Maryland's AI rules in health care cover insurers and utilization reviewers, but its privacy law can reach practices.
Full overviewHide full overview
HB 820, in force since Oct. 1, 2025, bars an AI or software tool used in utilization review from denying, delaying or modifying care. The tool must rely on the patient's clinical history, not solely group data, and may not replace the provider's role. Bulletin 24-11, issued April 22, 2024, expects insurers and health plans to keep a written AI program. The Maryland Online Data Privacy Act, in force since Oct. 1, 2025, exempts protected health information, not practices, so a practice meeting its thresholds is covered for other personal data. HB 883, which would bar AI developers from representing that their AI provides behavioral health care, passed the House 110-23 on March 23, 2026; no Senate vote is recorded after a hearing set for April 1, 2026.
