eligibility; children's health insurance program

HB 2460 amends Arizona's children's health insurance program (CHIP) eligibility rules by adjusting income thresholds for children under 19. It sets the following income limits relative to the federal poverty level: 200% for 1999-2023, 225% (with CMS approval) for 2023-2025, and 300% starting October 1, 2025. The bill directly affects low-income Arizona families with children under 19 whose household income meets these revised thresholds. It does not change program benefits or structure, only the income eligibility percentages. The amendment is part of defining program terms in Arizona Revised Statutes Section 36-2981.
