Regulates the use of AI, algorithms, and software tools in utilization review and medical necessity determinations by utilization review agents (under Public Health Law) and disability insurers including specialized health insurers (under Insurance Law). Prohibits AI tools from serving as the basis for denying, delaying, or modifying healthcare services based on medical necessity — such determinations must be made by a licensed physician or competent healthcare professional reviewing individualized clinical data. Requires that AI tools base determinations on individual enrollee clinical history rather than solely on group datasets, prohibits discrimination, mandates periodic performance review, restricts patient data use consistent with HIPAA, and requires AI tools to be open to regulatory inspection. Enforced by the Department of Health and the Department of Financial Services through existing regulatory authority.
