In the American healthcare system, a patient's path to treatment often hits a wall built by insurance companies. What begins with a doctor's prescription or a recommended test can stall indefinitely behind a single bureaucratic hurdle: prior authorization. Originally designed as a modest check on unnecessary hospital admissions in the 1960s, this process has ballooned into a sprawling gatekeeping mechanism that now governs everything from prescription drugs to advanced imaging and surgeries.
The rise of managed care and preferred provider organizations in subsequent decades turned prior authorization into a nearly universal feature of American medicine. The theory was sound: doctors don't always follow evidence-based guidelines, and an estimated 25 percent of U.S. healthcare spending is considered waste, including overtesting and overtreatment. In fee-for-service models, where physicians earn more by doing more, that logic held weight.
But today, the practice has strayed far from its original purpose. Prior authorization is applied broadly and indiscriminately, even where there is no evidence of overuse. A federal report found that 13 percent of denials by Medicare Advantage plans were wrongful, raising serious questions about whether insurers are using the process to ration care, not manage it. The American Medical Association and patient surveys confirm that these delays and denials lead to worsening disease and even death. In a cruel irony, when patients deteriorate because of insurance barriers, they often end up needing more expensive care—costing both patients and insurers more in the long run.
While insurers offer appeal processes, including peer-to-peer reviews and formal appeals, many patients never pursue them. Limited health literacy, underestimation of success rates, and the sheer administrative burden mean that initial denials often function as de facto rationing by inconvenience. Marginalized patients are disproportionately affected. Unsurprisingly, seven in 10 patients describe prior authorization as a burden.
Some insurers are beginning to act. UnitedHealthcare recently announced plans to cut prior authorizations by 30 percent by the end of 2026. But broader reform is needed. As UnitedHealthcare's own step shows, voluntary measures may not go far enough.
The solution, many experts argue, is to shift the review process to independent clinicians—physicians and staff free from the financial conflicts that reward denials. These reviewers would operate under strict 48-hour deadlines and apply consistent, evidence-based guidelines developed by physicians, not insurers. Reviews would be targeted using claims data to identify costly, overused services, while routine and emergency care would be exempt. This tiered approach, pioneered in Massachusetts, transforms prior authorization from a blunt hammer into a precise scalpel.
Additional tools could strengthen this framework. Electronic health record systems should prompt doctors to follow evidence-based rules in real time. Hospitals should provide physicians with comparative reports on their adherence to those rules. Together, these measures would reduce administrative burden and physician burnout while ensuring patients get the care they need.
Insurance companies argue that prior authorization is essential for controlling costs. But for too many Americans, a health insurance card is a false promise. The system is broken—and it must be fixed now.
