How to Prepare for a Peer-to-Peer Review Call with Insurance
A practical guide written by a physician who has conducted thousands of P2P reviews as a medical director -- and fought for authorizations as a treating physician.
What Is a Peer-to-Peer Review?
A peer-to-peer (P2P) review is a phone call between the treating physician and the insurance company's medical director (or physician reviewer). It occurs after a prior authorization has been denied, and it's your opportunity to present clinical justification directly to another physician who can overturn the decision.
Most physicians dread these calls. They feel adversarial, they'rescheduled at inconvenient times, and the reviewer often seems to have already made up their mind. But here's the truth: the P2P call is the single most effective tool you have to reverse a denial. The problem isn't the system -- it's that most physicians walk in unprepared.
What the Medical Director Is Listening For
Having sat on the payer side of hundreds of P2P calls, I can tell you exactly what we're evaluating:
- Does the physician understand the specific denial reason? (Most don't -- they just say "my patient needs this.")
- Can they articulate medical necessity using criteria language (InterQual, MCG, or the payer's own clinical policy)?
- Have alternatives been tried and documented as failed or inappropriate?
- Is there a clear risk of harm or clinical deterioration if the service is denied?
- Is the physician organized, specific, and professional -- or vague and emotional?
The 5-Step P2P Preparation Framework
1. Know Your Denial Reason
Read the denial letter word for word. Understand exactly which criterion was not met. Your entire argument needs to address that specific criterion, not just why you generally think the patient needs the service.
2. Mirror Their Language
Medical directors review cases against clinical criteria. If you can reference those criteria by name and explain how your patient meets them, you immediately become more credible. Use phrases like "meets medical necessity criteria per..." and "consistent with InterQual admission criteria for..."
3. Lead with Alternatives Tried and Failed
One of the most common denial reasons is "conservative management not attempted." Be prepared to list every alternative that was tried, when it was tried, and why it failed or is inappropriate for this patient.
4. Quantify the Risk
State the specific clinical risk if the service is denied. "Risk of clinical deterioration" is vague. "30% risk of ICU admission within 48 hours based on CURB-65 score of 4" is specific and compelling.
5. Have a Strong Close
End with a clear, direct ask. Summarize in 2 sentences why the patient meets criteria and what you need approved. Don't trail off or wait for the reviewer to end the call.
Common Mistakes Physicians Make on P2P Calls
- Being emotional or adversarial instead of clinical and organized
- Not reading the actual denial reason before the call
- Using vague language ("my patient is really sick") instead of specific clinical data
- Not having the chart open during the call
- Forgetting to close with a clear ask
