What Prior Auth Actually Costs You

Ask a practice what prior auth costs, and you'll get an hours number.

Two FTEs. Part of a third. The time someone spends on hold, keying the same clinical detail into three different payer portals, chasing a pending that's been pending for nine days.

That's the visible cost. It's also the smallest one.

The real cost is the auth that never got worked.

The denial that came back on a Friday and sat over the weekend. The one that needed a peer-to-peer nobody scheduled. The appeal with a timely-filing window that closed while it sat in a queue.

And then there are the ones that look like wins. An authorization comes back approved. It gets logged, closed, counted as a success. And the medication still never reaches the patient, because something downstream broke that nobody was watching.

Approved is not the same as filled.

But only one of those shows up in your numbers.

Here's what makes it dangerous: the visible cost is easy to attack, and the hidden cost is easy to ignore.

So when a tool promises to cut prior auth time in half, it's answering the cheap question. It speeds up the clean submissions, the ones that were going to get approved anyway. The denials, the exceptions, the approvals that quietly die downstream still land in the same understaffed queue. Now they just land faster.

Faster submission and lower cost are not the same thing.

One is measured in hours saved. The other is measured in denials worked and approvals that actually reach the patient before the window closes.

Which number does your prior auth process actually report on?
