Manual prior authorization runs roughly $11 per transaction in staff time once hold time, documentation gathering and follow-up on pended requests are counted. Multiplied across a panel, it is frequently a larger cost than the denials it prevents.
Practices treat prior authorization as an annoyance rather than a cost, largely because it never appears as a line item. It is staff time, and industry measurement puts manual processing at roughly $11 per transaction.
Where the time goes
- Determining whether authorization is required for this code, this plan, this site of service.
- Assembling the clinical information the payer wants, in the form they want it.
- Submitting, and waiting — portal, fax, or phone with hold time.
- Following up on anything that pends, which is where most of the hidden time sits.
- Coordinating peer-to-peer review when it is requested.
The first and last of those are the expensive ones and the least visible in any workflow diagram.
Why the number matters
Because it sets the comparison. Outsourced prior authorization runs in a band that overlaps with what it costs to do manually in-house — so the decision is rarely a large saving in either direction. It is about capacity and consistency: whether the follow-up on pended requests actually happens when the person responsible is also running a front desk.
The number worth knowing
Authorizations per month, and average staff minutes each. Most practices have never counted, and the total is usually larger than expected — often more than a full-time role's worth spread invisibly across several people.
That figure is what makes the conversation concrete, whichever way it is resolved.
Measure it before you try to fix it
Count authorizations requested per month, the share that pend for clinical review, and the average number of contacts to resolve one. Three numbers, gathered over two weeks, and they turn an anecdotal complaint into a cost you can act on.
Practices that do this frequently discover the burden concentrates in a handful of payers and two or three service lines, which is a far more tractable problem than "prior authorization is out of control".
What to do with the number
It supports three decisions: whether to pursue electronic prior authorization with the payers that support it, whether to ask about gold carding at contract renewal, and whether a given low-margin service is worth offering at all once the authorization cost is loaded onto it.
That last one is uncomfortable and occasionally the correct answer.
The cost the patient pays
Authorization delay is not only administrative. It postpones care, and for a patient with a deteriorating condition that is a clinical cost that never appears in a billing report.
Practices that track time-to-authorization alongside cost-per-authorization frequently find the delay is the stronger argument — with the payer at renewal, and internally when deciding what to automate first.
Where automation actually pays back
The saving from electronic prior authorization concentrates in status checking rather than submission. A request that can be tracked without a phone call removes the majority of the staff time, even when the clinical review takes just as long.
That means the payers worth prioritizing for an interface are the ones you chase most, not necessarily the ones you submit to most.
Denied authorizations cost more than approved ones
An approval is one transaction. A denial is a peer-to-peer request, a scheduling exercise, a call, and frequently an appeal — several times the cost of the original request.
Costing authorizations by outcome rather than by volume gives a truer figure, and it usually shows the burden concentrated in a few services with poor approval rates.
Use it in contract conversations
A per-transaction cost multiplied by annual volume with a payer is a concrete number to raise at renewal, alongside your approval rate. It supports a gold carding request far better than a general complaint about administrative burden.
Common questions
- How much does a prior authorization cost a practice?
- Around $11 per transaction when handled manually, counting hold time, gathering clinical documentation and chasing pended requests — not the few minutes people assume.
- Where does prior authorization time actually go?
- Hold time and follow-up, not the submission itself. A request that pends for clinical review can take several contacts before anyone gives an answer.
- Does electronic prior authorization reduce the cost?
- Substantially, where a payer supports it end to end. The saving comes from removing hold time and status calls rather than from faster approval.
- Can I avoid prior authorization altogether?
- Sometimes, through gold carding — payers exempting providers with high approval rates from authorization for specific services. It is worth asking about at contract renewal.
- Is it cheaper to skip authorization and appeal the denial?
- Almost never. An unauthorized service commonly denies with no appeal route and no ability to bill the patient, so the whole charge is lost rather than delayed.
