Healthcare Mechanisms from Policy-as-Code Search under Strategic Provider Response

In three linesResearchers reframe healthcare mechanism design as program synthesis for LLMs. Medi-Sim, a multi-agent simulator, evaluates rule programs against strategic provider responses (coding, selection, delay, effort, triage). LLM-guided evolutionary code search synthesizes a mixed-objective program that eliminates up-coding, halves rejections, and retains baseline profitability.
