To amend the Patient Protection and Affordable Care Act to identify individuals dually enrolled in Medicaid or CHIP and an Exchange.

This bill requires the federal government to automatically identify people enrolled in both Medicaid/CHIP (free or low-cost public coverage) and a private health plan purchased through a health insurance marketplace (Exchange). It mandates quarterly data matching between Exchange enrollment records and Medicaid/CHIP records using the Public Assistance Reporting System (PARIS) within 60 days of enactment. If an individual is found enrolled in both programs, the government must stop providing them with premium tax credits or cost-sharing subsidies through the Exchange. The policy directly affects dual enrollees who would otherwise receive duplicate government health coverage subsidies.
