How US Healthcare Works
The US does not have a universal healthcare system. Instead, coverage comes through a patchwork of employer-sponsored insurance (covering ~155 million Americans), government programs (Medicare for 65+, Medicaid for low-income), and individual marketplace plans under the Affordable Care Act (ACA). As an expat, your employer will likely provide health insurance as part of your compensation package — this is the standard and most cost-effective option.
- Employer-sponsored insurance: covers 155+ million Americans; typically the best coverage available
- ACA Marketplace (Healthcare.gov): individual plans available during Open Enrollment (November–January)
- Medicare: federal health insurance for those 65+ or with certain disabilities
- Medicaid: state-run health coverage for low-income residents; eligibility varies by state
- CHIP: Children's Health Insurance Program for children in families that earn too much for Medicaid
- Uninsured: approximately 26 million Americans lack health insurance
- Emergency rooms must treat all patients regardless of insurance status (EMTALA law)
