Prior authorization is a process where healthcare providers need to get approval from insurance companies before a service, medicine, or treatment is paid for. This step is meant to check if the service is needed and to stop the use of expensive or unnecessary procedures. In 2023, prior authorization was used much more, especially by Medicare Advantage (MA) plans.
Data given to the Centers for Medicare and Medicaid Services (CMS) shows that Medicare Advantage plans handled nearly 50 million prior authorization decisions in 2023. This number has gone up from 37 million in 2021 and 46 million in 2022. The number of people enrolled in Medicare Advantage rose too, from 22 million in 2019 to 31 million in 2023. On average, each Medicare Advantage member had almost two prior authorization decisions in 2023. Traditional Medicare uses prior authorization less often, with only about one decision per 100 people covered.
MA insurers require prior authorization for almost all enrolled members—about 99%. They mainly focus on high-cost services. The rising numbers show the expanding use of this system in health insurance but also point to challenges and problems with how prior authorization works.
One big effect of prior authorization is that it delays patient care. A 2024 survey by the American Medical Association (AMA), which included 1,000 doctors, found that 93% of them said prior authorization causes delays in getting needed treatments and services. These delays often break the flow of care and can hurt patient health.
The AMA reports that 24% of doctors saw serious bad events linked to delays caused by prior authorization in 2023. These events include hospital stays, worsened health problems, and in some cases, life-threatening issues that could have been avoided with faster care. Patients sometimes have to wait to start medicines or have treatments stopped, which can make their health worse.
Delays also lead to more use of healthcare resources. Almost 90% of doctors said prior authorization causes more use of health services, including extra doctor visits, emergency room visits, and hospital stays. For example, 42% of doctors noticed more emergency room visits because of delays linked to prior authorization, and 29% saw more hospital admissions tied to these delays.
These interruptions affect how well patients do and also disrupt how medical offices work. They also raise healthcare costs over time. The goal of controlling costs with prior authorization often fails, as delayed or denied care can lead to expensive hospital or emergency visits.
Another problem shown in 2023 data is that many patients stop treatment because of prior authorization. The AMA says 78% of patients have quit treatment when facing the hurdles of prior authorization rules. This quitting often comes from frustration with paperwork, long waits, or having to pay money out of pocket when insurance denies or delays coverage.
Out-of-pocket costs go up when denials mean patients must pay the full price for their medicines or services. In the AMA survey, 79% of doctors said prior authorization denials or delays sometimes made patients pay full cost for their prescribed medicines. This money pressure can stop patients from finishing their treatments, making long-term health worse and raising the chance of bad outcomes.
The money problems affect not only patients but also employers and the healthcare system. About 53% of doctors said prior authorization delays hurt the job performance of their patients who work. Health issues made worse by treatment delays can cause people to miss work and lose productivity.
Prior authorization causes a lot of extra work for healthcare providers. Doctors and staff handle about 39 prior authorization requests per doctor each week. This takes about 12 to 13 hours of administrative work every week. This hard work means less time is available for treating patients and adds to doctor burnout.
About 35% of medical offices have hired special staff just to handle prior authorization. But even with this help, 53% of doctors say prior authorization hurts how well they do their jobs. Many say they have to repeat requests, deal with unclear insurance rules, and take part in long peer-to-peer reviews. These reviews are often done by insurance people who may not have enough medical knowledge.
Denial rates increase the work. In 2023, Medicare Advantage plans denied about 6.4% of prior authorization requests (3.2 million). This is less than the 7.4% denial rate in 2022 but still a lot given the number of requests. Traditional Medicare has a much higher denial rate of 28.8% in 2023. Fewer appeals are made and fewer succeed compared to Medicare Advantage.
Appealing denials is hard. Only about 11.7% of denied Medicare Advantage requests were appealed in 2023. But of those appealed, 81.7% were partly or fully approved. This shows many initial denials may be wrong, but getting approval takes a lot of time and effort, which delays care more.
