Medicare and Medicaid Fraud Enforcement History
At Barrett Johnston, we’ve seen firsthand how the federal government’s approach to Medicare and Medicaid fraud has evolved from modest oversight to one of the most sophisticated enforcement systems in the world—albeit a system that is still limited in its ability to stop fraud, waste, and abuse. Understanding that history helps explain why today’s whistleblowers are so essential to protecting these programs.
Medicare and Medicaid were established in 1965 to provide healthcare for older adults, people with disabilities, and low-income individuals. But from the very beginning, fraud and abuse emerged as major concerns. In the 1970s and 1980s, schemes like phantom billing, upcoding, and unnecessary procedures began drawing attention from investigators.
To respond, Congress passed laws such as the False Claims Act amendments of 1986, which empowered whistleblowers to report fraud and share in government recoveries. Throughout the 1990s and 2000s, landmark cases against hospitals, pharmaceutical companies, and healthcare providers demonstrated the enormous scale of the problem — and the power of enforcement.
Modern fraud enforcement is spearheaded by the Department of Justice (DOJ), the Office of Inspector General (OIG), and the Centers for Medicare & Medicaid Services (CMS). These agencies collaborate on audits, investigations, and recoveries that have returned billions of dollars to the Medicare Trust Fund each year.
Today, whistleblowers remain at the heart of this system. Their willingness to step forward continues to shape the next chapter in Medicare and Medicaid fraud prevention.
The launch of Medicare and Medicaid in 1965 brought immediate enforcement concerns because the programs prioritized beneficiary access over built-in payment safeguards. That tradeoff created serious vulnerabilities from day one.
– The fee-for-service model encouraged high-volume billing with very few prepayment reviews, meaning suspect claims often got paid first and investigated later
– Provider enrollment standards were minimal, allowing unqualified operators and fly-by-night clinics to enter the system easily
– State and federal agencies lacked shared data systems, so fraudulent billing in one state went undetected when the same actor moved operations elsewhere
Investigators in the 1970s and 1980s began documenting specific abusive practices that exploited the payment system’s trust-based design. These schemes moved beyond simple overbilling into organized, repeatable fraud patterns.
Most commonly:
– Laboratory and durable medical equipment companies paid kickbacks to physicians for patient referrals, disguising them as rental fees or consulting arrangements
– Providers billed for medically unnecessary tests and procedures, often targeting nursing homes and home health agencies where oversight was weakest
– Some operators submitted claims for equipment or services never delivered, using patient rosters stolen from hospitals or obtained through patient brokering
The 1986 amendments revitalized the False Claims Act as the primary weapon against healthcare fraud by dramatically strengthening the qui tam provisions.
They increased whistleblower reward shares up to 30 percent and lowered the intent standard to include reckless disregard or deliberate ignorance, not just actual knowledge. The amendments also narrowed the public disclosure bar, allowing more private suits to proceed even when information had entered the public domain. Penalties per claim rose substantially, creating real financial deterrence.
These changes shifted enforcement from a passive government function to an active, whistleblower-driven model that fundamentally increased case volume and recoveries.
The landmark cases of the 1990s and 2000s revealed that healthcare fraud was not limited to small players but permeated the largest hospital chains and pharmaceutical companies. The government uncovered systematic schemes involving kickbacks for referrals, fraudulent drug pricing, and inflation of hospital cost reports.
– These cases showed that fraud often involved sophisticated accounting maneuvers, such as shifting costs between departments to maximize Medicare reimbursement.
– They also demonstrated the power of whistleblowers in exposing widespread, long-running fraud that would otherwise remain hidden.
Modern enforcement is led by a partnership of federal agencies.
– The Department of Justice (DOJ) prosecutes civil and criminal fraud cases
– The HHS Office of Inspector General (HHS-OIG) investigates fraud and can exclude bad actors from federal programs
– The Centers for Medicare & Medicaid Services (CMS) administers the programs and uses data analytics to prevent fraudulent payments
– The FBI also investigates healthcare fraud schemes
These agencies collaborate through joint task forces and the Health Care Fraud and Abuse Control Program (HCFAC).
In FY 2023, the Medicare Trust Funds received approximately $974 million in transfers from enforcement efforts, part of over $3.4 billion returned to the federal government that year.
Since the Health Care Fraud and Abuse Control Program began in 1997, it has returned over $8.85 billion to the Trust Fund.
Recent years have seen substantial recoveries, with DOJ False Claims Act settlements and judgments exceeding $2.68 billion in FY 2023, much of it from healthcare fraud.
Whistleblowers are essential because government auditors cannot monitor every claim, and insiders possess the specific knowledge needed to prove fraudulent intent. Their firsthand access to billing records, internal emails, and referral patterns often makes or breaks a case.
– Whistleblowers file the vast majority of healthcare fraud suits under the FCA, with DOJ reporting that relators initiated over 80 percent of recent healthcare cases
– They shorten investigation timelines by providing concrete evidence, reducing reliance on lengthy subpoena-driven discovery
– Their financial stake through qui tam rewards creates a powerful incentive to come forward, sustaining enforcement when government resources are stretched thin
