Why Many Denials Are Decided Before Submission: The Case for Front-End Policy Alignment

Prior authorization denials are common, and appeals of those denials are remarkably successful. A KFF analysis of Medicare Advantage data found that insurers received nearly 50 million prior authorization requests in 2023 and fully or partially denied 3.2 million of them, or 6.4 percent. Only 11.7 percent of those denials were appealed. Of the appeals that were filed, 81.7 percent resulted in the original decision being partially or fully overturned.

Those numbers describe a system in which a large share of denied care was ultimately judged appropriate, but only for the small fraction of patients whose providers had the time and resources to contest the decision. For everyone else, the denial stood.

Physicians explain why. In the AMA’s 2024 prior authorization survey, only 20 percent said they always appeal an adverse decision. Among those who do not, 67 percent said they did not believe the appeal would succeed based on past experience, 55 percent cited insufficient staff time or resources, and 53 percent said the patient’s care could not wait for the health plan to reverse its decision.

A successful appeal is a recovery, not a victory. By the time it arrives, treatment has been delayed, staff hours have been spent, and the patient has carried the uncertainty. The better question is how many of those denials could have been avoided before the request was sent.

The HHS Office of Inspector General examined a sample of prior authorization denials issued by Medicare Advantage organizations and found that 13 percent met Medicare coverage rules, meaning the services likely would have been approved under original Medicare. Among payment request denials, 18 percent met Medicare coverage and billing rules.

The causes the OIG identified are instructive. In some cases, plans applied clinical criteria that were not contained in Medicare coverage rules. In others, plans requested documentation that was not necessary, or stated that the medical record did not support the request when the records submitted were in fact sufficient. Human and system errors accounted for still more.

Not every one of these failures is within a provider’s control. But many denials share a common feature: the information the reviewer needed was not presented in a way that mapped clearly to the criteria the reviewer was applying. The supporting fact existed somewhere in the chart. It simply was not in the request, or it was buried in a document the reviewer was unlikely to read closely.

That is a preparation problem, and preparation problems can be solved upstream.

Avoidable denials tend to follow recognizable patterns. The request is submitted against the wrong policy because the patient’s plan was misidentified or the policy has changed. A required element—a prior therapy, a test result, a staging detail, a functional assessment—is documented in the chart but not included in the packet. The clinical rationale is generic rather than tied to the specific criteria the payer has published.

Each of these failures is predictable, and each is visible before submission if someone is looking for it. The difficulty is that the people preparing requests rarely have the time to look. The AMA’s 2024 survey found that practices complete an average of 39 prior authorizations per physician each week, and that physicians and their staff spend 13 hours each week on them.

Under that volume, staff naturally optimize for getting requests out the door. Checking each one line by line against a payer’s current coverage criteria becomes the step that is skipped, and the gap is discovered only when the denial arrives.

Denials and the delays they create are not purely administrative events. In the AMA’s 2024 survey, 93 percent of physicians reported that prior authorization delays access to necessary care, and 82 percent said it can at least sometimes lead patients to abandon a recommended course of treatment.

More than one in four physicians, 29 percent, reported that prior authorization had led to a serious adverse event for a patient in their care. Twenty-three percent reported that it had led to a patient’s hospitalization.

Every avoidable denial adds days or weeks to that timeline. Preventing it is therefore not only a revenue decision. It is a patient-access decision, and in some clinical areas it is a patient-safety decision.

Front-end policy alignment means treating every submission as an argument that must answer the payer’s criteria before the payer asks. It rests on three practices.

First, confirm the criteria. Identify the patient’s plan and the specific coverage policy that will govern the request, using the current version rather than a remembered one. Second, find the gaps. Compare the patient’s record against each criterion and identify what is missing or unclear while there is still time to obtain it. Third, write the rationale for this patient. Present the clinical facts in the order and language of the policy, so the reviewer can see at a glance that each requirement has been met.

None of this is new. Experienced authorization specialists do it instinctively for the cases they know best. The challenge is doing it consistently, for every request, across hundreds of payers and thousands of policies, without adding hours to each case.

Prisym™ gives teams a searchable library of more than 20,000 payer policies, so the applicable coverage criteria, documentation requirements, codes, and exclusions are visible beside the case rather than spread across dozens of payer websites.

Submission Co-Pilot™ carries those criteria into the request itself. It checks the case against the patient’s coverage criteria, shows what is missing before the request goes out, and prepares a patient-specific medical-necessity rationale for the physician to review and approve.

The goal is not to remove judgment from the process. It is to give the people who exercise that judgment a complete picture before the payer does. Appeals will always be necessary. They should be reserved for the decisions that genuinely require them, not spent recovering from gaps that could have been closed in advance.
