Marketplace eligibility and enrollment

Domain 2 tests who is eligible for Marketplace coverage and financial assistance, and when a consumer may enroll. Expect questions on advance premium tax credits (APTC), cost-sharing reductions (CSR), open enrollment, special enrollment periods (SEPs), and verification.

Eligibility and financial assistance

  • Marketplace eligibility requires U.S. citizenship or nationality, or lawful presence; residence in the service area; and not being incarcerated. Incarcerated people may enroll in a QHP but cannot receive APTC or CSR while incarcerated.
  • APTC requires a tax household that files a return, meets income rules, and lacks access to affordable minimum essential coverage (MEC). Employer coverage is generally unaffordable if the employee's required contribution for self-only coverage exceeds the applicable percentage of household income; the family glitch fix also considers family coverage affordability.
  • APTC is computed from the second-lowest-cost Silver benchmark. It can be applied to any metal level, but CSR is only on Silver plans.
  • CSR is available at 100-250% FPL and has three tiers at 94%, 87%, and 73% actuarial value. Above 250% FPL, no CSR.
  • Reconcile APTC on the federal tax return using Form 1095-A and Form 8962. Married applicants generally must file jointly to receive APTC.

Enrollment windows

  • Open Enrollment runs November 1 to January 15 in the FFM. Enroll by December 15 for January 1 coverage; December 16 to January 15 for February 1.
  • SEPs require a qualifying life event and a 60-day window. Loss of MEC: 60 days before or after. Marriage: 60 days. Birth or adoption: 60 days after. Move, Medicaid or CHIP denial, and other events have specific rules.
  • Applications undergo data matching; inconsistencies trigger a document request, typically a 90-day period. Coverage is not final until the first premium is paid.

Worked example

A single adult projects 300% FPL, has no employer coverage, and is not Medicaid-eligible. She qualifies for APTC but not CSR because 300% FPL exceeds 250%. If she chooses Bronze, she keeps APTC but gets no CSR; if she chooses Silver, she still gets no CSR at 300%. A common wrong answer says Silver always means CSR. It does not.

Traps

  • Assuming incarceration bars enrollment; it bars APTC and CSR.
  • Missing the 60-day SEP deadline or using the event date incorrectly.
  • Confusing Medicaid or CHIP eligibility with Marketplace eligibility.
  • Forgetting APTC reconciliation and joint-filing rules.
