The Change Healthcare cyberattack of 2024 was supposed to be a wake-up call. Instead, it appears to have been largely ignored. Two years after the incident devastated healthcare operations nationwide, the fundamental infrastructure vulnerabilities that made the breach so catastrophic remain largely unaddressed, creating systemic risk across the entire healthcare ecosystem.
The incident wasn't simply a cybersecurity problem—it exposed a deeper architectural flaw in how American healthcare processes claims and manages critical workflows. Change Healthcare's dominant position in the clearinghouse market meant that when attackers shut down their systems, hundreds of health systems simultaneously lost their ability to submit claims, verify eligibility, and manage patient billing. For weeks, hospitals and practices operated partially blind, unable to process vital transactions that keep revenue flowing and care coordinated.
What makes this situation particularly concerning is the lack of meaningful progress toward redundancy. Clearinghouses act as crucial intermediaries between providers, payers, and government programs—processing billions of transactions annually. Yet the market structure that created this vulnerability persists. Few health systems have implemented secondary clearinghouse relationships or geographic failover capabilities. Many remain dependent on single-vendor solutions for mission-critical processes, betting that a repeat catastrophe simply won't happen.
The Economics of Inaction
This inertia isn't purely negligent. Implementing true redundancy requires significant investment in IT infrastructure, staff training, and workflow redesign. For financially strained health systems, the business case for redundancy competes against immediate operational needs and clinical priorities. Without regulatory mandates or payer enforcement mechanisms requiring failover capabilities, many organizations have taken a calculated risk that they can weather another outage.
Meanwhile, vendors face limited incentives to facilitate interoperability that would make switching clearinghouses easier. The friction of integration creates customer lock-in—a dynamic that persists in healthcare technology broadly. Until health systems can seamlessly failover to alternative clearinghouses without operational disruption, few will invest in redundancy.
For health system leaders, this represents an underappreciated governance and operational risk. The Change incident demonstrated that claims processing disruptions cascade rapidly through patient care operations, affecting billing, revenue cycle management, and ultimately clinical workflows. Yet many organizations' disaster recovery plans still don't adequately address clearinghouse failure scenarios.
Vendors and health IT consultants have an opportunity to address this gap, but it requires moving beyond point solutions toward infrastructure resilience. Those companies offering integrated secondary clearinghouse connectivity, automated failover capabilities, and easier vendor switching are positioning themselves as solutions to a problem many health systems have yet to fully acknowledge.
The healthcare industry's collective failure to build redundancy into critical infrastructure two years after a high-profile breach suggests deeper challenges with how the sector approaches operational resilience. Until regulatory bodies mandate redundancy requirements or payers enforce them as contract terms, health systems will continue operating with infrastructure that's one catastrophe away from widespread failure.
The question isn't whether another major clearinghouse incident will occur—it's whether the industry will finally act before it does.