Prior authorization practices differ a lot among Medicare Advantage insurers. For example, Humana processed the most decisions per member (3.1) while denying only 3.5% of requests. Centene denied the highest percent of requests at 13.6% but handled fewer requests per member (2.4). Kaiser Permanente had fewer reviews (0.5 per member) and also fewer appeal wins.
This variation comes from differences in insurer rules, doctor networks, and the needs of the people they cover. Medical office managers need to use different plans to handle each insurer’s prior authorization rules well.
The Centers for Medicare and Medicaid Services (CMS) made rules between 2023 and 2024 to improve prior authorization in Medicare Advantage. These rules make the authorization criteria clearer, encourage electronic prior authorization (ePA), cut wait times, and require studies on how prior authorization affects people at social risk.
Starting in 2026, electronic prior authorization will be required to speed up communication between providers and insurers. This will reduce use of phone calls and faxes that slow approvals. CMS also suggested cutting reply times from 14 days on average to 7 days to make decisions faster.
These efforts aim to lower administrative work, make the process clearer, and reduce bad effects on patients. But many doctors say they still see heavy burdens and denials despite insurer promises.
Artificial intelligence (AI) and automation are being used more to improve prior authorization. Medicare Advantage insurers use AI to review requests quickly. AI can check clinical data, find missing information, and compare requests with coverage rules right away.
AI can help by cutting paperwork, shortening decision times, and letting staff focus on harder cases. For example, smart systems can approve routine requests automatically or remind doctors about needed papers before sending requests. This lowers delays.
However, AI can also cause new problems if its rules are too strict or miss important patient details. Doctors worry AI might increase denials or misunderstand patient needs because of limits in algorithms and data.
Combining AI with automation software helps medical managers and IT staff. These tools connect electronic health records, insurance websites, and communication systems to make the prior authorization process easier. They can track requests, update status in real time, and create appeals automatically if needed.
Some technology companies, like Simbo AI, offer AI systems that help medical offices handle many phone calls, lower staff costs, and answer patient questions better. Since prior authorization often needs lots of communication with insurers, these tools help reduce staff strain and make patients’ experiences better.
Health organizations, especially those with many Medicare Advantage patients, benefit from using AI and automation to manage growing demands in utilization management.
As prior authorization grows, medical office managers, owners, and IT leaders face big challenges. Balancing cost control, following rules, and giving timely patient care is hard with more work and complex insurer demands.
Managers need to hire enough staff for prior authorization tasks, invest in tech that automates and connects systems, and create plans that fit the different rules of insurers like Humana, UnitedHealthcare, Centene, and Kaiser Permanente.
IT leaders play a key role by putting in electronic prior authorization tools and AI systems that cut manual work and improve how clinical data is recorded. Meeting new CMS rules about electronic submissions and keeping data accurate will be important for success and good patient care.
Handling prior authorization well is important to lower administrative costs, reduce burnout, and stop care interruptions that can hurt health, raise patient costs, and cause bigger medical bills later on.
Prior authorization ensures that healthcare services are medically necessary by requiring approval before a service or benefit is covered. It aims to manage utilization and lower costs for insurers.
In 2023, Medicare Advantage insurers made nearly 50 million prior authorization determinations, reflecting a steady increase from previous years.
In 2023, insurers fully or partially denied 3.2 million prior authorization requests, which is approximately 6.4% of all requests.
Delays in obtaining prior authorization can impact timely access to necessary care, potentially resulting in worse health outcomes for patients.
The Biden Administration finalized rules to clarify criteria for prior authorization, streamline processes, and evaluate impacts on patients with social risk factors.
There is variation in the volume of prior authorization determinations, denial rates, and appeal outcomes across different Medicare Advantage insurers.
In 2023, 11.7% of denied requests were appealed, and 81.7% of those appeals were overturned, indicating potential issues with initial denials.
Medicare Advantage enrollees face more extensive prior authorization requirements, while traditional Medicare only uses it for specific services.
In traditional Medicare, the denial rate for prior authorization reviews reached 28.8% in 2023, indicating a higher likelihood of denial compared to Medicare Advantage.
AI is used by Medicare Advantage insurers to review prior authorization requests, but it may also contribute to administrative burdens and delays in care delivery.
