Why Peer Review Should Come Before an IME

In claims management, the order of operations matters more than most people realize. One of the simplest ways to improve both efficiency and outcomes is to rethink when independent medical exams (IMEs) are scheduled. Too often, the IME is treated as the default next step after questions arise in a claim—whether that is ongoing treatment that does not align with the injury, conflicting medical opinions, delays in recovery, or uncertainty around work status.

At that point, it can feel natural to move straight to an IME. However, while that approach is common, it is not always the most effective.

With approximately 2.6 million workplace injuries reported annually in the U.S. (U.S. Bureau of Labor Statistics), even small improvements in claims handling can have a meaningful impact on cost, speed, and overall outcomes. Starting with a full file peer review is one of those improvements.

Starting with a full file peer review is a simple shift that can drive meaningful improvements in both cost and outcomes.

What is a Full File Peer Review?

A full file peer review is a physician-led evaluation of all available medical records without an in-person exam. Instead, it provides a detailed, objective assessment based on existing documentation.

It focuses on three critical questions:

• Is the treatment medically necessary?
• Is it related to the claim?
• Is the care appropriate and consistent with the clinical picture?

In short, it addresses the core medical issues early, before introducing additional layers of complexity into the claim.

Benefits of Starting with a Peer Review Before an IME

1. Determines Whether an IME is Needed

IMEs are a standard tool in more complex or disputed lost-time claims, but not every case requires one.

A full file peer review helps distinguish between cases that truly require an IME and those that can be resolved without one. This alone can reduce unnecessary costs and keep claims moving forward without added friction.

2. Makes the IME More Targeted

When an independent medical exam is conducted without sufficient context, the result is often a broad, unfocused evaluation.

A peer review changes that. It identifies gaps, flags inconsistencies, and clarifies exactly what questions need to be addressed during the exam.

There is also strong evidence supporting the reliability of early medical review. Independent medical review outcomes uphold prior determinations approximately 91% of the time (California Workers’ Compensation Institute). This level of consistency reinforces the value of establishing a clear, evidence-based understanding of the file before escalating to an IME.

3. Brings Clarity Earlier in the Claim

Delays in claims handling often stem from uncertainty. The longer it takes to understand the medical direction of a claim, the longer everything else takes.

A peer review moves that clarity upstream. Instead of waiting for an independent medical exam to surface key issues, adjusters gain earlier insight into the full medical picture—allowing for faster, more informed decisions.

Despite its value, peer review remains underutilized. Only about 5–10% of claims receive a case-specific peer review, leaving significant room for improvement (WorkCompWire).

4. Reduces Rework and Follow-Ups

Without a peer review, IMEs can sometimes raise new questions rather than resolve existing ones. This often leads to follow-ups, supplemental reviews, and even repeat evaluations.

Starting with a full file peer review helps prevent that cycle. When an independent medical exam is needed, it is more focused and more likely to be done right the first time.

5. Strengthens the Overall Claim File

A well-documented claim is easier to defend.

A peer review demonstrates that decisions were based on a thorough, methodical evaluation of the medical evidence. It adds structure, supports consistency, and enables more confident decision-making throughout the lifecycle of the claim.

A Smarter, More Streamlined Approach

This is not about adding another step; it is about using the right step at the right time, and making the process easier to manage along the way.

Starting with a full file peer review helps:

• Avoid unnecessary IMEs
• Improve the quality of necessary IMEs
• Accelerate decision-making
• Reduce back-and-forth

But just as important as when these steps happen is how they are managed.

One of the biggest challenges in claims handling is coordination. When peer reviews and IMEs are handled by separate vendors, the process can become fragmented, introducing delays, misaligned communication, and unnecessary administrative friction.

Bringing both services under one roof eliminates that disconnect. The transition from peer review to IME becomes seamless, the clinical perspective stays consistent, and communication is clearer at every stage. Instead of restarting the process with a new provider, each step builds on the last, saving time and reducing the risk of rework.

The result is a more efficient, more cohesive claims process from start to finish.
