Inside the Peer-to-Peer Window: Equipping Physicians for High-Stakes Clinical Reviews

Peer-to-peer review was conceived as a safeguard: a chance for the treating physician to explain the clinical reasoning behind a request to a qualified colleague before a final decision is made. In practice, it has become a routine and expanding part of the prior authorization process.

In the AMA’s 2024 prior authorization survey, almost two out of three physicians, 65 percent, reported at least sometimes having to participate in peer-to-peer reviews. Among those who participate, 56 percent said the number of these reviews had increased over the past five years.

Because the physician must speak directly with a health plan representative, these reviews interrupt patient appointments and consume clinical time that is already scarce. They are also among the highest-stakes moments in the authorization process, because the outcome of a single conversation can determine whether care proceeds.

The two participants in a peer-to-peer review rarely arrive equally prepared. The health plan reviewer typically has the payer’s coverage policy, the internal criteria being applied, and the record of what was submitted. The treating physician often has a few minutes between patients and a chart that was not organized with this conversation in mind.

The reviewer may not share the physician’s specialty. Only 16 percent of physicians who participate in peer-to-peer reviews told the AMA that the health plan’s “peer” often or always has the appropriate qualifications to assess the request.

That combination places a heavy burden on the physician. They must not only know their patient. They must translate the patient’s clinical picture into the language of a specific policy, anticipate objections from someone who may not be familiar with the standard of care in their field, and do it quickly.

A successful peer-to-peer conversation usually turns on a small number of elements. The physician needs to know which criteria the reviewer is applying, and which of those criteria the reviewer believes have not been met.

They need the patient’s most relevant clinical facts immediately at hand: diagnosis and staging, prior treatments and their outcomes, test results, contraindications to alternatives, and anything that distinguishes this patient from the typical case the policy was written for.

They need a clear response to the objections the reviewer is most likely to raise, ideally supported by guidelines or published evidence that the reviewer will recognize. And they need all of this in a format that can be scanned in seconds, before and during the call.

Assembling that information is research work. It is exactly the kind of work that a physician with a full clinic schedule has the least time to do.

When preparation falls short, the consequences extend beyond a single case. A denial upheld after a peer-to-peer review typically moves the patient into a longer appeal process, or forces a change in treatment plan, or ends with the patient abandoning care. In the AMA’s 2024 survey, 82 percent of physicians said prior authorization can at least sometimes lead to treatment abandonment.

The cumulative burden also falls on physicians themselves. Eighty-nine percent of physicians in the same survey said prior authorization somewhat or significantly increases physician burnout. Peer-to-peer reviews, which require direct physician time rather than staff time, are a significant part of that burden.

Physicians are also wary of how automation is changing the other side of the conversation. Sixty-one percent said they are concerned that artificial intelligence is increasing or will increase prior authorization denial rates. Preparation technology on the provider side should restore balance to that conversation, not add another layer of opacity.

Effective preparation can be distilled into a brief that answers four questions. What does the policy require? Which of the patient’s facts meet those requirements? What will the reviewer likely challenge? What evidence supports the response?

When that brief is prepared by someone other than the physician—from the payer policy, the patient record, and the review notice—the physician can spend their limited preparation time on judgment rather than research. They enter the call knowing the reviewer’s framework and their own strongest arguments.

Every point in the brief should be traceable to its source, whether a policy criterion, a note in the chart, a guideline, or a published study. That traceability is what allows the physician to speak with confidence and allows the reviewer to verify what they are hearing.

P2P Co-Pilot™ turns the payer policy, the patient record, and the review question into a focused call brief. It brings forward the relevant policy criteria, the key patient facts, the questions the reviewer is likely to ask with a clear response to each, and talking points tied to policy language, guidelines, and published sources.

The brief can be opened on a computer or a phone, so it is available in the minutes before the call and during the conversation itself.

Base9™ strengthens the clinical argument with current literature. It returns relevant trials, guidelines, and reviews with numbered citations, reading complete papers rather than only abstracts, so the evidence a physician cites is specific and verifiable.

The physician remains the expert in the conversation. Our role is to make sure they never walk into it with less information than the person on the other end of the line.
