Why Has Health Insurance Gone Up: The Real Causes

Health insurance premiums have risen steadily for years, but the recent pace has been sharper than most people expected. The average employer-sponsored plan now costs $8,951 a year for an individual and $25,572 for a family, according to KFF’s 2024 survey. Several forces are converging at once: hospitals are charging more, people are using more medical services than before the pandemic, prescription drug costs are climbing, and the workforce that delivers care is getting more expensive to employ. Here’s a closer look at each driver.

Hospital Prices Are the Biggest Factor

When insurers explain why they’re raising premiums, they point to something called “medical trend,” which is really just two things combined: the prices they pay for healthcare services and how much care their members actually use. Of those two, price is the heavier weight. Hospital costs, particularly the growth in hospitals’ negotiated rates with insurers, are the single largest contributor to premiums for both individual consumers and small employers.

This isn’t a new dynamic. Hospitals have significant bargaining power, especially in regions where one or two health systems dominate. When a hospital system is the only option within a reasonable distance, it can push for higher reimbursement rates during contract negotiations. Those higher rates flow directly into your premium. The growth in these contracted rates has outpaced general inflation for years, and the gap has only widened as hospitals try to recover from financial pressure built up during and after the pandemic.

People Are Getting More Care Than Before

National health spending jumped 7.2 percent in 2024, and a big reason is that Americans are simply using more medical services. Hospital days increased 1.5 percent, hospital discharges rose 3.2 percent, and both the volume and intensity of care across hospitals, physician offices, and pharmacies grew faster than the pre-pandemic average from 2014 to 2019.

Some of this is catch-up. Many people delayed surgeries, screenings, and routine care during the pandemic. But the trend has persisted well beyond what a temporary backlog would explain. An aging population, expanded insurance coverage, and growing demand for behavioral health services are all keeping utilization elevated. More care delivered means more claims filed, which means higher premiums for everyone in the risk pool.

Prescription Drug Costs Keep Climbing

Pharmacy spending is one of the fastest-growing line items on an insurer’s books. Specialty drugs, the expensive medications used for conditions like cancer, autoimmune diseases, and rare genetic disorders, are projected to rise more steeply than any other cost category. These drugs can cost tens of thousands of dollars per patient per year, and the number of people taking them continues to grow.

Newer classes of medication are adding pressure too. GLP-1 drugs, originally developed for diabetes and now widely prescribed for weight loss, have become a significant source of pharmacy spending growth. Gene and cell therapies, while still relatively rare, carry price tags that can exceed a million dollars for a single treatment. Even when only a small number of enrollees use these therapies, the cost is spread across the entire insurance pool.

Healthcare Worker Wages Are Rising

Labor is the single biggest expense for hospitals and clinics, typically accounting for roughly half of total operating costs. Healthcare wages increased 4.3 percent in 2025, accelerating from 2.7 percent the year before. Close to half of healthcare organizations raised their minimum pay rates over the past year, and support staff like clinical technicians saw increases of 5.5 percent.

This wage growth follows a period of intense strain. During the pandemic, hospitals relied heavily on expensive contract nurses and temporary staff. Those costs have moderated, but the baseline for permanent staff wages has shifted permanently upward. Hospitals need to offer competitive salaries to recruit and retain workers in a tight labor market, and those costs get baked into the rates they negotiate with insurers. When comparing labor costs in late 2024 to just two years earlier, the increase was 12.3 percent.

Chronic Disease Drives Most Spending

Ninety percent of the nation’s $4.9 trillion in annual healthcare spending goes toward treating people with chronic and mental health conditions. That single statistic explains more about premium trends than almost anything else. The most expensive conditions are widespread and getting more common:

  • Diabetes costs an estimated $413 billion a year in medical expenses and lost productivity.
  • Heart disease and stroke cost the healthcare system $233.3 billion annually, with projections approaching $2 trillion by 2050.
  • Alzheimer’s and other dementias account for $360 billion in care costs in 2024, expected to nearly triple by 2050.
  • Cancer care is on track to exceed $240 billion by 2030.
  • Obesity adds nearly $173 billion a year to healthcare costs.
  • Arthritis accounts for over $300 billion in medical costs and lost earnings.

These conditions require ongoing management: regular doctor visits, daily medications, lab work, and sometimes hospitalizations. As the population ages and chronic disease prevalence grows, the total cost of insuring a group of people rises, even if no single treatment gets more expensive. Your premium reflects the expected cost of care for everyone in your plan, and the chronic disease burden keeps pushing that number higher.

Providers Are Billing More Aggressively

There’s a subtler factor that doesn’t show up on your explanation of benefits but still affects what you pay. Hospitals and physician groups have become more sophisticated at maximizing reimbursement through coding practices. This means documenting patient visits in ways that qualify for higher payment categories, sometimes called “coding intensity.” It’s not necessarily fraud. It often reflects more thorough documentation of conditions that were always present. But the financial effect is real: insurers pay out more per visit, and those costs get passed along in premiums.

Providers argue they need every dollar they can get. Operating costs have risen faster than what insurers have been willing to pay in recent years, squeezing hospital margins. From the provider side, more aggressive billing is a survival strategy. From the insurer side, it’s another cost to absorb or pass on to you.

Why It All Hits at Once

What makes the current moment feel especially painful is that none of these factors exist in isolation. Hospitals are charging more because their own costs are up. Drug spending is rising because new, expensive therapies are reaching more patients. Utilization is elevated because more people have coverage and the population is aging. Healthcare wages are climbing because the labor market demands it. Each of these pressures feeds into the others, and insurers respond the only way they can: by raising premiums.

Federal rules do place some guardrails on how insurers spend your money. Under the Affordable Care Act, insurance companies must spend at least 80 to 85 percent of premium dollars on actual medical care rather than administrative costs or profits. If they fail to hit that threshold, they owe you a rebate. But that rule doesn’t cap the total amount of the premium. It just ensures that when prices go up, it’s mostly because the cost of care went up, not because the insurer is pocketing more.

The upward pressure on premiums is broad, affecting commercial plans, Medicare Advantage, Medicaid managed care, and marketplace plans alike. As one credit rating analyst put it, the cost trends “are not isolated.” They’re showing up across nearly every major line of business in health insurance.
