Healthcare Revenue Integrity: The Perfect Storm of Surging Denials and Audits, Greater Scrutiny

By Ritesh Ramesh, CEO, MDaudit.

Healthcare organizations are engulfed in an intensifying storm of audits and denials exacerbated by heightened regulatory and payer scrutiny. Individually, any of these trends can endanger a hospital’s or health system’s financial stability. Combined, they represent a crisis calling for immediate action.

Healthcare finance leaders who wish to successfully guide their organizations across this increasingly complex and challenging landscape must transform their revenue cycle management (RCM) strategies. Central to this transformation is proactive risk monitoring and the implementation of AI-driven compliance strategies.

Mounting Pressure

According to the 2024 MDaudit Annual Benchmark Report, audit volumes more than doubled over 2023 rates while total at-risk dollars increased fivefold to $11.2 million, straining provider organization cash flows. That analysis, encompassing more than $8 billion in audited professional and hospital claims and over $150 billion in denials collected from more than 650,000 providers and more than 2,200 facilities, also found that payer scrutiny is at an all-time high.

Medicare Advantage (MA) plans are a favorite target, with HCC and RADV audits—which help ensure health plans and providers are paid appropriately based on the actual health of their members—rising by 72% and total MA denials by 51%. Denials related to how providers code their claims increased by 126%, representing one of the most significant increases in the last three years. Denials surged across care settings; hospital inpatient-related denials were up nearly 220% to $10,000 per claim, hospital outpatient by 32.5% to $825, and professional by 24% to $140.

While the data clearly demonstrates that coding integrity is one of the biggest revenue optimization opportunities in healthcare, documentation around the medical necessity of care provided also urgently needs improvement. The MDaudit analysis revealed a 140% increase in total denial amounts for inpatients and a 75% increase in outpatient amounts related to the “Medical Necessity and Information Needed” category. Overall, more claims dollars were denied in 2024 by Medicare and commercial payers due to a lack of information submitted for the service and medical necessity, driving an increase in final denial dollars across professional (34%), hospital outpatient (84%), and hospital inpatient (148%).

Behind these increases was a doubling of external audit volumes, which included a sizable jump in pre-payment audits. These audits can interfere with cash flow and increase overall denial rates.

Fraud prevention is adding to the complexity of today’s healthcare financial landscape. According to the US Department of Health and Human Services (HHS) Office of the Inspector General (OIG) Health Care Fraud and Abuse Control Program Report for Fiscal Year (FY) 2023, released in December 2024, federal recovery efforts targeted $4.7 billion in projected overpayments within MA alone, a figure expected to rise as the Centers for Medicare and Medicaid Services (CMS) ramps up fraud prevention.

Fiscal year 2023 saw civil healthcare fraud settlements and judgments under the False Claims Act exceed $1.8 billion, bringing the total amount returned to the federal government or paid to private individuals to more than $3.4 billion. This figure includes $974 million returned to the Medicare Trust Funds and $257.2 million in federal Medicaid funds transferred separately to the CMS.

Transforming RCM Strategies

The shift toward more aggressive pre-payment audits, a greater focus on fraud, and tactics to prolong reimbursement delays underscore the need for a revenue strategy that prioritizes revenue optimization and risk mitigation. Built upon a foundation of AI, automation, and other technology tools that enable continuous monitoring of real-time financial risk based on payer trends and denial management, this transformative revenue cycle strategy delivers a significant return on investment (ROI). It also introduces automated workflows that drive operating margins.

Streamlining and improving audit response is essential for enhancing providers’ revenue capture, particularly as payer organizations increasingly rely on pre-payment audits to delay reimbursements and increase denial rates. Investing in AI, machine learning (ML), and automation tools that deliver intelligent functionality to automate and accelerate the management of external payer audits ensures the timely processing of additional documentation requests (ADRs), thereby improving audit defense outcomes and revenue retention.

Generative AI and natural language processing (NLP) solutions further optimize audit outcomes by unlocking insights and patterns from historical data while also increasing accessibility and democratizing information across the revenue cycle. For example, generative AI tools that take natural language questions and instantly compute complex formulas to return clear, concise, and actionable responses boost human productivity and deliver speed-to-value. They eliminate information silos between revenue integrity and executive teams, transforming how they interact with data to make more innovative and strategic decisions.

Transforming the Revenue Cycle

Strong internal compliance programs and a cross-functional operating model that connect the dots between billing, coding, CDI, and revenue integrity will advance a unified revenue retention and growth agenda. Leveraging data and insights as a storytelling mechanism enhances program value by removing bias and injecting objectivity into discussions and decision-making while establishing success metrics introduces accountability for tangible outcomes.

With the core strategy in place, finance executives can look to other targets for RCM transformation to enable healthy operating margins, such as high-value outpatient services like elective surgeries and some inpatient services. Along with scrutinizing complex services, other opportunities to improve revenue retention include implementing clinical documentation improvement (CDI) programs that drive outcomes tied to RCM and denial management metrics.

CDI, billing, coding, and RCM programs can also be tightly coupled to implement a closed feedback loop from the backend to the mid-cycle, driving efficiencies. Finally, automate coding operations and increase the utilization of AI-powered systems that amplify errors at scale while keeping humans in the loop.

Deploying technologies that bridge mid-cycle and back-end functions will drive more substantial margins and cash flow while mitigating risks tied to payer-driven policies and denials. An aggressive AI-enabled, data-driven, and people-led approach to the revenue cycle allows forward-looking finance leaders to position their organizations for financial survival in today’s high-risk landscape.
