Prior authorization is an approval of coverage from your insurance company, not your healthcare professional. It’s a restriction put in place to determine whether or not they will pay for certain medications.
Have you ever walked into the pharmacy and been told that your prescription requires prior authorization? But your healthcare professional prescribed something for you, and you brought in your prescription — shouldn’t that be enough? What exactly is an initial approval, and why can’t you just pick up your prescription?
GoodRx, a platform for medication savings, shares what you need to know about the prior authorization process.
Key takeaways:
- Insurance companies require prior authorizations for some medications. This includes those that may have less expensive alternatives.
- The prior authorization process can take anywhere from a few days to a couple of weeks. Once approved, the initial authorization lasts for a defined timeframe.
- You may be able to speed up a prior authorization by filing an urgent request. If you can’t wait for approval, you may be able to pay upfront at your pharmacy and submit a reimbursement claim after approval.
What is a prior authorization?
Prior authorization is an approval of coverage from your insurance company, not your healthcare professional. It’s a restriction put in place to determine whether or not they will pay for certain medications. Many people casually refer to it as a PA.
A prior authorization doesn’t affect cash payment for prescriptions. Plus, it’s only required on those prescriptions when billed through insurance. So if you’re uninsured or decide to pay in cash, you won’t need to worry about getting prior authorization.
What types of prescriptions require prior authorizations?
Insurance companies will most likely require prior authorizations for the following products:
- Brand-name drugs that have a generic available
- Drugs that are only intended for specific age groups or health conditions
- Drugs used only for cosmetic reasons
- Medicines that are neither preventative nor used to treat non-life-threatening conditions
- Drugs (including those prescribed at higher than standard doses) that may have adverse health effects, possibly dangerous interactions, and/or risks for abuse or misuse
- Drugs that aren’t covered by your insurance but deemed medically necessary by your healthcare professional
In many cases, prior authorizations are intended to ensure medication use is appropriate and cost-effective. If you think your prescription may require prior approval, contact your insurer directly to confirm.
What should you expect if your prescription needs a prior authorization?
If your medication requires a prior authorization, the pharmacy will notify the healthcare professional who wrote the prescription. Your prescriber will provide the necessary coverage information to your insurance company. Your insurer will then decide whether or not to cover your medicine.
Keep in mind: If you’re approved, a prior authorization only lasts for a set period. A prior approval can expire. You will likely have to reapply again for future fills once this happens.
How long does a prior authorization take for medication?
There’s no set timeframe for how long a prior authorization for medication typically takes.
Many prior authorization requests are processed in one to three business days, especially for standard medications with properly completed paperwork. Some insurance companies may take up to five to seven business days as part of their normal processing time. Urgent requests — like those for serious or life-threatening conditions — may be reviewed within a day. However, for complex or specialty medications, it can take a few weeks, especially if additional information is required or if an appeal is necessary following a denial.
The time it takes to process a prior authorization can vary for several reasons. Here are some of the most common ones:
- Insurance company requirements: Each insurer has its review process and timeline. Some may also ask for more documentation than others.
- Response and follow-up time: Delays can occur if your prescriber requires additional time to submit an initial request and/or follow up with the insurer.
- Paperwork issues: Missing or incomplete forms can lead to delays.
- Type of medication: High-cost or specialty medications often require extra scrutiny, which can slow things down.
- Submission method: Electronic prior authorization requests are now standard in the U.S. and are typically faster than fax or mail. However, some clinics and pharmacies still use these older communication methods.
What can you do if your prior authorization is denied?
Unfortunately, your insurer may deny your prior authorization request. If this happens, you may be left on the hook for the full out-of-pocket cost of your medication.
If you believe that your prior authorization was incorrectly denied, submit an appeal. Appeals are most successful when your prescriber deems your treatment medically necessary or when a clerical error led to your coverage denial. One of the best ways to build your appeal case is to get your healthcare professional’s input. Ask them about any backup documentation or medical notes that could help support the claim that your prescription is medically necessary.
If that doesn’t work, your prescriber may still be able to help you. Some tricks to help you save include:
- Getting a prescription for a higher-dose pill, which you can potentially cut in half to save on cost
- Filling a 90-day supply, which can be cheaper than a 30-day supply
- Getting free samples from your prescriber
Additionally, if you’re filling an expensive brand-only medication, look for any manufacturer copay cards, patient assistance programs, and other coupons that can help you save. And don’t forget to shop around.
Can you speed up the prior authorization process?
You may be able to speed up the process by speaking with your insurer directly. In some cases, you may be able to submit an urgent request for a faster decision.
If you need your medication urgently, some pharmacies may let you purchase your prescription with a credit card as you wait for prior authorization and reimburse you if your permission is approved within a week. If you have received initial approval for the same drug in the past, taking a risk will likely result in it being approved again.
Frequently asked questions
Why does my insurance need to approve a prescription?
Insurance companies use prior authorizations to make sure a medication is a safe, effective, and appropriate option for your condition. It’s a way to confirm that the treatment is medically necessary and helps avoid unnecessary costs. In some cases, your insurance may want you to try a lower-cost alternative before covering a brand-name, non-preferred, and/or specialty product. Prior authorizations can also help prevent misuse or overuse of certain medications. Overall, it’s one of the ways insurers try to balance quality care with cost.
Why is my prior authorization taking so long?
Prior authorizations can take time because your prescriber has to submit paperwork, and your insurance company needs time to review it. This process can take a few days — or even longer — especially if your insurer asks for more information or doesn’t classify the request as urgent. Delays can also happen when there’s a high volume of requests or when the process isn’t fully electronic. If you need the medication quickly, you or your prescriber can ask for an urgent request to help speed things up.
The bottom line
Your insurance company may require pre-authorization before covering your prescription. This is done in some cases to make sure that a medication is appropriate for your care. It also helps ensure it’s the most cost-effective option. There’s no set answer to how long a prior authorization typically takes for medication; it can range from a couple of days to a few weeks.
If you don’t get approval, you may be responsible for the cost of the medication, but you can appeal the decision. Your pharmacist may also know some tips to help make the medication more affordable for you, such as connecting you to manufacturer copay cards, patient assistance programs, or other discounts.
