What is prior authorization exactly?
Prior authorization is your health insurance company's way of saying "we need to approve this medical service before we'll help pay for it." Think of it as getting permission before making a big purchase with someone else's credit card.
Your doctor submits a request explaining why you need the treatment, test, or medication. The insurance company reviews it and decides whether it's "medically necessary" based on their guidelines. This process typically takes 1-7 business days.
Example: MRI without prior authorization
Let's say you need an MRI for back pain. The procedure costs $2,500.
With prior authorization (approved):
Without prior authorization:
That's a $2,250 difference for skipping one step.

If you're new to employer health insurance, prior authorization might sound scary, but it's actually designed to protect you from unnecessary costs and treatments.
Think of it like this: your insurance company wants to make sure you're getting the right treatment at the right time. They're not trying to deny you care - they're making sure the $3,000 MRI is really necessary before approving it.
Why this matters for entry-level salaries
When you're earning $35,000-$45,000, unexpected medical bills can be devastating. Prior authorization helps ensure you won't face surprise costs like:
Your role is simple
As the patient, you typically don't handle prior authorization directly. Your doctor's office does the paperwork. But you should:
1. Ask questions: "Do I need approval for this?"
2. Understand timing: Some approvals take a week
3. Know your benefits: Read your employee handbook's health section
4. Keep your insurance card handy: Doctors need your member ID
Common first-job scenarios
Scenario 1: Specialist referral
Your primary care doctor refers you to a dermatologist. Some plans require prior authorization for specialist visits.
Scenario 2: Prescription medication

After a sports injury, you need PT. Many plans pre-approve 6-12 sessions automatically.
