Prior Authorizations by the Numbers: What the Data Reveals About Patient Care, Cost, and Control
Table of Contents
Prior authorizations have become a standard part of modern medical practice. Whether it’s prescribing a medication or ordering a diagnostic scan, chances are a provider has to stop and get approval before moving forward.
For most physicians, this isn’t an occasional interruption. It’s a daily task that slows down care and piles on administrative work.
In this blog, we’ll look at the real numbers behind prior authorizations—how often they happen, how often they’re denied, and what it really means for patients, providers, and the healthcare system as a whole.
Here’s what we’ll cover
- A simple definition of prior authorizations
- How many PAs a typical provider handles
- What types of treatments require them most
- Denial and appeal rates
- Who wins and who loses under the current system
What Are Prior Authorizations?
A prior authorization is an extra step a doctor has to take before moving forward with treatment. The insurance company needs to approve it first. Without that approval, they won’t cover the cost—even if the care is necessary.
This issue arises in various situations. Ordering an MRI. Prescribing a new medication and recommending physical therapy. The provider knows what the patient needs, but everything stops until the paperwork clears.
Prior authorizations for medication are one of the most frequent. Insurers often require them when:
- A brand-name drug is prescribed instead of a generic
- The medication is expensive or flagged as high-risk
- It’s being used outside typical guidelines
- The plan wants proof that other options were tried first
The process is rarely simple. It can take a few days or stretch into weeks. Some requests go through without issue. Others come back denied and need to be appealed. That means more forms, more phone calls, more delays.
Most doctors aren’t against oversight. But they’re the ones who have to explain the hold-up to patients. And the ones who lose time trying to fix it.
How Often Do Prior Authorizations Happen?
For many physicians, prior authorizations are not occasional tasks. They’re part of the daily routine. According to multiple surveys, the average provider deals with dozens of these every single week.
- Most doctors handle around 41 prior authorization requests per week
- Nearly 88 percent of providers say the volume is growing year after year
- Medical staff spend close to two business days each week handling these requests
These numbers reflect more than just paperwork. They represent lost time, delayed treatment, and growing strain on already busy practices.
The burden isn’t limited to one specialty. Prior authorizations show up across every kind of care, but some categories are more affected than others.
Common areas where prior authorizations are required
- Medications – especially injectables, specialty drugs, or brand-name prescriptions
- Imaging tests – MRIs, CT scans, PET scans
- Medical equipment – CPAP machines, mobility aids, diabetic supplies
- Outpatient treatments – physical therapy, behavioral health, rehab services
- Surgical procedures – particularly orthopedic or pain management related
Some providers build whole workflows around these requests. Others rely on third parties just to keep up. Either way, it’s clear the process has become a major part of how healthcare is delivered—and delayed.
Denials and Appeals: What the Numbers Show
Not every prior authorization request gets approved the first time. Denials are common—and many are preventable. What’s more surprising is how often denied requests are never appealed at all.
- Roughly 1 in 5 prior authorizations is denied
- Among those denied, only 11 to 15 percent are ever appealed
- Of the appeals that are submitted, up to 75 percent are overturned
These numbers say a lot. Most appeals succeed. But practices don’t always have the time or staff to fight every denial. Instead, treatment gets delayed or dropped entirely.
Why are so many prior authorizations denied?
- Missing or incomplete documentation
- Incorrect provider information
- Payer policies not matched to the request
- Expired or outdated patient details
- Failure to respond during the insurer’s review period
Some denials come from small clerical mistakes. Others are due to strict insurance rules that don’t leave room for clinical judgment. Either way, the result is the same—the patient waits, and the practice scrambles to resubmit.
For a system designed to reduce waste, the cost in time and labor is hard to ignore.
Do Prior Authorizations Improve Care?
That depends on who you ask. Insurers say they use prior authorizations to cut down on unnecessary treatment. On paper, that makes sense. But in a real-world setting, it doesn’t always play out that way.
Most providers will tell you the opposite. They see patients waiting days—or longer—for medications or tests that were already medically justified. By the time the approval comes through, the condition may have gotten worse or the patient may have given up.
Some common outcomes:
- Patients walk away from treatment
- Prescriptions never get filled
- Follow-up care is delayed
- Chronic conditions flare up from missed doses or appointments
Doctors aren’t against having guidelines. What they push back on is the volume, the red tape, and the delays that get built into care for no clinical reason. A review process might help in rare cases. But when it’s applied to nearly everything, it doesn’t improve care—it just slows it down.
Who Really Benefits from Prior Authorizations?
Insurers say prior authorizations are about safety and cost control. But when you look at how the system actually works, it’s easy to see who holds the advantage—and who doesn’t.
Insurance companies benefit the most.
They approve treatment on their timeline. They control what gets covered and when. For them, prior authorizations slow spending. That’s the point.
Providers do not benefit.
They lose time chasing approvals. They deal with frustrated patients. They carry the cost of delays, missed appointments, and unpaid claims.
Patients are caught in the middle.
They wait. They reschedule. Some skip care altogether. Not because they want to—but because the system makes it harder to move forward.
There’s no question some review is necessary. But when approval becomes the exception—not the rule—it stops protecting anyone but the payer. And that’s the part providers are being asked to work around every day.
Making Sense of the Numbers Behind Prior Authorizations
The volume of prior authorizations is high. The denial rates are steady. Appeals, when filed, are often successful. But most never get appealed. That tells us something important.
It shows that the system is heavy, slow, and often stacked against the people doing the work.
Here’s what stands out:
- Doctors handle 40+ prior auths every week
- 1 in 5 requests gets denied
- Most denials go unchallenged
- Appeals win more than 70% of the time
- But practices often don’t have the time to fight back
If the goal was to reduce unnecessary care, the success rate of appeals should be low. But it’s not. That means many denials probably shouldn’t happen in the first place.
These numbers suggest the process helps insurers control cost, but not much else. It doesn’t protect practices. It doesn’t improve patient care. It shifts the work onto providers and delays the very services patients are waiting for.
How Practices Can Respond
Most providers know prior authorizations aren’t going away. The real challenge is keeping them from taking over your day or delaying care for patients who are ready to move forward.
There are ways to stay ahead of it:
- Track how many authorizations you’re handling each week
- Create a step-by-step process for submitting and following up
- Train staff to avoid the most common mistakes that lead to denials
- Set time aside to appeal the ones worth fighting for
- Use a checklist to keep documents and timelines in order
Some practices assign the work to one team member. Others divide it across the front desk, billing, or clinical staff. But when the volume gets too high, that’s when mistakes and delays start to build up.
For practices looking to reduce the pressure, support through Revenue Cycle Management can help. Having the right team in place makes it easier to keep authorizations moving without pulling focus from patient care.
Final Thoughts and Key Takeaways
Prior authorizations aren’t just a paperwork issue. They affect the pace of care, the way practices operate, and whether patients get the treatment they need when they need it.
The numbers don’t lie. Doctors spend hours every week managing authorizations. Denials happen often, but most of them could be overturned—if there were time to push back. That time, for many practices, just isn’t there.
Here’s what matters going forward:
- Start tracking the full impact prior authorizations have on your practice
- Build a process early, and train your team to manage it smoothly
- Don’t ignore denials—many are reversible with the right follow-up
- Keep patient care at the center, even when the system makes it harder
- Get help where you can, especially when it frees up time for clinical work
Prior authorizations aren’t going away. But with the right approach, they don’t have to stall your practice either. The sooner you get ahead of the process, the less it will get in the way.
