Kaiser Family Foundation Reports on Prior Authorization Denial Rates by Medicare Advantage Plans

Another report finds nearly half of all healthcare systems planning to opt out of Medicare Advantage plans because of issues caused by prior authorization requirements

Prior-authorization is common and neither healthcare providers (including clinical laboratories) nor Medicare Advantage (MA) health plans are happy with the basic process. Thus, labs—which often must get prior-authorization for molecular diagnostics and genetic tests—may learn from a recent KFF study of denial rates and successful appeals.

“While prior authorization has long been used to contain spending and prevent people from receiving unnecessary or low-value services, it also has been [the] subject of criticism that it may create barriers to receiving necessary care,” KFF, a health policy research organization, stated in a news release.

Nearly all MA plan enrollees have to get prior authorization for high cost services such as inpatient stays, skilled nursing care, and chemotherapy. However, “some lawmakers and others have raised concerns that prior authorization requirements and processes, including the use of artificial intelligence to review requests, impose barriers and delays to receiving necessary care,” KFF reported.

“Insurers argue the process helps to manage unnecessary utilization and lower healthcare costs. But providers say prior authorization is time-consuming and delays care for patients,” Healthcare Dive reported.

“There are a ton of barriers with prior authorizations and referrals. And there’s been a really big delay in care—then we spend a lot of hours and dollars to get paid what our contracts say,” said Katie Kucera (above),Vice President and CFO, Carson Tahoe Health, Carson City, Nev., in a Becker’s Hospital CFO Report which shared the health system’s plan to end participation in UnitedHealthcare commercial and Medicare Advantage plans effective May 2025. Clinical laboratories may want to review how test denials by Medicare Advantage plans, and the time cost of the appeals process, affect the services they provide to their provider clients.

Key Findings of KFF Study

To complete its study, KFF analyzed “data submitted by Medicare Advantage insurers to CMS to examine the number of prior authorization requests, denials, and appeals for 2019 through 2022, as well as differences across Medicare Advantage insurers in 2022,” according to a KFF issue brief.

Here are key findings:

  • Requests for prior authorization jumped 24.3% to 46 million in 2022 from 37 million in 2019.
  • More than 90%, or 42.7 million requests, were approved in full.
  • About 7.4%, or 3.4 million, prior authorization requests were fully or partially denied by insurers in 2022, up from 5.8% in 2021, 5.6% in 2020, and 5.7% in 2019.
  • About 9.9% of denials were appealed in 2022, up from 7.5% in 2019, but less than 10.2% in 2020 and 10.6% in 2021.
  • More than 80% of appeals resulted in partial or full overturning of denials in the years studied. Still, “negative effects on a person’s health may have resulted from delay,” KFF pointed out.

KFF also found that requests for prior authorization differed among insurers. For example:

  • Humana experienced the most requests for prior authorization.
  • CVS plans had the highest denial rate with 13%.
  • Anthem had the lowest with 4.2%.

Among all MA plans, the share of patients who appealed denied requests was small. The low rate of appeals may reflect Medicare Advantage plan members’ uncertainty that they can question insurers’ decisions, KFF noted.

Providers Opt Out of MA Market

Nearly 33 million people are members of Medicare Advantage plans, and seniors have about 40 different plans to choose from in 2025, according to the American Association for Medicare Supplement Insurance.

It’s a big market. Nevertheless, “between onerous authorization requirements and high denial rates, healthcare systems are frustrated with Medicare Advantage,”  according to a Healthcare Financial Management Association (HFMA) survey of 135 health system Chief Financial Officers.

According to the CFOs surveyed, 19% of healthcare systems stopped accepting one or more Medicare Advantage plans in 2023, and 61% are planning or considering ending participation in one or more plans within two years.

“Nearly half of health systems are considering dropping Medicare Advantage plans,” Becker’s reported.

Federal lawmakers acted, introducing three bills to help improve timeliness, transparency, and criteria used in prior authorization decision making. Starting in 2023, KFF reported, the federal Centers for Medicare and Medicaid Services (CMS) published final rules on the bills:

Rule One (effective June 5, 2023), “clarifies the criteria that may be used by Medicare Advantage plans in establishing prior authorization policies and the duration for which a prior authorization is valid. Specifically, the rule states that prior authorization may only be used to confirm a diagnosis and/or ensure that the requested service is medically necessary and that private insurers must follow the same criteria used by traditional Medicare. That is, Medicare Advantage prior authorization requirements cannot result in coverage that is more restrictive than traditional Medicare.”

Rule Two (effective April 8, 2024), is “intended to improve the use of electronic prior authorization processes, as well as the timeliness and transparency of decisions, and applies to Medicare Advantage and certain other insurers. Specifically, it shortens the standard time frame for insurers to respond to prior authorization requests from 14 to seven calendar days starting in January 2026 and standardizes the electronic exchange of information by specifying the prior authorization information that must be included in application programming interfaces starting in January 2027.”

Rule Three (effective June 3, 2024), requires “Medicare Advantage plans to evaluate the effect of prior authorization policies on people with certain social risk factors starting with plan year 2025.”

KFF’s report details how prior authorization affects patient care and how healthcare providers struggle to get paid for services rendered by Medicare Advantage plans amid the rise of value-based reimbursements.

Clinical laboratory leaders may want to analyze their test denials and appeals rates as well and, in partnership with finance colleagues, consider whether to continue contracts with Medicare Advantage health plans.

