eligibility; children's health insurance program

HB 2521 amends Arizona's children's health insurance program (CHIP) eligibility rules by adjusting income thresholds for children under 19. It increases the income limit from 200% of the federal poverty level (FPL) to 225% for fiscal years 2024-2026, then to 300% for all subsequent years. This change directly affects low-income families whose children qualify for CHIP coverage based on household income. The bill updates the legal definition of "member" in the program without altering its structure or administration.
