CMS Asks the Public to Help Rewrite Rules for Medical Labs, Including How AI Reads Test Results

CMS and the Centers for Disease Control and Prevention published a request for information on July 16, 2026, inviting labs, patients, and other stakeholders to weigh in on potential updates to the Clinical Laboratory Improvement Amendments of 1988, known as CLIA. Those regulations have set federal quality standards for clinical laboratories since taking effect in 1992, but the agencies say technological change has outpaced the existing framework. The request covers a wide range of topics including laboratory processes, emergency preparedness, biosafety, and cybersecurity. A particular focus is artificial intelligence. CMS is asking how algorithms should be used in post-analytical lab workflows, how labs should verify the performance of AI tools that interpret results from fields such as next-generation gene sequencing and pharmacogenomics, and what oversight, if any, should apply to AI-assisted reading of pathology slides. The agencies are also seeking input on so-called data-only facilities, which produce clinical recommendations from data rather than physical specimens, and how those should be regulated. Comments are due September 14, 2026. CMS says the request does not commit the agency to any specific rulemaking but will help inform what updates, if any, to pursue. Because Medicare pays for a wide range of lab services under its Clinical Laboratory Fee Schedule, any new standards that eventually take shape could affect how test results are produced and reviewed for millions of beneficiaries.
