Marketplace Coverage

Marketplace plans are private ACA-compliant individual plans sold through HealthCare.gov or a state Marketplace. An application assesses eligibility for premium tax credits, cost-sharing reductions, Medicaid, and CHIP.

Private Coverage Outside the Marketplace

Private insurance can include ACA-compliant individual plans sold directly by insurers as well as supplemental or limited products. Income-based Marketplace savings generally require Marketplace enrollment.

Verify Before Buying

Confirm whether a product is comprehensive major medical coverage, what it excludes, how pre-existing conditions are treated, which network applies, and whether an available Marketplace subsidy was considered.

Questions to Ask Before Choosing

  1. Which option am I eligible to enroll in now?
  2. What is the net annual premium after applicable contributions or savings?
  3. Are my providers, facilities, and prescriptions covered?
  4. What would I pay under low, expected, and high use of care?
  5. Which deadlines, effective dates, and documents control?
