Areas of work: healthcare compliance, FDA regulation, Medicare and Medicaid overpayments

Andrew Hillman's work as an expert witness centers on how regulated healthcare businesses operate day to day. His opinions draw on his years building and running FDA-regulated companies. Counsel retains him in writing, and any expert opinion offered in federal court is subject to Federal Rule of Evidence 702, which governs the admissibility of expert testimony.

The summaries below describe the subject areas he writes and speaks about. They are educational only and are not legal advice.

Healthcare compliance

Healthcare compliance covers the policies, controls and records a provider or manufacturer keeps to meet federal program rules. The HHS Office of Inspector General (HHS OIG) publishes compliance program guidance and enforces fraud and abuse laws. The False Claims Act is the main federal civil statute used when claims paid by federal healthcare programs are alleged to be false. Andrew Hillman writes about compliance patterns and enforcement trends in this area, including how documentation, audits and internal reporting work inside an operating company.

FDA regulation

The FDA regulates drugs, biologics and devices through distinct pathways. One area he writes about is human cells, tissues, and cellular and tissue-based products (HCT/Ps). Products that meet the criteria for regulation solely under section 361 of the Public Health Service Act, such as minimal manipulation and homologous use, follow a lighter framework. Products that do not meet those criteria are regulated as biologics under section 351(a) and generally require FDA approval before marketing. He also writes about FDA filing pathways for early-stage biotech companies, including the chemistry and manufacturing side of a first filing.

Medicare and Medicaid overpayments

The Centers for Medicare and Medicaid Services (CMS) administers Medicare and oversees Medicaid. Under the 60-day overpayment rule, a provider that identifies an overpayment must report and return it within the required time frame. An overpayment that is kept past that deadline can create exposure under the False Claims Act. Andrew J. Hillman writes about how audits, including AI-assisted billing audits, can start that clock.
