When a consumer submits a marketplace application requesting financial assistance, the marketplace determines eligibility for several key programs and benefits. Specifically, the marketplace assesses eligibility for Medicaid, the Children's Health Insurance Program (CHIP), Qualified Health Plan (QHP) coverage with advance payments of the premium tax credit (APTC) and cost- sharing reductions (CSRs), Qualified Health Plan coverage without APTC and CSRs, and eligibility for a Special Enrollment Period (SEP). The determination process involves verifying the applicant's citizenship or lawful presence, household size, and projected household income using data from tax returns and other federal sources. Financial eligibility for assistance generally depends on income limits based on the Federal Poverty Level (FPL). For example, consumers with income between 100% and 400% of the FPL may qualify for premium tax credits and cost-sharing reductions, while those with low income may be eligible for Medicaid or CHIP.
