KFF Report: Insurers on Federal Health Exchange Denied 19% of In-Network Claims
Disclosures, mandated by the Affordable Care Act, provide a limited snapshot of claim denials
Claim denials have created financial headaches for virtually all healthcare providers, including clinical laboratories and anatomic pathology groups. Reliable data about denials is hard to come by, but a recent analysis by KFF (formerly the Kaiser Family Foundation) revealed that insurers selling plans on HealthCare.gov denied 19% of claims for in-network services in 2023, the latest year for which data is available.
This is the highest rate since 2015, when KFF began tracking the data, according to the analysis. Claim denials for out-of-network services were even higher, amounting to 37%.
Patients and doctors “are saying that it’s become an even bigger hassle in recent years than it has been in the past,” said Kaye Pestaina, JD, co-author of the report, in a video report from CNBC. Pestaina is a KFF vice president and director of the organization’s program on patient and consumer protection.
The analysis, released Jan. 27, noted that the Affordable Care Act (ACA) requires insurers to provide data about health plans to state and federal regulators as well as the public. “However, federal implementation of this requirement has so far been limited to qualified health plans (QHP) offered on the federally facilitated Marketplace (HealthCare.gov) and does not include QHPs offered on state-based Marketplaces or group health plans.”
“One thing that we’ve seen [when] surveying consumers across different insurance types is that they simply don’t know that they have an appeal right,” said Kaye Pestaina, JD (above), VP and director of KFF’s program on patient and consumer protection, in a video report from CNBC. “If appeals were used more often, it might operate as a check on carriers. From what we can see now, so few are appealed, so it’s not operating as a check.” Clinical laboratories and anatomic pathology groups don’t often see data about the rate of claims denials by payers made public.

Scarce Information
The federal marketplace covers 32 states, which means that the data does not include the 18 other states or the District of Columbia, all of which have their own exchanges. Nor does it include employer-sponsored plans, Medicare Advantage plans, or Medicaid Managed Care plans.
“In the big picture, we’re still operating from a scarce amount of information about how carriers review claims,” Pestaina told the Minneapolis Star-Tribune.
Within this limited dataset, KFF found wide variation in denial rates among the parent companies of health plans. The companies with the highest rates were as follows:
- Blue Cross Blue Shield of Alabama (12 plans): 35%
- UnitedHealth Group (274 plans across 20 states): 33%
- Health Care Service Corporation (915 Blue Cross plans across four states): 29%
- Molina Healthcare (72 plans across nine states): 26%
- Elevance Health (154 plans across seven states): 23%
Rates also varied by state, from a high of 34% in Alabama to a low of 6% in South Dakota. However, the report noted that these averages sometimes obscured wide variations within each state. For example, in Florida, the statewide average was 16%, but denial rates for individual insurers ranged from 8% to 54%.
In most cases, in-network denial rates did not vary much based on plan levels. Rates were 15% for Platinum plans, compared with 18% for Silver and Gold plans, and 19% for Bronze plans. The rate for catastrophic plans was 27%.
The data offered only limited insights about the reasons for claim denials. The federal Centers for Medicare and Medicaid Services (CMS), which administers the rules, requires plans to report denial reasons, but it allows for an “Other” category that accounts for the largest number of denials:
- Other reason not listed – 34%
- Administrative reason – 18%
- Service excluded – 16%
- Enrollee benefit limit reached – 12%
- Lack of referral or prior authorization – 9%
- Not medically necessary (excluding behavioral health) – 5%
- Member not covered – 5%
- Not medically necessary (behavioral health only) – 1%
“We hear anecdotal stories about certain treatments that are denied, that arguably should not have been denied,” Pestaina told the Star-Tribune. “How often is that happening? It’s difficult to come to a conclusion with the kind of ‘reason’ information we have here.”
Health Insurers Pushback
In addition to claim denials, CMS requires insurers to report the number of appeals once a claim has been denied.
“As in KFF’s previous analysis of federal claims denial data, we find that consumers rarely appeal denied claims and when they do, insurers usually uphold their original decision,” the report states.
In total, insurers on the federal exchange denied 73 million in-network claims. Among these, less than 1% (376,527) were appealed internally to the insurers, which upheld 56% of the denials.
The report notes that, in some cases, consumers have a right to an external appeal in which a third party reviews the claim. However, in a separate survey, KFF found that only 40% of all consumers, and 34% of Marketplace enrollees, were aware of that right.
Health insurers pushed back on KFF’s analysis. In a statement reported by the Star-Tribune, UnitedHealth Group described the numbers as “grossly misleading” because the dataset represents only 2% of total claims.
“Across UnitedHealthcare, we ultimately pay 98% of all claims received that are for eligible members, when submitted in a timely manner with complete, non-duplicate information,” the company stated. “For the 2% of claims that are not approved, the majority are instances where the services did not meet the benefit criteria established by the plan sponsor, such as the employer, state or Centers for Medicare and Medicaid Services.”