One Health System’s Secret to Medicare Advantage Success

Transition from Fee-for-Service to Value-Based Reimbursement for Hospitals, Physicians, and Clinical Laboratories Continues, Albeit Slowly, Reports Say 

Medical laboratories and anatomic pathologists may need to squeeze into narrow networks to be paid under value-based schemes, especially where Medicare Advantage is concerned

Pathologists have likely heard the arguments in favor of value-based payment versus fee-for-service (FFS) reimbursement models: FFS encourages providers to order medically unnecessary procedures and lab tests. FFS removes incentives for providers to order patient services more carefully. Fraudsters can generate huge volumes of FFS claims that take payers months/years to recognize and stop.

Studies that favor value-based payment schemes support these claims. But do hospitals and other healthcare providers also accept them? And how is value-based reimbursement really doing?

To find out, Chicago-based thought leadership and advisory company 4Sight Health culled data from various organizations’ reports that suggest value-based reimbursement shows signs of growth as well as signs of stagnation.

Value-Based Payment Has Its Ups and Downs

Healthcare journalist David Burda is News Editor and Columnist at 4Sight Health. In his article, “Is Value-Based Reimbursement Mostly Dead or Slightly Alive?” Burda commented on data from various industry reports that indicated value-based reimbursement shows “signs of life.” For example:

On the other hand, Burda reported that value-based reimbursement also has these declining indicators:

  • 39.3% of provider payments “flowed” through FFS plans in 2020 with no link to cost or quality. This was unchanged since 2019. (HCPLAN report)
  • 19.8% of FFS payments to providers in 2020 were linked to cost or quality, down from 22.5% in 2019. (HCPLAN report)
  • 88% of doctors reported accepting FFS payments in 2019, an increase from 87% in 2018. (AMA report)

Does Today’s Healthcare Industry Support Value-based Care?

A survey of 680 physicians conducted by the Deloitte Center for Health Solutions suggests the answer could be “not yet.” In “Equipping Physicians for Value-Based Care,” Deloitte reported:

  • “Physician compensation continues to emphasize volume more than value.
  • “Availability and use of data-driven tools to support physicians in practicing value-based care continue to lag.
  • “Existing care models do not support value-based care.”

Deloitte analysts wrote, “Physicians increasingly recognize their role in improving the affordability of care. We repeated a question we asked six years ago and saw a large increase in the proportion of physicians who say they have a prominent role in limiting the use of unnecessary treatments and tests: 76% in 2020 vs. 57% in 2014.

“Physicians also recognize that today’s care models are not geared toward value,” Deloitte continued. “They see many untapped opportunities for improving quality and efficiency. They estimate that even today, sizable portions of their work can be performed by nonphysicians (30%) in nontraditional settings (30%) and/or can be automated (18%), creating opportunities for multidisciplinary care teams and clinicians to work at the top of their license.”

Hospital CFOs Also See Opportunities for Value-based Care

In his 4sight Health article, Burda reported on data from a “Guidehouse Center for Health Insights’ analysis of a 2021 Healthcare Financial Management Association (HFMA) survey of more than 100 health systems CFOs that found that most said they are still interested in seeking value-based payment arrangements this year.”

According to the HFMA survey, among the arrangement CFOs indicated, 59% expressed interest in Medicare Advantage value-based payment contracts.

This could be problematic for clinical laboratories, according to Robert Michel, Editor-in-Chief of Dark Daily and our sister publication The Dark Report. According to Guidehouse, “Nearly 60% of health systems plan to advance into risk-based Medicare Advantage models in 2022.”

Medicare Advantage (MA) enrollments have escalated over 10 years: 26.4 million people of the 62.7 million eligible for Medicare chose MA in 2021, noted a Kaiser Family Foundation brief that also noted MA enrollment in 2021 was up by 2.4 million beneficiaries or 10% over 2020.

Graph of Medicare Advantage Enrollment
The graph above is taken from the Kaiser Family Foundation report, “Medicare Advantage in 2021: Enrollment Update and Key Trends.” According to the KFF, “In 2021, more than four in 10 (42%) Medicare beneficiaries—26.4 million people out of 62.7 million Medicare beneficiaries overall—are enrolled in Medicare Advantage plans; this share has steadily increased over time since the early 2000s.” Since MA employs narrow networks for its healthcare providers, it’s likely this trend will continue to affect clinical laboratories that may find it difficult to access these providers.

“The shift from Medicare Part B—where any lab can bill Medicare on behalf of patients for doctor visits and outpatient care, including lab tests—to Medicare Advantage is a serious financial threat for smaller and regional labs that do a lot of Medicare Part B testing. The Medicare Advantage plans often have networks that exclude all but a handful of clinical laboratories as contracted providers,” Michel cautioned. “Moving into the future, it’s incumbent on regional and smaller clinical laboratories to develop value-added services that solve health plans’ pain points and encourage insurers to include local labs in their networks.”

Medical laboratories and anatomic pathology groups need to be aware of this trend. Michel says value-based care programs call on clinical laboratories to collaborate with healthcare partners toward goals of closing care gaps.

“Physicians and hospitals in a value-based environment need a different level of service and professional consultation from the lab and pathology group because they are being incented to detect disease earlier and be active in managing patients with chronic conditions to keep them healthy and out of the hospital,” he added.

Value-based reimbursement may eventually replace fee-for-service contracts. The change, however, is slow and clinical laboratories should monitor for opportunities and potential pitfalls the new payment arrangements might bring.
