Regulation
| We are subject to extensive and frequently changing laws and regulations in the United States (at both the federal and state levels) and other jurisdictions in which we conduct business, and to government inspections and audits. | |
|---|---|
| Key Regulatory Schemes | |
| CLIA and State Clinical Laboratory Licensing | CLIA regulates the operations of virtually all clinical laboratories, including our laboratories in the United States, requiring that they be certified by the federal government and that they comply with various technical, operational, personnel and quality requirements intended to ensure that the services provided are accurate, reliable and timely. CMS, as a federal agency administering CLIA, also requires compliance with applicable federal human subject protection requirements, including the Common Rule, which establishes baseline protections such as institutional review board oversight and informed consent, when laboratory activities involve human subjects. State laws may require additional personnel qualifications or licenses, quality control, record maintenance, proficiency testing or detailed review of our scientific method validations and technical procedures for certain tests. Violations of these laws and regulations may result in monetary fines, criminal and civil penalties and/or suspension or exclusion from participation in Medicare, Medicaid and other federal or state healthcare programs. |
| Medicare and Medicaid; Fraud and Abuse | Diagnostic testing services provided under Medicare and Medicaid programs are subject to complex, evolving, stringent and frequently ambiguous federal and state laws and regulations, including those relating to billing, coverage and reimbursement. Anti-kickback laws and regulations prohibit making payments or furnishing other benefits to influence the referral of tests billed to Medicare, Medicaid or certain other federal or state healthcare programs. In addition, federal and state anti-self-referral laws generally prohibit Medicare and Medicaid payments for clinical tests referred by physicians who have an ownership or investment interest in, or a compensation arrangement with, the testing laboratory, unless specific exceptions are met.Some states have similar laws that are not limited in applicability to only Medicare and Medicaid referrals and could also affect tests that are paid for by health plans and other non-governmental payers. If these laws and regulations are interpreted or applied by a governmental, prosecutorial, regulatory or judicial authority in an adverse manner, it may result in monetary fines, criminal and civil penalties, settlements, suspension or exclusion from participation in Medicare, Medicaid and other federal or state healthcare programs, and/or a commitment to agree to additional regulatory oversight. For example, the Company recently entered into a Corporate Integrity Agreement with HHS. For further details, see Note 18 to the audited consolidated financial statements. |

| FDA | The FDA has regulatory responsibility over, among other areas, instruments, software, test systems, collection kits, reagents and other devices used by clinical laboratories to perform diagnostic testing in the United States. The FDA also regulates drugs-of-abuse testing for employers and insurers, testing for blood bank purposes and testing of donors of human cells for purposes such as in vitro fertilization. We offer companion and complementary diagnostic tests to pharmaceutical companies that are regulated by the FDA. In May 2024, the FDA announced it was phasing out its general enforcement discretion approach so that LDTs manufactured by a laboratory would generally fall under the same enforcement approach as medical devices. However, in March 2025, a U.S. District Court set aside and vacated the FDA’s LDT rule and the FDA did not appeal the court’s decision. Accordingly, the FDA does not have the authority to regulate LDTs. Although the FDA LDT rule was vacated in 2025, our commitment to maintaining rigorous quality standards, supporting responsible innovation, and ensuring that patient care is optimized has not changed as federal oversight evolves. In response to this evolving regulatory landscape, we continue to adapt our quality and regulatory strategies and have accelerated technology and process modernization to support greater transparency, traceability and auditability. |
| Environmental, Health and Safety | We are subject to laws and regulations related to the protection of the environment, the health and safety of employees and the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials. For example, the U.S. Occupational Safety and Health Administration has established extensive requirements relating specifically to workplace safety for healthcare employers in the United States This includes requirements to develop and implement multi-faceted programs to protect workers from exposure to blood-borne pathogens, including preventing or minimizing any exposure through needle stick injuries. For purposes of transportation, some biological materials and laboratory supplies are classified as hazardous materials and are subject to regulation by one or more of the following agencies: the U.S. Department of Transportation, the U.S. Public Health Service, the U.S. Postal Service and the International Air Transport Association. |
| Physicians | Our pathologists are required to hold a valid license to practice medicine in the jurisdiction in which they practice. The manner in which licensed physicians can be organized to perform medical services may be governed by the laws of the jurisdictions in which medical services are provided and by the medical boards or other entities authorized by these jurisdictions to oversee the practice of medicine. Several jurisdictions in which our businesses are located prohibit business corporations from engaging in the practice of medicine. In these jurisdictions, anatomic pathology services are delivered through physician-owned entities that employ the practicing pathologists. |
| Privacy and Security of Health and Personal Information | We are subject to laws and regulations regarding protecting the security and privacy of certain healthcare and personal information, including, but not limited to: (a) the federal Health Insurance Portability and Accountability Act and the regulations thereunder, which establish (i) a complex regulatory framework including requirements for safeguarding protected health information and (ii) comprehensive federal standards regarding the uses and disclosures of protected health information; (b) state laws (e.g., California) and similar laws in other states; and (c) laws outside the United States, including the European Union's General Data Protection Regulation, Canada’s Personal Information Protection and Electronic Documents Act and provincial health privacy laws, and similar laws in other jurisdictions. We may be subject to penalties for non-compliance and may be required to notify individuals or state, federal or county governments, or other data protection regulatory authorities, if we discover certain breaches of personal information or protected health information. |
|---|---|
| Drug Testing; Controlled Substances | All U.S. laboratories that perform drug testing for certain public sector employees and employees of certain federally regulated businesses are required to be certified as meeting the detailed performance and quality standards of the Substance Abuse and Mental Health Services Administration. To obtain access to controlled substances used to perform drugs-of-abuse testing in the United States, laboratories must be licensed by the Drug Enforcement Administration. |
Compliance. We strive to conduct our business in compliance with all applicable laws and regulations. We license and maintain appropriate accreditations for all of our laboratories and, where applicable, patient service centers, as required by federal and state agencies. We have a long-standing and well-established compliance program. The Quality and Compliance Committee of our Board of Directors oversees, and receives periodic management reports regarding, our compliance program. Our program includes detailed policies and procedures and training programs intended to ensure the implementation and observance of all applicable laws and regulations (including regarding billing and reimbursement, and privacy of protected health information and personally identifiable information) and Company policies. Further, we conduct in-depth reviews of procedures and facilities to assure regulatory compliance throughout our operations. We conduct annual training of our employees on these compliance policies and procedures.
As an integral part of our billing compliance program, we investigate reported or suspected failures to comply with Medicare or Medicaid reimbursement requirements. As a result of these efforts, we have periodically identified and reported overpayments, refunded the payers for overpayments and taken appropriate corrective action.
