NY A 8556 prescribes requirements for the use of AI, algorithms, or other software tools in utilization review by utilization review agents (under the Public Health Law) and disability insurers including specialized health insurers (under the Insurance Law). The bill requires that AI tools used in coverage determinations base their outputs on individualized enrollee clinical data rather than solely on group datasets, prohibits AI from denying, delaying, or modifying healthcare services based on medical necessity, and requires that all medical necessity determinations be made by licensed physicians or competent healthcare professionals. The bill also mandates periodic review and revision of AI tools for accuracy, limits patient data use to stated purposes consistent with HIPAA, requires disclosures about AI use in written policies and procedures, and ensures AI tools are open to regulatory inspection. The bill applies in parallel to the Public Health Law and Insurance Law with substantially identical obligations.
