Government Experience, Bespoke Advocacy in Healthcare Litigation
Overview
AGG has assembled one of the deepest benches of high-ranking former government attorneys in the industry, bringing their unique government insights, contacts, and skills to bear for our clients, whether it’s defending or going on the offensive in healthcare litigation matters involving federal agencies. AGG’s Healthcare Litigation team includes former senior attorneys from the U.S. Department of Justice, the Department of Health and Human Services, the Office of Inspector General, and the Centers for Medicare & Medicaid Services, offering clients the strategic advantage of firsthand agency insight. We understand how enforcement decisions are made, how regulatory disputes unfold, and what arguments resonate with the government — because we’ve made them ourselves.
Our clients often face scrutiny from the same agencies we once served. Whether the matter involves False Claims Act allegations, OIG subpoenas, CMS recoupments, or state-level Medicaid actions, our attorneys deliver informed advocacy that anticipates regulator behavior and reduces exposure.
