White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Few enforcement actions carry consequences as immediate and far-reaching as investigations and penalty proceedings initiated by the HHS Office of Inspector General (OIG). Allegations that place Civil Monetary Penalties (CMPs) on the table do more than threaten fines—they put careers, licenses, federal program participation, and reputations at serious risk.
For healthcare providers, suppliers, executives, and organizations operating in federally funded programs, these matters demand a swift, strategic, and highly experienced response. At Chapman, Dowling & Mallek, we defend clients nationwide against OIG and HHS enforcement actions with one objective in mind: protecting your ability to practice, operate, and move forward with your reputation intact.
From a legal standpoint, OIG & HHS CMP defense is not a single event—it is a multi-stage process that often begins quietly and escalates quickly. Effective defense requires precision, deep regulatory fluency, and an understanding of how government enforcement teams actually build their cases.
Our representation typically includes:
Strategic Case Analysis
We conduct an immediate, line-by-line review of Notices of Proposed Determination (NPDs), Civil Investigative Demands (CIDs), subpoenas, and audit findings to identify statutory exposure, evidentiary weaknesses, and leverage points.
Internal Investigations & Evidence Development
Our team works with providers and organizations to reconstruct billing decisions, referral relationships, and operational practices—often before the government completes its theory of liability.
Regulatory & Statutory Defense
We apply advanced knowledge of the Anti-Kickback Statute, Stark Law, False Claims Act, Civil Monetary Penalties Law, and CMS regulations to challenge overreach, misinterpretation, and inflated damage calculations.
Negotiation & Resolution Strategy
Many CMP cases are resolved long before formal litigation—if handled correctly. We engage directly with OIG and HHS enforcement counsel to pursue reduced penalties, structured resolutions, or complete declination where possible.
Administrative Litigation & Appeals
When resolution is not appropriate or offered on acceptable terms, Chapman, Dowling & Mallek aggressively represents clients before Administrative Law Judges (ALJs), the Departmental Appeals Board (DAB), and—when necessary—federal court.
Compliance Remediation & Risk Containment
We advise on corrective action plans, compliance enhancements, and forward-looking safeguards designed to prevent repeat exposure and avoid future enforcement.
Our goal is always the same: to reduce or eliminate CMPs while preventing collateral consequences such as program exclusion, corporate integrity agreements, or parallel criminal exposure.
CMP enforcement actions arise from a wide range of alleged conduct, including:
In many cases, enforcement actions stem from audits, whistleblower allegations, or data analytics—not intentional fraud. That distinction matters, and it is often the foundation of an effective defense.
Civil Monetary Penalties cases are rarely handled by a single agency. Investigations often involve coordinated efforts among:
Understanding how these agencies collaborate—and where authority overlaps—is essential to controlling the trajectory of an enforcement action.
CMP exposure extends far beyond financial penalties. Potential consequences include:
For many providers, exclusion—not fines—is the true existential threat.
Effective defense requires mastery of the statutes that enforcement agencies rely upon, including:
These laws operate together, allowing civil enforcement to escalate quickly if not addressed with precision.

Healthcare professionals and organizations trust us because we understand federal enforcement tactics, move quickly to protect careers and licenses, and focus on achieving the best possible outcome with minimal disruption to professional and business operations.
OIG and HHS enforcement is unforgiving, highly technical, and deadline-driven. Providers who attempt to respond without experienced counsel often unknowingly concede liability or worsen their exposure.
At Chapman, Dowling & Mallek, we bring a federal-level defense mindset to every CMP matter—focused on quiet resolutions where possible and aggressive litigation when necessary. We understand how regulators think, how cases are built, and how to protect what matters most: your career, your organization, and your future.
If you are facing OIG or HHS scrutiny, early intervention can make the difference between resolution and irreversible damage.
Government & Regulatory Resources:
Defense in cases involving healthcare fraud, false claims, and regulatory violations.
Quiet. Strategic. Decisive.
Every federal case is built long before the courtroom—and often ends before it ever reaches one. Led by a former federal prosecutor and U.S. Marine Corps Judge Advocate—supported by former federal investigators—our process is designed to resolve matters quietly, strategically, and with precision.
We engage early, often before formal charges are filed. By understanding how federal agencies build cases, we work to shape the investigation, limit exposure, and control the narrative from the start.
Our credibility and insight into federal procedure allow us to communicate effectively with prosecutors and investigators—often achieving resolution through dialogue rather than litigation.
We combine investigative experience with advanced data analytics and AI to uncover patterns, test government theories, and identify weaknesses in complex financial, digital, or regulatory evidence.
Whether through negotiation or trial, our approach is tailored to secure the best outcome — quietly, strategically, and decisively, with every step focused on protecting our clients’ reputations and results.
