Payer Behavior Is A Large Threat to Hospital Revenue… And Most Teams Aren't Ready

Key Takeaways

•  Nearly two-thirds of RCM leaders now identify payer-driven denials and underpayments as their #1 barrier to revenue growth in 2026.

•  Claim denial rates industry-wide are running above 15%, and 60% of denied claims are never resubmitted, which represents billions in abandoned revenue.

•  Silent underpayments, claims paid below contracted rates with no denial letter, are the fastest-growing source of undetected revenue loss.

•  ERISA-governed self-funded plan claims carry a unique federal recovery pathway that most hospital billing teams never pursue.

•  Internal teams are already strained. Recovery of complex, aged, and zero-balance claims requires specialized outside expertise.

The Conversation Has Changed: Payers Are Now the Biggest Financial Risk

For years, the conversation in hospital revenue cycle management focused on internal performance like clean claim rates, days in A/R, staffing efficiency. But 2026 has brought a significant shift. According to a new benchmark study, nearly two-thirds of RCM leaders now identify payer-driven denials and underpayments as their single largest barrier to revenue growth which surpasses internal challenges for the first time. Payer behavior, not internal process gaps, has become the defining financial risk for hospitals and health systems this year. That shift has real consequences for the bottom line.

The Numbers Are Difficult to Ignore

Industry data indicates that claim denial rates are running at 15% and higher across the industry, with some specialties seeing even higher rates. Hospitals spent an estimated $19.7 billion in a single year attempting to overturn denied claims, and that does not account for the revenue that simply disappears because 60% of denied claims are never resubmitted at all. Beyond outright denials, payers are increasingly adjusting adjudication rules and fee schedules in ways that create systematic underpayments… payments that close accounts without triggering a denial workflow, making them nearly invisible to standard follow-up processes. The result is a revenue environment where hospitals are routinely paid less than they are contractually owed, and most do not have the systems in place to detect or recover it.

ERISA Claims: A Hidden Pool of Recoverable Revenue

The challenge is compounded by the nature of the claims most at risk. Complex claims, particularly those tied to self-funded employer health plans governed by federal ERISA law, fall outside standard state insurance regulations and require a different recovery approach entirely. These claims often age past the point where conventional billing follow-up workflows reach them, get written off as bad debt, and are never revisited. Yet ERISA's civil enforcement provisions create federal recovery pathways that most hospital RCM teams are either unaware of or do not have the expertise to pursue. For many health systems, this represents a significant pool of recoverable revenue sitting in their zero-balance accounts.

Work Smarter, Not Harder

RCM leaders are under increasing pressure to respond, but the path forward is not simply working denials harder or faster. The data shows that most RCM teams are already spending between 51 and 75 hours per week on denial-related work. Adding volume to an already strained team is not a sustainable strategy. What health systems need is specialized expertise applied specifically to the claims that are most complex, highest in dollar value, and least likely to be recovered through standard workflows: ERISA claims, aged accounts, underpaid self-funded plan claims, and zero-balance accounts that were closed prematurely.

How ERISA Recovery Can Help

ERISA Recovery specializes in the claims that fall through the cracks of conventional revenue cycle operations, such as denied claims, aged accounts, complex self-funded plan claims, and zero-balance accounts that closed without full payment. Our team brings deep expertise in federal ERISA law and payer-specific recovery strategies, allowing hospital revenue cycle teams to recover revenue they have already written off without adding to their internal workload. As payer behavior continues to drive financial pressure across the industry, having a specialized recovery partner is no longer a luxury… it is a strategic necessity.
