So today, instead of providing a guardrail against useless, expensive treatment, pre-authorization prevents patients from getting the vital care they need, researchers and doctors say.
“The prior authorization system should be completely done away with in physicians’ offices,” said Dr. Shikha Jain, a Chicago hematologist-oncologist. “It’s really devastating, these unnecessary delays.”
In December, the federal government proposed several changes that would force health plans, including Medicaid, Medicare Advantage, and federal Affordable Care Act marketplace plans, to speed up prior authorization decisions and provide more information about the reasons for denials. Starting in 2026, it would require plans to respond to a standard prior authorization request within seven days, typically, instead of the current 14, and within 72 hours for urgent requests. The proposed rule was scheduled to be open for public comment through March 13.
Although groups like AHIP, an industry trade group formerly called America’s Health Insurance Plans, and the American Medical Association, which represents more than 250,000 physicians in the United States, have expressed support for the proposed changes, some doctors feel they don’t go far enough.
“Seven days is still way too long,” said Dr. Julie Kanter, a hematologist in Birmingham, Alabama, whose sickle cell patients can’t delay care when they arrive at the hospital showing signs of stroke. “We need to move very quickly. We have to make decisions.”
Meanwhile, some states have passed their own laws governing the process. In Oregon, for example, health insurers must respond to nonemergency prior authorization requests within two business days. In Michigan, insurers must report annual prior authorization data, including the number of requests denied and appeals received. Other states have adopted or are considering similar legislation, while in many places insurers regularly take four to six weeks for non-urgent appeals.
Waiting for health insurers to authorize care comes with consequences for patients, various studies show. It has led to delays in cancer care in Pennsylvania, meant sick children in Colorado were more likely to be hospitalized, and blocked low-income patients across the country from getting treatment for opioid addiction.
In some cases, care has been denied and never obtained. In others, prior authorization proved a potent but indirect deterrent, as few patients have the fortitude, time, or resources to navigate what can be a labyrinthine process of denials and appeals. They simply gave up, because fighting denials often requires patients to spend hours on the phone and computer to submit multiple forms.
Erin Conlisk, a social science researcher for the University of California-Riverside, estimated she spent dozens of hours last summer trying to obtain prior authorization for a 6-mile round-trip ambulance ride to get her mother to a clinic in San Diego.
Her 81-year-old mother has rheumatoid arthritis and has had trouble sitting up, walking, or standing without help after she damaged a tendon in her pelvis last year.
Conlisk thought her mom’s case was clear-cut, especially since they had successfully scheduled an ambulance transport a few weeks earlier to the same clinic. But the ambulance didn’t show on the day Conlisk was told it would. No one notified them the ride hadn’t been pre-authorized.
The time it takes to juggle a prior authorization request can also perpetuate racial disparities and disproportionately affect those with lower-paying, hourly jobs, said Dr. Kathleen McManus, a physician-scientist at the University of Virginia.
“When people ask for an example of structural racism in medicine, this is one that I give them,” McManus said. “It’s baked into the system.”
Research that McManus and her colleagues published in 2020 found that federal Affordable Care Act marketplace insurance plans in the South were 16 times more likely to require prior authorization for HIV prevention drugs than those in the Northeast. The reason for these regional disparities is unknown. But she said that because more than half the nation’s Black population lives in the South, they’d be the patients more likely to face this barrier.
Many of the denied claims are reversed if a patient appeals, according to the federal government. New data specific to Medicare Advantage plans found 82% of appeals resulted in fully or partially overturning the initial prior authorization denial, according to KFF.
