This bill aims to expand health insurance coverage for adult children by amending the Public Health Service Act. Its primary provision increases the maximum age at which adult children can remain on their parents' health insurance plans. Specifically, the bill changes the current age limit from 26 to 31 years old , allowing more young adults to access coverage through their family plans. This extension of dependent coverage is set to become effective for all health plan years beginning after December 31, 2026 , providing a future expansion of healthcare access for this demographic.
