Prior authorization for medication typically takes about three days, though the actual wait ranges from 24 hours to over a week depending on your insurer, your state, and whether the request is classified as urgent. In a survey of more than 3,000 patients by the Arthritis Foundation, three days was the average wait, but 31% of respondents said they waited more than a week for an answer.
Standard vs. Urgent Timelines
Insurance companies distinguish between two types of prior authorization requests: standard (non-urgent) and expedited (urgent). Standard requests cover routine medication needs where a short delay won’t put your health at risk. Expedited requests apply when you need a medication quickly, such as for acute pain, a rapidly progressing condition, or a situation where waiting could cause serious harm.
For standard requests, most insurers take anywhere from two to seven business days. For urgent requests, the timeline shrinks to 24 to 72 hours. Your doctor’s office is the one who submits the request, and they can flag it as urgent if your medical situation warrants it. If your provider doesn’t mark a request as expedited, the insurer will process it on the standard timeline even if you personally feel the need is pressing.
What Your State Requires
Every state sets its own legal deadlines for how quickly insurers must respond to prior authorization requests. These vary widely. Some states give insurers as little as two business days for a standard medication request, while others allow up to 15 business days. Here’s a sample of the range:
- Fastest states for standard requests: Virginia and Oregon require a decision within 2 business days. Maine caps it at 72 hours or 2 business days, whichever is shorter. Arkansas also sets a 2-business-day limit.
- Middle range: New York, North Carolina, and Washington, D.C. require 3 business days. California, Indiana, Iowa, and West Virginia allow 5 business days. Vermont gives insurers 120 hours (5 days).
- Slowest states for standard requests: Ohio allows up to 10 calendar days. Colorado, Pennsylvania, and Rhode Island permit up to 15 days for non-urgent commercial plan requests.
For urgent requests, nearly every state requires a response within 24 to 72 hours. Kentucky, Virginia, and New Jersey mandate 24-hour turnarounds for urgent drug requests, while most other states set the limit at 48 or 72 hours.
One important detail: many of these clocks don’t start ticking until the insurer has received all necessary documentation. If your doctor’s office submits an incomplete request, the insurer can pause the timeline until the missing information arrives.
Federal Rules Taking Effect in 2026
A federal rule finalized by the Centers for Medicare and Medicaid Services (CMS) in 2024 will set new nationwide deadlines starting in 2026. Covered insurers will be required to respond within 72 hours for urgent requests and 7 calendar days for standard requests. This applies to Medicare Advantage plans, Medicaid managed care plans, and CHIP plans, though not all commercial insurers.
CMS has also proposed an additional rule with a potential compliance date of October 2027 that would tighten timelines further for prescription drugs specifically. Under this proposal, Medicaid programs would need to respond to drug prior authorizations within 24 hours, and qualified health plans on federal exchanges would face a 72-hour limit for standard drug requests and 24 hours for urgent ones.
Why Requests Get Delayed
The most common reason a prior authorization takes longer than expected is incomplete paperwork. Your doctor’s office needs to submit clinical documentation showing why the specific medication is necessary, often including what you’ve already tried and why alternatives didn’t work. If any piece of that information is missing, the insurer sends a request back for more details, and the clock resets.
Other delays happen when the procedure code or drug code submitted doesn’t match what the insurer has on file for the authorization. A prior authorization can also stall if your doctor’s office is handling a high volume of requests and doesn’t respond quickly to the insurer’s follow-up questions. Electronic submissions generally move faster than requests sent by fax, phone, or mail. Washington state, for example, gives insurers 3 calendar days to respond to electronic requests but 5 days for non-electronic ones.
What Happens If You’re Denied
A denial doesn’t mean the process is over. Your doctor can appeal the decision, and you have the right to appeal as well. For employer-sponsored health plans governed by federal law (ERISA), insurers must respond to your appeal within 60 days. Many states also offer an external review process where an independent third party evaluates whether the denial was appropriate. You typically have up to a year after receiving a final denial letter to request an external review.
Appeals add time, but they succeed more often than many patients realize. If your doctor provides additional clinical justification or peer-to-peer review (a phone call between your doctor and the insurer’s medical reviewer), the original denial can be reversed.
How to Keep the Process Moving
You can’t submit a prior authorization yourself, but you can do several things to prevent unnecessary delays. First, ask your doctor’s office to confirm the request has actually been submitted. It’s not uncommon for requests to sit in a queue at a busy practice for a day or two before anyone sends them. Second, call your insurance company directly to ask for the status. Get a reference number and the name of the person you spoke with. Third, ask whether your insurer has an online portal where you can track the request in real time.
If you’re waiting longer than your state’s legal deadline, say so when you call. Knowing the specific number of days your state allows gives you leverage. You can also ask your doctor’s office to submit the request as urgent if your medical situation has changed or worsened while you’ve been waiting. Finally, if your pharmacy told you a medication needs prior authorization, make sure your prescriber knows immediately. The sooner the request is filed, the sooner the clock starts.
