How Long Does Prior Authorization Take for a Pediatric Patient?
The honest answer is: it depends. But that's not very helpful when your child is waiting for a medication that should have started last week, so let me give you real numbers based on what I've seen across 29 years of pediatric nursing and what current industry data shows.
Typical timelines:
For routine, non-urgent prior authorizations, most insurance companies say they'll respond within 5 to 15 business days. In my experience the realistic range is more like 3 to 10 business days when the submission is complete and clean. Some plans process common pediatric medication requests in under 48 hours. Others take the full 15 days every single time regardless of complexity.
For urgent or expedited requests, federal and state laws require faster timelines. Under most regulations, urgent requests must be reviewed within 72 hours, and many insurance companies process them within 24 hours. Urgent generally means a situation where waiting could seriously jeopardize your child's health, life, or ability to regain maximum function. Your child's doctor has to specifically request expedited review and provide clinical justification for the urgency.
Why timelines vary so much:
The biggest factor is whether the initial submission was complete. When the doctor's office submits everything the insurance company needs — diagnosis codes, clinical notes, treatment history, supporting documentation — the request can move through review quickly. When something is missing, the request gets “pended” or sent back, and the clock essentially restarts when the additional information is submitted. I've seen prior authorizations take three weeks not because they were complicated but because three rounds of back-and-forth happened over missing paperwork.
The second factor is the insurance company itself. Some carriers are notoriously slow. Some have efficient electronic submission systems and turn things around in hours. Some require fax submissions and physical mail. The carrier matters more than the type of request.
The third factor is timing. Prior authorization volume spikes at predictable times. The first quarter of every year is brutal because deductibles reset, plans change, and everyone's authorizations need to be redone. Back-to-school season in August and September is heavy because ADHD evaluations and therapy authorizations flood the system. End of year is heavy because families rush to use benefits before they expire. If your request hits during a peak period, expect the longer end of the range.
What you can do to speed it up:
Ask your child's doctor's office to submit the request as urgent if it medically qualifies. Don't ask for urgent review for something that isn't actually time-sensitive — that hurts your credibility and may delay the request further. But for things like new seizure medications, fast-progressing infections, post-surgical care, or therapy that needs to start before a developmental window closes, urgent designation is appropriate.
Call your insurance company directly and verify they received the submission. Get the reference number. Ask what the expected decision date is. Ask whether there is any missing information. The insurance company will not volunteer this information, but they will tell you if you ask the right questions.
If there's a delay that's hurting your child, escalate. Ask the insurance company for a supervisor. Ask your child's doctor to call for a peer-to-peer review with the insurance company's physician reviewer.
Contact your state insurance commissioner if you believe the carrier is violating its own timelines.
Typical timelines for common pediatric requests:
It helps to have realistic expectations for the specific kind of care your child needs. ADHD medication prior authorizations typically process in 2 to 5 business days when submitted cleanly, longer in August and September. Sleep study authorizations average a week to ten days. MRI authorizations average 5 to 7 business days. Therapy authorizations — physical, occupational, speech — tend to run on the longer end, sometimes two to three weeks, because they often require evaluation documentation the carrier reviews carefully. ABA therapy authorizations for autism can take 30 to 45 days because the documentation requirements are extensive. Biologics for severe asthma or other chronic conditions typically take a week to two weeks. Growth hormone authorizations almost always take the full 15 business days because the criteria are detailed and the cost is high.
These are averages, not promises. Your specific carrier, your specific plan, and the specific clinical situation all affect the actual timeline. But knowing the range helps you decide when something is genuinely delayed versus when it's just moving at typical pace.
What to do while you wait:
The waiting period is when most parents feel most powerless, but there are things you can do.
Document everything — the date the prescription was written, the date the request was submitted, the carrier reference number, every call you've made and who you spoke with. If the medication is something your child has been on before, ask the doctor's office about a one-time bridge prescription that doesn't require prior authorization to cover the gap. If the request is for therapy, ask whether evaluation sessions can be scheduled while authorization is pending. If the request is for imaging, ask whether the order can be modified to something less restrictive that might process faster.
The pediatric practices that work with Precision Pediatric Operations get faster turnaround on authorizations primarily because we submit complete, correctly-formatted requests on the first try and we actively work the queue rather than waiting for the insurance company to come back to us. Speed is mostly about removing the back-and-forth, not about pushing harder.
