For years, healthcare organizations have approached Medicare fraud and billing compliance as primarily a retrospective exercise. Claims are submitted, payments are made, audits follow, and organizations investigate problems after they surface.
That model is becoming increasingly unsustainable.
The federal government is moving toward a more aggressive approach to Medicare program integrity, using data analytics, artificial intelligence (AI), and machine learning to spot suspicious billing patterns earlier and, in some cases, prevent improper payments before they are made.
CMS has made the direction clear. In August 2026, the agency said its enforcement actions had stopped more than $1.6 billion in potentially improper Medicare laboratory payments since the beginning of the Trump administration. The effort included using AI and machine-learning models to analyze Medicare fee-for-service claims, identify unusual billing patterns, and flag high-risk claims for further review.
In September 2026, CMS announced another major enforcement action involving 11 medical equipment suppliers associated with more than $3.4 billion in suspected fraudulent Medicare Advantage and Part D billing. The agency said data analytics helped identify suppliers billing for equipment involving deceased beneficiaries and other suspicious activity.
This is more than an escalation of traditional fraud enforcement. It’s a fundamental change in the timing of the fight. The question for healthcare organizations is no longer simply whether they can respond effectively when an auditor finds a problem. It is whether they can identify the same risks before increasingly sophisticated government enforcement does.
From “Pay and Chase” to Continuous Detection
The traditional model of program integrity has often been characterized as “pay and chase,” which involves identifying a claim, paying it, discovering a problem later, and attempting to recover the money. Technology is changing that equation. CMS has explicitly described its current approach as using data-driven prevention and real-time enforcement. Its fraud initiatives increasingly combine claims data, provider information, utilization patterns, and other signals to identify anomalies before improper payments occur.
The agency’s Wasteful and Inappropriate Service Reduction, or WISeR, model provides another example. CMS is using AI and machine learning with human clinical review to evaluate certain services vulnerable to fraud, waste, and inappropriate utilization. For providers, this creates a different compliance environment.
A billing pattern that once might have survived for months before appearing in an audit can increasingly be identified through continuous analysis. A provider may not receive a warning that a pattern has become risky. The first indication could be a claim being held, denied, or referred for investigation.
That changes the role of revenue integrity.
The Risk Is Already Showing Up in Provider Data
External enforcement is growing more sophisticated as providers face increasingly aggressive scrutiny of their own claims. Our analysis shows how quickly audit exposure is changing. For example, we’re seeing a 30% increase in external payer audit risk, while the average amount at risk per claim increased 18%. HCC audits increased 102%, and the report also documented a 26% increase in coding denials.
The significance isn’t simply that more claims are being audited. The financial consequences of waiting to discover problems after submission are growing.
Organizations can no longer treat revenue integrity as a periodic exercise performed when an audit arrives. The risk increasingly exists at the point where documentation, coding, and claims are generated. That makes continuous visibility increasingly important.
Compliance Has to Move Upstream
The logical response isn’t to build a larger team to chase denials and respond to audits. It is to move the detection process closer to the point where risk is created. That means analyzing claims before submission, identifying unusual coding patterns, comparing provider behavior against relevant benchmarks, and looking for documentation or medical-necessity issues. At the same time, there is still time to correct them.
AI can help with that work because the volume of healthcare data makes purely manual approaches increasingly impractical.
But AI should not be viewed as a replacement for coding, compliance, or clinical expertise. Its value is in helping organizations identify where human attention is most needed. An effective system can continuously examine large volumes of claims and surface patterns that would be difficult for an individual reviewer to recognize. A compliance professional can then investigate the finding, determine whether there is a legitimate explanation, and decide on appropriate action.
The result is a shift from reviewing everything to intelligently prioritizing what deserves attention.
The Emerging AI Arms Race
This is where the issue becomes bigger than fraud prevention. If regulators use increasingly sophisticated technology to identify patterns in healthcare claims, providers and health systems need to understand their own data at the same level. Otherwise, there is an asymmetry.
One side can continuously analyze millions of claims for anomalies while the other relies primarily on periodic audits, spreadsheets, and retrospective reviews. That is not a sustainable compliance strategy.
The organizations best positioned for this environment will use technology to continuously monitor their revenue cycle and billing behavior, identify emerging risks, and intervene before those risks become denials, repayment demands, or investigations. In other words, the goal isn’t simply to beat an audit.
It is to make sure the organization can see what the auditor is likely to see before the auditor does.
Humans Still Have to Make the Call
An important distinction exists between using AI to identify risk and allowing AI to determine that fraud has occurred. Healthcare billing is complicated. A statistical anomaly isn’t necessarily an error, and an unusual claim isn’t necessarily fraudulent.
A sophisticated revenue-integrity program therefore needs a human review layer. AI can pinpoint patterns. It can prioritize claims. It can connect information across enormous datasets. But experienced compliance, coding, and clinical professionals still need to determine what those patterns mean.
That matters more as healthcare organizations adopt AI for higher-stakes compliance functions. The objective should not be to automate judgment.
It should be to give the people responsible for that judgment better information, sooner.
The New Definition of Preparedness
CMS’s recent actions suggest that the federal government’s approach to Medicare fraud is moving toward continuous detection, data-driven enforcement, and earlier intervention in the payment process.
Providers should expect that trend to continue. That means preparedness can no longer be defined simply by having a compliance program, conducting periodic audits, or responding quickly when an external payer raises a concern.
Preparedness increasingly means knowing what is happening inside the organization’s claims data every day. The Medicare fraud fight is becoming an AI arms race. Regulators are using technology to find suspicious patterns faster, connect signals across enormous datasets, and stop questionable payments before they leave the system. Healthcare organizations don’t necessarily need to outspend or out-tech the government.
But they do need enough visibility into their own data to recognize risk before someone else does. Organizations that make that transition will be in a much stronger position not only to defend revenue, but to show their billing methods are accurate, defensible, and compliant before an outside party comes asking questions.
