Five Red Flags that Signal a Claim Needs Peer Review

Many treatment plans are straightforward. An injury occurs, a provider recommends care, and the claimant recovers. But some claims follow a different pattern, one where the medical record raises more questions than it answers. That is where medical peer review becomes a practical tool. Peer review refers to the clinical evaluation of a treatment plan by a qualified physician who assesses whether the care provided is medically necessary, consistent with the diagnosis, and appropriate for the stage of recovery. For claims professionals, knowing when to request a peer review is essential.

Five Red Flags that Signal a Claim Needs Peer Review

Red Flag 1: Treatment Continues With Little or No Documented Improvement

One of the clearest signals that a treatment plan deserves a second look is a long stretch of care with no measurable functional progress. Evidence-based clinical guidelines generally define care as medically necessary when it is expected to improve the patient’s condition or prevent deterioration. When neither is occurring, continued treatment may not meet that standard.

The Official Disability Guidelines (ODG), widely used in workers’ compensation claims management, set duration benchmarks for many common injuries. When treatment extends well past those benchmarks without documented functional gains, that gap warrants attention.

In a workers’ compensation context, extended treatment with flat outcomes can affect both the medical reserve and the direction of the claim. A peer review can help determine whether continued care is clinically supported or whether a different course, such as a functional capacity evaluation or a referral for case management, would be more appropriate.

Red Flag 2: The Treatment Plan Does Not Match the Diagnosis

A mismatch between what is being treated and how the injury occurred is one of the more straightforward flags to identify. If a claimant reported a minor soft tissue strain and the treatment plan escalates to nerve blocks, surgical consultations, or advanced imaging, the clinical rationale for that escalation should be clearly documented.

The American Medical Association (AMA) and specialty-specific clinical guidelines provide treatment benchmarks that align interventions with diagnosis and injury severity. When a treatment plan deviates significantly from those benchmarks without a documented clinical explanation, that deviation is worth examining.

An independent medical review can assess whether the proposed or ongoing treatment is causally related to the reported injury, which is a core question in both workers’ compensation and liability claims.

Red Flag 3: Sudden Escalation in Treatment Intensity, Referrals, or Procedures

A treatment plan that suddenly accelerates, particularly around claim milestones like independent medical examinations, deposition dates, or settlement discussions, can be a meaningful signal. Rapid escalation in the number of referrals, procedures, or diagnostic tests, without a corresponding change in clinical condition, is worth scrutinizing.

Research by the National Insurance Crime Bureau (NICB) has identified patterns in which treatment frequency and billing volume can increase during the life of a claim in ways that are inconsistent with the claimant’s documented clinical progress. While escalation alone does not confirm fraud or abuse, it does suggest that a utilization review or peer review may be appropriate.

A treating physician’s decision to add procedures or refer to multiple specialists is not inherently problematic. But when those additions appear disconnected from documented clinical need, a medical peer review can provide the objectivity needed to evaluate whether the escalation is supported.

Red Flag 4: Repeated Services with Unclear Medical Necessity

Repetitive billing for the same services, particularly passive modalities like electrical stimulation, ultrasound, or massage, over an extended period, is a pattern that appears consistently in claims involving overutilization. CMS guidance and evidence-based treatment guidelines generally support active, goal-directed rehabilitation rather than indefinite passive therapy.

According to the Coalition Against Insurance Fraud, insurance fraud costs the U.S. more than $308 billion annually, with healthcare fraud accounting for an estimated $105 billion of that total. Overutilization of services is one of the more common contributing patterns.

Not every repeated service reflects abuse. Chronic conditions and serious injuries can legitimately require extended care. The question a peer review helps answer is whether the frequency and type of services are clinically appropriate given the diagnosis, the stage of recovery, and the documented response to treatment.

A focused treatment plan review can identify whether a provider is following a structured, goal-directed plan or simply maintaining a billing cycle.

Red Flag 5: Gaps, Inconsistencies, or Missing Documentation in the Medical Record

A well-documented medical record is foundational to any claim evaluation. When records contain gaps in dates of service, contradictory clinical findings, vague or templated notes, or a lack of objective functional assessments, those deficiencies limit the ability to evaluate medical necessity.

The Centers for Medicare and Medicaid Services (CMS) notes that documentation must support the services billed and must be sufficient to justify the care provided. When a medical record does not meet that standard, claims professionals face the challenge of making decisions without adequate clinical information.

A peer review physician can assess the quality and completeness of the documentation, identify what is missing, and note whether the existing record supports the treatment that has been rendered or requested. This is particularly useful in claims involving surgical authorization requests or disputes over causation.

How Peer Review Supports Stronger Claim Decisions

Peer review is a clinical tool that helps claims teams answer specific questions such as:

• Is this treatment medically necessary?
• Does it align with the diagnosis and injury?
• Is the documentation sufficient to support it?

When those questions arise, having a qualified physician review the record brings a level of clinical credibility to the decision that claims professionals cannot provide on their own. That credibility matters, whether the outcome is authorization, a request for additional records, a recommendation for an alternative treatment path, or a referral for an independent medical examination.

Peer review is also a cost-effective step to consider before ordering an independent medical exam. An IME requires scheduling, travel, and a full in-person evaluation, which makes it a more resource-intensive option. A peer review, conducted as a records-based clinical review, can often resolve the core medical questions at a lower cost and in less time. When a peer review confirms that an IME is still needed, the claims team moves forward with a clearer focus and a stronger evidentiary foundation. In many cases, peer review answers the clinical question entirely, making an IME unnecessary.

Used appropriately, peer review strengthens documentation, supports defensible claim decisions, and helps ensure that treatment plans reflect genuine clinical need.
