Prior authorization means your insurer wants to approve a service before it agrees to pay for it. It does not always mean the care is not necessary. It means the insurer is adding an extra review step.
Your doctor recommends a treatment, test, or medicine.
The provider sends clinical notes and a request to the insurer.
The insurer reviews whether it meets its coverage rules.
The insurer approves, denies, or asks for more information.
Ask your doctor's office whether prior authorization is needed as soon as a test or treatment is ordered. If it is, ask who is submitting it, when it was sent, and whether anything else is needed from you.
Keep a record of calls, dates, and reference numbers. If a request is denied, ask for the denial reason and what the appeal process looks like. Many denials are administrative, incomplete, or appealable.
It also helps to ask whether the insurer requires "step therapy" or proof that another option was tried first. That detail explains many denials patients otherwise experience as random.
Approval is not a guarantee that you owe nothing. You can still have a deductible, copay, or coinsurance. Prior authorization only addresses whether the insurer considers the service eligible for coverage under its rules.
It also is not the same as medical necessity from your doctor's perspective. Prior authorization is an insurance gate, not the final clinical word on what care you need.
