1. U.S. Healthcare System Structure

1.1 Private and Public Providers

The U.S. system is a mix of public and private providers:

• Hospitals: Public (government-funded) and private, often not-for-profit.
• Clinics: Community health centers, urgent care, and specialty clinics.
• Primary Care Providers (PCPs): Your first point of contact for non-emergency medical issues.
• Specialists: Doctors focusing on particular fields (e.g., cardiology, dermatology).
• Telemedicine: Growing rapidly; enables online consultations and digital documentation.

1.2 No “Universal Care”

Unlike many countries, the U.S. does not have a universal, government-funded healthcare system for all residents. Most people rely on:

• Employer-sponsored insurance
• Individual market insurance
• Public programs (Medicare for seniors, Medicaid for low-income)
• Student/visitor plans for non-citizens

2. Registration: How to Book a Medical Appointment

2.1 Finding a Provider

• Use your insurance network’s directory or popular platforms like Zocdoc.
• Search for “Primary Care Physician near me” or “Urgent Care.”
• Many providers also offer telehealth (online) appointments.

2.2 The Booking Process

• Call or book online: Many clinics require advance booking, but urgent care/walk-in clinics accept same-day visits.
• Provide ID and insurance: Have your photo ID and insurance card ready.
• Explain your need: Be clear if you need a check-up, prescription, specialist referral, or documentation.

3.3 Costs and Insurance

• ER visits are expensive (often $1000+ without insurance).
• Urgent care is much cheaper ($100-$200).
