What Is Prior Authorization and Why Does Your Plan Require It?

Your doctor orders a test, then the office says they are waiting on approval from your insurance. We explain what prior authorization actually is, how the process works, and what we do when it gets in the way.

Few things in healthcare frustrate our clients more than being told their care is on hold while the insurance company reviews it. Prior authorization is the reason that happens. We help clients navigate authorizations every week, and once you understand how the system works, a confusing delay becomes a process you can actually manage. So let us break the whole thing down in plain language.

Most authorization requests move between your doctor’s office and your carrier, but knowing the process helps you keep it moving.

The Simple Definition

Prior authorization is approval from your health insurance carrier that a specific service, procedure, medication, or piece of equipment is medically necessary before you receive it. Carriers also call it preauthorization, precertification, or prior approval. All of those terms mean the same thing.

The key word is before. If a service requires prior authorization and you receive it without one, the carrier can deny the claim even if the service would otherwise have been covered. That can leave you responsible for the full bill.

Important distinction: prior authorization is not a guarantee of payment. It is a determination that the service meets the carrier’s criteria for medical necessity. The claim still gets processed under your plan’s normal rules for deductibles, coinsurance, and network status.

Why Carriers Require It

Carriers use prior authorization for a few stated reasons:

• Confirming medical necessity. The carrier checks that the requested care is appropriate for your diagnosis under accepted clinical guidelines.
• Steering toward proven options first. Some plans require trying a more established or lower cost treatment before approving a newer or more expensive one. With medications, carriers call this step therapy.
• Preventing duplication. The review can catch repeat imaging or overlapping treatments that add cost without adding value.
• Controlling costs. We will be honest with you about this one. Authorization requirements are also a cost management tool for the carrier.

Whatever the motive on a given request, the practical reality is the same: certain services need a green light first, and knowing which ones puts you in control.

What Typically Requires Prior Authorization

Every plan publishes its own list, and the list changes over time, so we always verify against your specific plan documents. That said, these categories commonly require approval:

• Advanced imaging such as MRI, CT, and PET scans
• Planned inpatient hospital admissions and many outpatient surgeries
• Specialty medications and certain brand name prescriptions
• Durable medical equipment such as wheelchairs, CPAP machines, and home oxygen
• Physical therapy, occupational therapy, and speech therapy beyond an initial number of visits
• Home health services and skilled nursing care
• Genetic testing and some specialized lab work

Routine office visits, standard lab work, and true emergencies generally do not require prior authorization. Emergency care is treated differently precisely because there is no time for a review, though carriers may still review the claim afterward.

The most expensive authorization is the one nobody requested. We always confirm whether a service needs approval before it gets scheduled, not after.

How the Process Works, Step by Step

1. Your doctor recommends a service. The provider’s office checks whether your plan requires authorization for it. Good offices do this automatically, but we tell every client to ask directly.
2. The office submits the request. The provider sends clinical documentation to your carrier explaining why the service is medically necessary. This usually happens electronically or by fax between the office and the carrier.
3. The carrier reviews it. A reviewer compares the request against the plan’s clinical criteria. Straightforward requests are often approved quickly. Complex ones go to a clinical reviewer for a closer look.
4. A decision comes back. The request is approved, denied, or returned with a request for more information. Approvals typically come with an authorization number and a validity window, often 30 to 90 days, during which the service must be performed.
5. You receive the care. The claim is then processed under your plan’s normal cost sharing rules.

How Long Does It Take?

Turnaround varies by carrier and by the type of request. Routine requests are commonly decided within several business days to a couple of weeks. Most carriers also have an expedited pathway when a delay could seriously jeopardize your health, and urgent requests are typically decided within about 72 hours. If your situation is urgent, make sure your doctor’s office labels the request that way, because the standard queue is much slower.

Whose Job Is It to Get the Authorization?

This depends heavily on network status, and it is one of the most important things we explain to new clients:

Situation	Who Handles the Authorization	Who Carries the Risk
In network provider	The provider’s office is generally responsible for requesting authorization as part of their contract with the carrier.	If an in network provider fails to get a required authorization, the financial consequence usually falls on the provider, not you. We still confirm it was obtained.
Out of network provider	Responsibility often shifts to you, the member. The out of network office has no contract with your carrier and may not handle it at all.	You. If the authorization was required and never requested, the denial and the bill can land on you.

The safest habit regardless of network status: before any major service, call the member services number on your insurance card, ask whether authorization is required, and if one was submitted, ask for the authorization number and write it down. When our clients face this, we make those calls with them or for them.

What to Do If a Prior Authorization Is Denied

A denial is not the end of the road. There are real options, and denials get overturned regularly.

• Find out why. The denial letter must state a reason. Common ones include missing clinical information, criteria not met, or a required first step treatment not yet tried.
• Fix the fixable. A large share of denials happen because documentation was incomplete. Your doctor’s office can resubmit with the missing records.
• Request a peer to peer review. Your doctor can speak directly with the carrier’s reviewing physician to make the clinical case. This conversation alone resolves many denials.
• File an internal appeal. Every plan has a formal appeal process with deadlines stated in the denial letter. Follow them exactly and keep copies of everything.
• Escalate to external review where available. If internal appeals are exhausted, many situations allow review by an independent third party whose decision the carrier must follow.

Practical tip we give every client: keep a simple log for any major service. Date of the request, the name of anyone you spoke with, the authorization or reference number, and the validity window. If a dispute ever arises, that log is worth its weight in gold.

Questions Worth Asking Before Any Major Service

• Does this service require prior authorization under my plan?
• Has the request been submitted, and what is the reference number?
• Was it approved, and what is the validity window?
• Does the approval cover the exact facility, provider, and procedure code being used?
• If anything changes about the procedure, does the authorization need to be updated?

That last question matters more than people expect. An authorization is specific. If the procedure changes, the facility changes, or the date slips past the validity window, the approval may need to be revised before you go in.

How We Handle This for Florida Clients

For Florida families, retirees under 65, and self employed professionals, prior authorization is one of those places where having someone in your corner makes a real difference. Plan rules differ, provider offices vary in how well they manage requests, and a single missed step can turn covered care into a surprise bill.

This is part of the White Glove service we provide every client. We help you confirm what your plan requires, we track down authorization numbers, and we stay on top of the process so you do not have to stress over it. And when a step can only be taken by you or your doctor, we guide you through it until it is fully resolved.
