Summary
Missing prior authorisation is the single largest cause of avoidable denials, and a PA denial is usually not appealable.1 You delivered the service. The money is simply gone.
For a primary care practice at 15 to 25 PA denials a month and $180 to $320 each, pre-visit verification is reported to prevent $32,400 to $96,000 a year that no appeal can recover.1
Eligibility and authorisation requirements flagged at booking, while there are still days on the clock.
Book a demoWhy PA is the worst denial
Most denials can be fought. A coding error is correctable, a medical necessity dispute is arguable, an eligibility mismatch is often fixable after the fact.
A missing prior authorisation is none of those. The payer required approval before the service and you did not get it, and there is usually no route back. You did the work and you will not be paid for it, and reworking the claim costs $40 to $118 to establish that.44Industry analyses place the cost to rework a denied claim at $40 to $118 per appeal. Between 50 and 80 percent of denied claims are never resubmitted.
It also got worse in 2026. UnitedHealthcare, Aetna and Cigna each expanded their PA requirement lists for primary care, adding specialist referrals, advanced imaging orders and high-cost medication management visits that previously went through without pre-certification.22UnitedHealthcare, Aetna and Cigna each expanded prior authorisation requirement lists for primary care services in 2026, adding requirements to specialist referrals, advanced diagnostic imaging orders and high-cost medication management visits that previously flowed through without pre-certification. A static checklist from 2024 will now generate denials on services that used to be clean.
Where it has to be caught
Before the appointment, or not at all. Around 27 percent of denials originate in front-end causes including eligibility, prior authorisation and referral data, and 60 to 70 percent of all denials trace to the front end.33Approximately 27 percent of denials originate at the front end in eligibility, prior authorisation, referral and registration data. Broader estimates place 60 to 70 percent of all denials in front-end causes. Every one of those is preventable at the point of booking and irrecoverable afterwards.
Doing it properly needs a payer-specific PA matrix updated on each plan's policy revision cycle rather than a checklist somebody printed. Every scheduled appointment flagged against the current requirement list for that patient's plan, with the authorisation obtained before the date of service.
The workload is real and most practices do not carry it, so the money keeps leaving.
What WA\ Admin does
Eligibility runs at booking rather than at check-in, on the same record as the consultation. The authorisation requirement is flagged against the appointment while there are still days on the clock, not discovered on a remittance six weeks later.
Because it is one record, the requirement is checked against what the appointment is actually for. A booking with no clinical context cannot be checked against a plan's PA list in any meaningful way. A standalone front desk tool is structurally unable to do this.
The claim that was never at risk
A patient books on Tuesday for an MRI-adjacent workup. The plan added PA for advanced imaging in January. The requirement flags on Tuesday, the authorisation is obtained on Wednesday, the appointment happens on Friday and the claim pays.
No appeal was filed, because no claim was denied. Somewhere between $180 and $320 stayed in the practice, and the only thing that made the difference was checking a list before the patient arrived instead of after.
What we are not claiming
We do not submit prior authorisations for you and we are not an RCM company. Obtaining the authorisation is still work somebody in your practice does, and if you have a billing partner running a payer-specific PA matrix well, they are doing the harder half.
The figures here are third-party industry analysis, not our data, and PA burden varies enormously by specialty and payer mix.

Frequently asked questions
Can you appeal a prior authorization denial?
Usually not. No other denial type works this way. A coding error is correctable, a medical necessity dispute is arguable, an eligibility mismatch is often fixable after the fact. A missing prior authorisation means the payer required approval before the service was rendered and you did not obtain it, and no route back generally exists. You did the work and will not be paid. Reworking the claim costs $40 to $118 just to establish that. You catch it before the appointment or you do not catch it.
Did prior authorization requirements change in 2026?
Yes, and they expanded. UnitedHealthcare, Aetna and Cigna each added prior authorisation requirements for primary care services in 2026, covering specialist referrals, advanced diagnostic imaging orders and high-cost medication management visits that previously flowed through without pre-certification. A static checklist from 2024 will now generate denials on services that used to be clean. Doing this properly needs a payer-specific PA matrix updated on each plan policy revision cycle, which is a real workload and the reason most practices do not do it at all.
How do you prevent prior authorization denials?
At the point of scheduling. Every appointment flagged against the current PA requirement list for that patient plan, with the authorisation obtained before the date of service rather than after the claim is denied. Around 27 percent of denials originate at the front end in eligibility, prior authorisation, referral and registration data, and 60 to 70 percent of all denials trace to front-end causes. Every one of those is preventable at booking and irrecoverable afterwards, so the front end is the only place worth the effort.
Caught before the appointment, or not at all.
