Stopping Soaring Stop-Loss Rates

By: David Ostrowsky

As employers across a wide swath of industries gravitate towards adopting self-funded health plans, the demand for stop-loss protection has naturally mushroomed. After all, an employer going down the self-funded road that passes on stop-loss is taking on a scary amount of risk in the event that it incurs a devastating claim. And it’s a vicious cycle: With the subsequent pent-up demand for stop-loss policies, carriers are hiking up rates, meaning the costs for self-funding in general are rising . . . and rising. Indeed, employers with self-funded plans are experiencing severe sticker-shock this renewal season as prices continue spiraling out of control and there appears to be no end in sight.

Just how bad is it? Going into 2026, healthcare experts forecasted double-digit spikes in average stop-loss premiums. Their predictions weren’t foolhardy. As the second quarter of 2026 unfolds, many employers are staring down stop-loss rates that have ballooned over 20 percent. Executives at Voya Financial, one of the country’s preeminent financial services companies, recently shared that it escalated stop-loss prices by an average of 24% for employers renewing their coverage on January 1. Apparently, this troubling trend is expected to continue in the years ahead as, courtesy of Allied Market Research, a stop-loss insurance market valued at $26.9 billion in 2024 is projected to reach $113.5 billion by 2034.

Why are stop-loss policies shooting northward with astonishing rapidity at this particular moment in time? Some of the core reasons include:

• A recent surge of unpredictable, high-cost claims, driven by an onrush of new FDA-approved cellular therapies. Cell therapies—which, of course, often carry a hefty price tag—are being approved at a breakneck pace and are increasingly being incorporated into earlier lines of therapy, particularly for blood cancers. Additionally, cell therapies have become more accessible to a broader patient population thanks to improved manufacturing processes and the fact that they’re no longer restricted to inpatient hospital settings.
• Meanwhile, claims for specialty drugs, including the ever-expensive GLP-1 drugs, are bountiful while the volume of neonatal and cancer claims continues rising. The bottom line: Heretofore catastrophic and infrequent claims have now become more commonplace, spurring many stop-loss carriers to implement more stringent underwriting rules and, yes, hike rates. Just one example: According to the March 2026 edition of The Self-Insurer, the financial services company Sun Life reported that employers saw a 29% increase in claims for $1 million or more per million covered employees in 2024 compared to the year before—and a 47% increase in claims totaling $3 million or more.
• Medical inflation. In the post-COVID world, medical costs, whether they be for hospital care, physician services, or prescription drugs, are soaring higher and higher. Just like groceries and airline tickets, surgeries are getting more expensive as we speak.

Is this situation beyond the control of self-funded employers? Are there any steps they can take to manage costs for stop-loss premiums when they become renewable?

In short, self-funded employers can and should devise a strategic game plan to steer participants towards less expensive—but still high-quality—providers and facilities to mitigate financial burdens. Making prudent cost containment decisions—remembering that the most expensive facilities don’t necessarily offer the best care—and executing proactive health management strategies has never been more critical. Self-funded employers can ensure their employees are engaged consumers of healthcare by championing wellness programs, helping to pre-emptively manage chronic conditions in order to avoid long-term complications, and providing preventive care incentives, such as those for annual screenings and/or physicals. It may sound obvious and trite, but early detection of underlying conditions can prevent unimaginably expensive treatment for late-stage diseases—and subsequently higher stop-loss rates.

In an ever-complex stop-loss marketplace, let the latest and greatest technology work in your favor. For seemingly ever, risk management in the self-funded healthcare industry has been grounded in lagging indicators, manual analysis, and sweeping generalizations. But with the advent of artificial intelligence (AI), advanced analytics, predictive modeling, and machine learning, employers can become more proactive by leveraging in-depth data-driven insights into their respective populations towards blueprinting enhanced benefit structures. Additionally, through demonstrating dynamic risk management and optimization,  they may find themselves better positioned to negotiate more favorable stop-loss terms, including rate caps or restrictions on how much premiums can increase at renewal. Likewise, having such resources at one’s disposal may help inhibit carriers from adding specific exclusions for high-cost members at renewal, often termed “no new lasers.”

So, in other words, stop-loss premiums may be at historically high levels but, as always, there are still opportunities for keeping high-dollar medical claims in check, which can (at least partially) offset the drastic price increases.
