The Authorization Requirement Check That Saves the Work

Every prior authorization article assumes the authorization is needed. At an imaging center a meaningful share of them are not, and the authorization requirement check is the step that finds out before anyone has spent an afternoon on a submission nobody asked for.

The default at most imaging centers is to submit when in doubt. It feels safe. A study that goes out unauthorized and turns out to have needed authorization is a denial and a write-off, so staff submit broadly and absorb the cost of being wrong in the cheap direction.

Except the cheap direction is not cheap. Unnecessary submissions consume the same staff hours as necessary ones, they add days to the patient’s wait while everyone treats the study as pending, and they crowd the queue so the authorizations that genuinely matter get worked late. The practice pays for certainty it could have had in a lookup.

Requirement is a property of the plan, not the study

The reason this stays manual is that the answer lives in two places and neither is where the scheduler is looking.

Whether an imaging study needs authorization depends on the specific plan the patient carries, not on the modality alone. The same study can require authorization under one product and pass without it under another from the same carrier, and it can change with the plan year. A rule written as MRI always needs authorization is wrong often enough to be expensive in both directions.

Reading the patient’s coverage through GET /insurancepackages resolves which product is actually in effect, which is the input the requirement question needs. That is a different question from eligibility. Eligibility asks whether the coverage is active. The requirement check asks what that specific coverage demands for this specific study.

Most centers conflate the two because the same person does both in the same phone call, and the result is that requirement gets answered from memory or from a payer grid printed a year ago. Memory and stale grids are exactly the inputs that produce unnecessary submissions.

Check what already exists before assuming there is nothing

The second common waste is submitting for an authorization the practice already has.

Imaging orders frequently arrive from a referring office that has already done the work, and the authorization is sitting on the patient’s record. Reading GET /patients/{patientid}/referralauths before initiating anything catches that immediately. It also catches the case where an authorization exists but does not cover what was ordered, which is a different problem needing a different action.

This matters more for imaging than for most specialties because the order is usually external. The referring practice, the patient, and the imaging center all hold different pieces of the story, and none of them assumes another has already acted. So the work gets done twice, or not at all, roughly at random.

The sequence that removes most of the waste is short. Resolve the actual plan, check whether an authorization already exists and whether it covers the ordered study, then check whether the plan requires one. Only what survives all three goes into the submission queue. Everything else is scheduled immediately, which is the outcome the patient cares about.

The complication: the window, not the approval, drives the schedule

The reason this check has to happen at booking rather than in a nightly batch is that it changes when the patient can be seen.

At one multi-site practice, 6% to 8% of procedures were being scheduled outside the authorization window by human schedulers. The visit happened, the authorization did not cover the date, and the claim failed at the end of a process everyone believed had gone correctly. Getting the appointment to land inside the window at booking time is what makes the claim survive.

That produces two different scheduling behaviors from one check. A study that needs no authorization can be offered the next open slot. A study that does gets its earliest offer pushed out far enough for the authorization team to submit and receive a decision. Booking both the same way is how a center generates either dead claims or unnecessary delay, and usually both.

Rescheduling is the trap underneath. Moving an appointment silently breaks the link to the existing authorization, and a study whose authorization has not returned can be pushed later but never pulled earlier. Automation that reschedules on patient request without re-checking the window will cheerfully move a patient into a date their authorization does not cover. The rule has to be enforced on every change, not only at first booking.

Where the timelines are moving

The regulatory floor under this is changing in a way that makes the requirement check more valuable rather than less.

Under the CMS Interoperability and Prior Authorization Final Rule, impacted payers must send prior authorization decisions within 72 hours for expedited requests and seven calendar days for standard ones, and must give a specific reason when a request is denied. Operational provisions generally begin January 1, 2026.

Faster decisions do not remove the requirement check. They raise the return on it, because a center that knows within minutes which studies need submission can put the whole queue inside the new turnaround instead of discovering on day five that half of it never needed to be there.

The denial-reason requirement is the other half. A specific reason is actionable, which means the appeal or correction path becomes a defined workflow rather than a phone call to find out what happened. That only helps a center that is submitting the right things, because a queue full of unnecessary submissions produces reasons nobody needs to read.

Where the human belongs in this

The requirement check is a lookup, and lookups automate well. The judgment calls around it do not, and they should be routed rather than guessed.

When the plan cannot be resolved cleanly, because the patient has two active coverages, or the card on file does not match what the eligibility response returns, the answer is not a guess about which one governs. That goes to a person with both coverage records attached, because picking wrong produces a correctly-executed submission to the wrong payer.

When the ordered study is ambiguous, contrast or without, a protocol that could map to more than one code, the requirement answer may differ between the candidates. The automation does not choose the study. It flags that the requirement depends on which one is intended and routes it to staff, who resolve it with the referring office.

Everything else runs unattended and should. Resolve the plan, check for an existing authorization, check the requirement, and either release the appointment to normal scheduling or open a case in the authorization queue with the plan, the study, and the window already recorded. The staff who used to spend their morning finding out whether work was needed spend it doing the work that is.

Key Takeaways

Answer requirement before submitting. A meaningful share of imaging authorizations are submitted for studies the specific plan never required.
Resolve the actual plan product first. Requirement varies by product and plan year, so a rule written per modality is wrong often enough to be costly.
Check for an existing authorization before creating one. Imaging orders arrive from outside, and the referring office has often already done the work.
Separate eligibility from requirement. One asks whether coverage is active, the other asks what that coverage demands for this study.
Let the answer drive the offer. No authorization needed means the next open slot. Authorization needed means an offer far enough out for a decision to return.
Re-check the window on every reschedule. Moving an appointment breaks the authorization link, and a pending authorization can be pushed later but never pulled earlier.
Route unresolvable coverage and ambiguous study orders to staff with the records attached, rather than guessing and submitting cleanly to the wrong payer.

The authorization requirement check is the cheapest step in the whole prior authorization workflow and the one most imaging centers skip, because skipping it feels safer than being wrong. The cost shows up as staff hours spent on submissions nobody needed and patients waiting on a pending status that was never real. An AI team working scheduled studies inside athenaOne can resolve the plan, check what already exists, answer the requirement question in the time it takes to book, and route the genuinely ambiguous cases to the people who should decide them.
