Definition:Concurrent review
🏥 Concurrent review is a utilization management process used in health insurance and workers' compensation in which a clinical reviewer evaluates the medical necessity and appropriateness of care while treatment is actively underway. Rather than waiting until after services are rendered — as in retrospective review — concurrent review allows the insurer or its third-party administrator to make real-time decisions about continued authorization, discharge planning, and transitions between levels of care. This contemporaneous oversight is central to managing medical costs without compromising patient outcomes.
⚙️ Typically, a registered nurse or physician employed by the carrier or a specialized managed care organization monitors an admitted patient's progress against evidence-based clinical criteria — often benchmarks developed by organizations such as InterQual or Milliman. If the reviewer determines that continued inpatient stay is no longer medically necessary, the insurer may issue a denial of further inpatient authorization, prompting a step-down to outpatient or home-based care. The process involves close coordination with the treating physician and hospital case managers, and it must comply with state and federal regulations governing adverse benefit determinations and appeal rights. In workers' compensation, concurrent review also encompasses monitoring return-to-work readiness and ensuring that treatment stays within treatment guidelines specific to the injury.
📊 Effective concurrent review directly impacts an insurer's claims cost trajectory and, by extension, its combined ratio. Studies consistently show that timely intervention — redirecting patients to appropriate care settings before unnecessary costs accrue — yields better financial results than retrospective claim denials, which are harder to enforce and more likely to generate grievances and regulatory complaints. For health insurers and self-funded employer plans alike, investing in skilled clinical reviewers and integrated technology platforms for concurrent review is one of the most reliable levers for controlling loss ratios while maintaining quality of care and member satisfaction.
