Prior Authorization

Medically Reviewed.Last updated on 02/11/2026.

Your healthcare provider recommended a treatment or medicine. But insurance requires a prior authorization. If you find yourself wondering why this extra bit of red tape exists, you’re not alone. But a denial on a prior authorization doesn’t mean you’re stuck. Working with your provider to appeal a denial can help you get the care you need.

What is a prior authorization?

A prior authorization (PA) is a type of permission a healthcare provider needs to get from your health insurance. If your insurance approves it, that means they’ll pay for the care your provider requested. PAs are also known as preauthorizations, precertifications or “prior auths.”

If your provider treats you without a PA, your insurance may refuse to pay for your care. That would leave you responsible for the costs. Or if you can’t pay, your healthcare provider or their organization would end up footing the bill. That’s why they wait for PAs.

Why do insurers require prior authorizations?

The main reason that insurance providers require PAs is to save money. PAs can do that in a few ways:

  • Brands vs. generics: Insurance plans use PAs to shift people they cover to less expensive, generic medicines when possible.
  • Location preference: Insurers may use PAs to encourage people to get care at certain hospitals or facilities. That’s usually a hospital that the insurer has a payment contract with.
  • Oversight: Insurance companies can use PAs to discourage unnecessary care. They often deny approval if providers don’t submit necessary information or meet certain requirements.

PAs can sometimes also protect you from potential harm. That can happen with:

  • Higher risk drugs and procedures: Insurers may require a PA for treatments or medicines that have a higher risk of complications. For example, many insurers require PAs on opioids.
  • Contraindications: Sometimes, a drug or treatment is contraindicated. That means it isn’t recommended for you for health reasons. Providers may need to get a PA to confirm that a treatment is necessary, even with the risks.

PAs have been around for years. Early on, they mainly applied to experimental drugs and treatments, which were often very expensive. But today, insurers use PAs for many treatments, including generic drugs and standard treatments.

What doesn’t need a prior authorization?

Providers don’t need a PA if you need emergency care. But they might need a PA for the care you need after emergency treatment. Some states have laws that exclude specific events, like giving birth or your newborn staying in a neonatal intensive care unit (NICU).

Some states have laws that require insurers to issue “gold cards” to providers with high PA approval rates. Having a gold card means your provider has proven themselves and doesn’t need to submit PAs.

Because the laws vary from state to state, you may want to look up what your state laws say about PAs. You can also learn more about PAs and how they affect you from your insurance company. Some ways to do that include:

  • Read documents and check websites. Many resources about PAs are available online. Your insurance provider’s website is a good place to start. Plan documents, either printed or in electronic form, can explain what you might need a PA for.
  • Ask healthcare staff. Many healthcare provider offices and organizations have staff who can also tell you more about PAs and help you understand them.
  • Talk to human resources at your work. If you have health insurance through your employer, a human resources (HR) staffer might be able to help you.
  • Contact state agencies. Many states have a department of insurance to oversee that industry. They may have information that can help you.

How long does prior authorization take?

Getting an answer on a prior authorization can take time. How long you wait depends on a few factors.

The first factor is the type of care you need. If the care you need is urgent, most states’ laws say the insurance company has to respond within one to three days. If the care isn’t urgent, insurance companies have several days to respond. Some states set that as short as two days or as long as 15 days.

Many states have laws that also set time limits on appeals. For urgent/expedited cases, insurers usually have between two and three days to respond to an appeal. For nonurgent cases, it can be up to 30 days.

Depending on the law in your state, the deadline for your insurance company’s response can vary. Some states’ laws specify that the countdown to the deadline starts when your insurer has all the paperwork needed to make a decision. It’s a good idea to check your state’s laws and/or ask your insurance plan for more information about what you can expect.

Some key details you might want to know about include whether your state law says:

  • If a PA is automatically approved if your insurance company doesn’t respond quickly enough
  • Whether insurance companies can retract a PA they previously approved
  • How long a PA lasts, and what kinds of care don’t need a renewal
  • If changing insurance plans cancels a PA (in some states, a PA remains active even after you change plans)

Who asks for a prior authorization?

Your healthcare provider or their staff, or pharmacy staff, are the ones who ask for a PA. Many electronic medical record systems can link with insurance company systems. Providers or medical/pharmacy staff check if a medicine or treatment needs a PA and then submit one, if necessary.

What happens if my insurance denies a prior authorization?

Insurance companies typically contact your healthcare provider first when denying a PA. Your provider can then tell you. Your insurer will also likely send you a letter by mail telling you about the denial.

If your insurance denies a PA, you aren’t out of options. Your provider can appeal the decision. They may ask you for more information or records related to your situation. Appealing and giving your insurance that information may be all it takes for your appeal to succeed. About 4 out of 5 appeals end up overturning an earlier PA denial.

If you have health insurance through your employer, you may also want to talk to someone in human resources (HR). They may be able to assist in appealing a denial. And you can also turn to your state’s department of insurance to file complaints or grievances, if necessary.

What are some things I should know about prior authorizations?

Depending on the law where you live, your insurance company might have to meet certain requirements when it comes to explaining PAs to you. That can include:

  • Giving you documents that are written in plain, easy-to-understand language
  • Notifying you in advance about changes to how they use PAs
  • Posting explanations and documents online for you to see, or giving you paper copies of those documents if you ask for them
  • Telling you if they deny your PA, and explaining why

Some examples of the documents you might ask for include:

  • An explanation of how their PA process works, including who makes decisions and how they make them
  • Lists of medicines or medical procedures that require a PA
  • A clear explanation of all the info or records they’d need to approve the PA for your care
  • An explanation of how to appeal if they don’t authorize your care, including when you should expect a decision
  • Evidence-based guidelines for approving/denying care

A note from Cleveland Clinic

Learning that you need prior authorization from your insurance can feel confusing. Insurance can be hard enough to understand under ideal circumstances. In stressful health-related situations, it might feel overwhelming.

But if you have questions, you don’t have to search for them alone. If you have questions about a PA, like appealing a denial or avoiding them altogether, ask your healthcare provider or one of their staff for guidance. They want to support you, and they’ll try to help you navigate this so you can get the care you need.
