Practice Concentration and Experience:

Charles Grant is a partner in the Washington, D.C., office of Liles Parker where he specializes in healthcare fraud, waste, and abuse; exclusions appeals; psychedelic medications; and expert witness testimony. He was previously a Senior Counsel and Exclusions Director at U.S. HHS Office of Inspector General (OIG).

Prior to joining Liles Parker, Mr. Grant spent 20 years in various capacities at HHS, primarily in the area of government-funded healthcare programs, rising to the position of Senior Counsel in the Office of Counsel to the Inspector General (OCIG) in the Office of Inspector General (OIG).

He served as one of two Exclusion Directors in the OIG Office of Investigation (OI). During his tenure, he reviewed and processed well over 16,000 exclusions. He oversaw the development and implementation of sanctions in the form of exclusions of providers from government-funded healthcare programs in order to combat fraud, waste, and abuse; ensure the integrity of the programs, and protect program beneficiaries from untrustworthy individuals and entities as well as unnecessary and/or unprofessional care. He supervised and managed a national staff, directing and coordinating exclusions casework activities and providing direction and guidance. In consultation with the Office of Counsel to the Inspector General, he rendered opinions and guidance as to the legal sufficiency of the exclusion actions based on applicable statutes, regulations, and court decisions; presented speeches to professional organizations on fraud, waste, and abuse and the bases and effects of exclusions from federally-funded healthcare programs; and assisted the Department of Justice and other entities in criminal prosecutions of healthcare fraud, waste, and abuse, including testifying as an expert witness at trial.

With the transfer of exclusions from the Office of Investigations to OCIG, he became a Senior Counsel and a member of the newly-created Special Exclusions Team. In that capacity, he located, researched, and reviewed potential exclusions cases and determined their legal sufficiency for exclusion. He also represented the Department in exclusion appeals. In addition, he continued to conduct outreach, giving exclusions presentations to numerous state and federal organizations including the Department of Defense, and various state insurance commissions, as well as state attorney and district attorney offices, and to assist the Department of Justice and HHS OIG agents in the development of health care cases.

Prior to joining the Office of Inspector General, Mr. Grant spent six-and-a-half years as a Health Insurance Specialist at the Center for Medicare and Medicaid Services (CMS). He served on procurement panels for various departmental initiatives, negotiated and oversaw over $80 million in Medicare contracts, reviewed and analyzed policy statements and other documentation, and advised staff on the ramifications of agency policy. He also managed and coordinated the project planning for procurements for the Health Information Technology for Economic and Clinical Health (aka “HITECH”) portion of the American Relief and Recovery Act of 2009 (“ARRA”) and reviewed proposed legislation dealing with the adoption of electronic health records by providers.

Before entering the government, he was an attorney in the private sector. His practice included administrative law, litigation, contracts, business and corporate law, employment and labor law, entertainment and intellectual property, and criminal defense. He was lead counsel in more than 700 cases in state and federal courts. In all criminal matters, the opposing counsel was the United States Attorney’s Office. Before becoming an attorney, Mr. Grant spent several years as a financial analyst in both the public and private sectors in New York City.
