The fundamental promise of any healthcare system is to provide care for those who are sick. However, a landmark study from KFF reveals that for millions of Americans living with multiple or complex health conditions, that promise is increasingly ringing hollow. A comprehensive new survey of more than 25,000 adults paints a grim portrait of a landscape where financial instability, bureaucratic hurdles, and systemic exclusion are forcing the most vulnerable patients to choose between their health and their livelihoods.
The State of the Crisis: Main Facts
The KFF survey, conducted in May 2026, illuminates a deep-seated affordability crisis. Among adults aged 18-64 who manage multiple or complex conditions—such as cancer, cardiovascular disease, diabetes, lung disease, or mental health disorders—the struggle to survive is not just medical; it is financial.
Approximately one-third of this demographic reported being unable to pay or struggling significantly to pay their medical bills over the past year. The data reveals that the severity of the financial burden correlates directly with the complexity of the patient’s condition. For instance, 36% of those managing three or more conditions, and an equal percentage of those living with mental health disorders, report insurmountable medical debt. This financial pressure forces a grim "trade-off" economy: one in four adults with multiple conditions has been forced to slash essential household expenses—such as food, rent, or utilities—simply to keep up with the ballooning costs of their medical care.
A Chronology of Declining Access
The descent into poor health for these populations often follows a predictable, tragic trajectory:
- The Financial Barrier: Patients are hit with high out-of-pocket costs, often exceeding their monthly disposable income.
- Delayed Care: Faced with these costs, patients begin to ration their healthcare. Nearly half of those with three or more conditions admitted to skipping or delaying necessary medical appointments or treatments in the past year.
- Medication Rationing: When the cost of life-saving medication becomes prohibitive, patients skip doses or fail to fill prescriptions entirely. One in five patients with complex needs admits to this practice.
- Clinical Deterioration: The final, inevitable stage is the worsening of the patient’s condition. Because they have foregone preventative or maintenance care, their health declines, leading to more acute, expensive, and complex medical crises later.
Data Analysis: The Weight of Complexity
The KFF survey utilized a massive sample size to gain granular insight into specific patient populations. The data confirms that health status is a direct predictor of economic vulnerability.
The Impact on Specific Conditions
The research highlights how certain diagnoses serve as "multipliers" for financial hardship:

- Cardiovascular Disease: 37% of these patients report struggling with medical bills.
- Mental Health Conditions: 36% report significant struggle, compounded by the often long-term nature of treatment.
- Chronic Complexity: Patients managing three or more distinct health conditions are significantly more likely to cut back on household basics compared to healthy adults (25% vs. 10%).
The "Coverage Gap" and Bureaucratic Denials
Even for those who possess health insurance, the path to care is frequently blocked. The survey highlights a staggering trend of "denial by design." Among insured adults under 65 with three or more chronic conditions, roughly half reported that their insurance company had either delayed or denied coverage for a service or medication that had been explicitly prescribed by their doctor. This issue is pervasive across all chronic categories, with 47% of mental health patients and 45% of cardiovascular patients reporting such denials.
The Uninsured: A Group Left Behind
In a companion column, Dr. Drew Altman, the Founding President and CEO of KFF, argues that the national conversation surrounding healthcare affordability has largely ignored the segment of the population that is suffering the most: the uninsured with multiple chronic conditions.
For these individuals, the system is not merely expensive—it is effectively inaccessible. The data for this group is sobering:
- Financial Ruin: 72% of uninsured adults with multiple conditions report struggling with medical bills, and half have been forced to sacrifice basic household needs to cover medical expenses.
- The Access Gap: They are 20 percentage points more likely to delay care than their insured counterparts (71% vs. 51%).
- Medication Non-adherence: They are twice as likely to skip necessary medications due to cost (51% vs. 24%).
The result is a cycle of neglect. Nearly half (47%) of uninsured adults with mental health conditions report that their health has deteriorated specifically because they were unable to afford or access the care they required.
Official Responses and Expert Perspective
Dr. Drew Altman has been vocal in his critique of the current status quo. Reflecting on the survey results, he noted, "If the first obligation of a health care system is to take care of the sick, we are failing that test. Cost and access problems are hitting the chronically ill hard, and the chronically ill and uninsured especially hard."
Dr. Altman’s analysis suggests that the policy debate in Washington and state houses has focused too heavily on the "average" consumer experience, failing to account for the unique, high-intensity needs of the chronically ill. He is scheduled to address these findings during a keynote address at the National Academy of Medicine’s Annual Meeting this October, where he is expected to call for a recalibration of health policy that prioritizes the most vulnerable patients.

Broad Implications: The Long-Term Costs
The implications of these findings extend far beyond individual suffering. When patients with manageable chronic conditions like diabetes or lung disease are forced to delay care, they do not simply "get better on their own." Instead, they eventually present to emergency rooms in states of acute crisis.
Economic Consequences
The economic burden of this delayed care is eventually absorbed by the system through higher emergency room costs, hospital readmissions, and the loss of workforce productivity. When a patient with a manageable condition sees it progress into a permanent disability, the societal cost—in terms of lost tax revenue, increased social service reliance, and long-term disability payments—far outweighs the initial cost of the medication or treatment they were denied.
The Policy Failure
The KFF survey serves as an indictment of the current insurance landscape. The high rate of "coverage denials" for prescribed treatments suggests that insurance companies are increasingly using administrative hurdles to manage costs, often at the expense of clinical outcomes. As the population ages and the prevalence of multi-morbidity increases, the current model of insurance—which is designed for intermittent, acute care—appears increasingly unsuited for the reality of 21st-century medicine.
Conclusion
The KFF survey of 25,873 adults provides an undeniable look at the human cost of current healthcare policies. By identifying the specific barriers faced by those with multiple or complex conditions, the data makes it clear that the "affordability crisis" is not a uniform experience. It is a concentrated burden that falls most heavily on those who are the least equipped to carry it.
As policymakers look toward the future of the American healthcare landscape, the findings of this report present a clear mandate: the system must evolve to support the chronically ill, or it will continue to face the compounding costs of a sick and increasingly desperate population. Whether through the expansion of coverage for the uninsured or the implementation of stricter regulations regarding insurance denials, the path forward must begin with the acknowledgement that for millions, the system is not just failing—it is currently broken.
