policyengine-healthcare

US healthcare domain knowledge (Medicaid, ACA premium tax credit, CHIP, Medicare) for analysts using the policyengine package. Load for: why ACA PTC and Medicaid changes show $0 in household_net_income (the include_health_benefits_in_net_income gotcha) and how to measure health impact instead; the aca_ptc / medicaid / medicaid_category / slcsp / is_aca_ptc_eligible / per_capita_chip variables; Medicaid category precedence (42 CFR 435.119); the _fc/_nfc split; why a flat reform dict fails on required_contribution_percentage; slcsp returning $0 for the ineligible; and what "IRA reform" means. Triggers: Medicaid, ACA, premium tax credit, PTC, aca_ptc, SLCSP, CHIP, Medicare, MAGI, coverage gap, Medicaid expansion, IRA subsidy extension, required contribution percentage, age curve, family tier, medicaid_category. NOT for: non-health US programs (use policyengine-us); new health variables (use policyengine-model-development); core calculate_household / Simulation mechanics (use the policyengine skill).
