your pharmacy
• Your doctor’s office
• Your insurance company

A quick follow-up can prevent days of delay.

5. Respond Quickly to Requests

If your insurance or doctor needs more information, respond ASAP. Delays here can stall the entire process.

6. Be Open to Alternatives

Sometimes a similar medication without a PA requirement can be used temporarily, or even permanently.

7. Understand the Appeals Process

If denied, don’t give up immediately. Many approvals happen after an appeal.

The Bottom Line

Prior authorizations can feel like a barrier, but they’re really a checkpoint in the insurance process.

The key to navigating them successfully is:

• Communication between you, your doctor, and your pharmacy
• Preparation with your medical history
• Persistence when delays or denials occur

Final Thought

As frustrating as prior authorizations can be, being proactive can significantly speed things up, and in many cases, make the difference between a denial and an approval.

If you ever feel stuck, your pharmacist can be one of your best resources to help guide you through the process.
