To model ACA marketplace subsidies, the Skill applies nested parameter structures under gov/aca, handles SLCSP calculations, and adjusts rating area rules within PolicyEngine-US to simulate eligibility and premium tax credit amounts.

Yes, Medicaid eligibility checks across state variations are simulated using nested parameters under gov/hhs/medicaid and applying state-level overrides to test specific jurisdictional rules and expansion scenarios within the microsimulation.

Healthcare policy microsimulation models population-level program interactions for Medicaid, ACA, CHIP, and Medicare. Take-up dynamics adjust predicted enrollment behavior, directly impacting distributional spending results by income, state, and program interaction.

Reform impact assessments for IRA subsidy extensions and Medicaid expansion are performed by modifying parameter timelines and state overrides, then running baseline microsimulations to compare distributional spending and eligibility shifts.

Yes, the modeling approach supports end-to-end simulation of Medicare and CHIP alongside Medicaid and ACA, allowing analysts to evaluate complex program interactions and spending impacts under state-specific rules and reform scenarios.
