Avoid a coverage gap

Build a dated enrollment record

  1. Identify the route. Use the Marketplace, employer, Medicaid/CHIP, or Medicare system that governs the coverage.
  2. Record the triggering date. For a possible Special Enrollment Period, save the event and prior-coverage dates exactly.
  3. Read the official notice. It controls eligibility, requested evidence, and next actions.
  4. Compare live plans. Check coverage start dates, providers, drugs, total cost, and plan documents.
  5. Complete payment steps. Plan selection and premium payment can be separate; follow the official instructions.
  6. Confirm activation. Keep confirmation from the Marketplace and insurer before assuming coverage is active.

COBRA and Marketplace timing can interact

COBRA can continue certain job-based coverage after qualifying events, often with the individual paying more of the premium. A Marketplace Special Enrollment Period may also be available after losing job-based coverage. Choosing, ending, or exhausting COBRA can affect timing, so compare official notices, plan costs, provider continuity, and deadlines before acting.
