United States Healthcare System Guide
How the healthcare system works in United States — emergency numbers, GP access, vaccines, insurance and medical costs for visitors and expats.
Healthcare system overview
The United States has no universal healthcare system. Healthcare is primarily delivered through private providers and funded by private insurance, with government programmes (Medicare for over-65s, Medicaid for low-income) covering specific groups. Visitors have zero public coverage and must rely entirely on travel insurance or pay out-of-pocket. Costs are among the highest in the world — a simple ER visit can cost $3,000-5,000+, and medical debt is the #1 cause of personal bankruptcy. Urgent care centres are a cost-effective alternative to ERs for non-life-threatening issues.
System type: Private insurance-based. No universal coverage.
Emergency numbers & response
Dial: 911
Typical response time: 7-10 minutes urban, 15-30+ minutes rural. EMS response times vary dramatically by region.
Costs: ER visit: $1,500-5,000+ (before any treatment). Ambulance: $400-1,200+ (ground), $20,000-50,000+ (air ambulance). Hospital stay: $2,000-5,000+/day. ICU: $10,000+/day.
Call 911 for all emergencies. Under EMTALA law, ERs MUST stabilise all patients regardless of insurance or ability to pay — but you WILL receive a bill. For non-life-threatening issues, urgent care centres ($100-300) are vastly cheaper than ERs. Many hospitals now offer online ER wait time estimates.
Seeing a doctor as a visitor
By appointment with PCP (primary care physician). Urgent care centres for walk-in non-emergency. Telehealth (Teladoc, MDLive, Amwell) widely available for virtual visits. MinuteClinics in CVS/Walgreens for basic care.
Typical wait: PCP appointment: 1-3 weeks advance booking. Urgent care: 15-45 min wait. Telehealth: same-day/immediate. MinuteClinic: 15-30 min wait.
Typical cost: With insurance: $20-50 copay. Without insurance: $100-300+ (PCP), $150-500 (urgent care), $50-75 (telehealth), $99-150 (MinuteClinic). Specialists: $200-500+.
Good in metro areas. Primary care shortages in rural areas, particularly in the South and Midwest. Urgent care centres and retail clinics (CVS MinuteClinic, Walgreens) are widely accessible alternatives. Telehealth has exploded since COVID.
Vaccines for travel
Recommended: Routine vaccines (MMR, DTP, Polio, Flu), COVID-19, Hepatitis A, Hepatitis B, Measles (MMR booster — outbreaks reported)
CDC mandates all international travellers ensure measles immunity. No yellow fever or polio entry requirements for tourists. Immigrant visas require comprehensive vaccination history — missing vaccines must be administered before visa approval.
Insurance & visa health requirements
Insurance required for visa: depends
Public coverage for visitors: no
ESTA for Visa Waiver Program countries (90 days max, no extension). No universal healthcare — comprehensive travel insurance is essential. Social media disclosure required on DS-160 visa application. Background checks are thorough — previous visa refusals or overstays can affect applications.
Documents to prepare:
- Comprehensive travel/health insurance with high coverage limits ($100,000+ minimum recommended)
- Insurance card and policy details (physical and digital copies)
- Credit card with high limit (for deposits/copays — many facilities require upfront payment)

Typical medical costs
Private GP visit: $100-300+ (PCP without insurance). Urgent care: $150-500. Telehealth: $50-75. MinuteClinic: $99-150.
Emergency care without insurance: ER visit: $1,500-5,000+ before treatment. Ambulance: $400-1,200+. Hospital stay: $2,000-5,000+/day. A broken arm: $2,500-10,000+. Appendectomy: $15,000-40,000+.
