About this list
The list comes from the network files insurers publish for their HealthCare.gov Marketplace plans for 2027, matched to hospitals by their provider numbers (NPIs). A hospital that isn't listed may still be in network under a provider number we haven't matched.
It covers Marketplace (ACA) plans in the states that use HealthCare.gov, not job-based insurance, Medicare or Medicaid. Distances are straight-line from the center of your ZIP code. Star ratings are CMS's overall hospital ratings.
In an emergency, call 911 or go to the nearest ER: Marketplace plans must cover emergency care at any hospital without prior approval.
