1. Understanding Health Insurance in the USA

Health insurance in the United States is a contract between you and a private insurance company or a government program. For a monthly premium, the insurer pays a share of your qualified medical expenses.

• Why is health insurance necessary?
  U.S. healthcare is expensive: a single ER visit can cost thousands of dollars. Insurance protects you from catastrophic bills.

• Who needs it?
  All international students (F-1, J-1), most expats, and visitors are required by schools, employers, or the government to have health insurance.

• How does it work?
  You pay a premium; the insurance pays for part of your care. You may still have “out-of-pocket” costs.

For a government overview, see HealthCare.gov: How Health Insurance Works.

2. Types of Health Insurance for International Students and Expats

• School-Sponsored Plans:
  Most U.S. universities offer health insurance for international students. Coverage is often required and billed with tuition.

• Employer-Sponsored Plans:
  Expats working in the U.S. may get coverage through their employer.

• Marketplace Insurance:
  Expats with eligible visas may purchase plans on HealthCare.gov.

• Private/International Plans:
  Purchased from insurance companies specializing in international student/expat insurance (e.g., ISO, IMG, Aetna).

• Government Programs:
  Limited eligibility for Medicaid/Medicare (usually not available for non-immigrant visa holders).

Tip: Always compare coverage, deductibles, and provider networks before enrolling.

3. Key Insurance Terms Explained

• Premium: The monthly amount you pay for insurance.
• Deductible: The amount you pay out-of-pocket before your insurance starts to pay.
• Copay: A fixed amount you pay for services (e.g., $30 per doctor visit).
• Coinsurance: The percentage you pay after meeting your deductible (e.g., 20% of costs).
• Out-of-pocket maximum: The most you’ll pay in a year before insurance covers 100%.
• In-network vs. out-of-network:
  In-network providers have agreements with your insurer, leading to lower costs.

For official definitions, see Glossary of Health Coverage and Medical Terms (CMS).

4. Step-by-Step: Using Your Health Insurance to Pay Medical Bills

Step 1: Get Your Insurance Card

• Always carry your insurance card (physical or digital). It contains your member ID and group number.

Step 2: Choose an In-Network Provider

• Find doctors or hospitals that accept your insurance (see section 5).

Step 3: Make an Appointment

• Provide your insurance information when scheduling.

Step 4: Show Your Insurance Card at the Visit

• The provider will bill your insurance directly for most services.

Step 5: Understand Your Bill

• You may receive:
• Explanation of Benefits (EOB): Statement from your insurer, not a bill.
• Provider Bill: Your share after insurance pays its part (copay, deductible, or coinsurance).

Step 6: Pay Your Portion

• Pay any copay or balance due to the provider.

Step 7: Keep Records

• Save your EOBs, bills, and receipts.

5. How to Find In-Network Providers

• Check Your Insurer’s Website:
  Most have a “Find a Doctor” tool.
• Ask Your University or Employer:
  They often have lists of preferred providers.
• Call Provider Offices:
  Always ask if they accept your insurance plan before your visit.

If you see an out-of-network provider, your costs may be much higher or not covered at all.

6. How to File an Insurance Claim

• In-network providers usually file claims for you.
• Out-of-network providers may require you to file your own claim.
• Steps to file:
• Obtain a claim form from your insurer’s website.
• Attach all bills, receipts, and supporting documents (like medical certificates).
• Submit by mail or online (as required).

Tip: Keep copies of everything for your records.

8. Common Problems (and Solutions) When Using Health Insurance

Claim Denied

• Why? Incorrect billing, out-of-network care, missing documentation, or non-covered services.
• Solution: Call your insurance company, clarify the denial, and resubmit with correct paperwork.

Surprise Medical Bills

• Why? Out-of-network providers or “balance billing.”
• Solution: Always confirm network status before care and ask for an itemized bill.

Pre-Authorization Required

• Some services (surgeries, MRIs, mental health) require insurance approval before treatment.
• Solution: Ask your doctor and insurer if pre-authorization is needed.

Need for Medical Certificates

• Schools, insurers, or employers may require a doctor’s note for absence, leave, or claim approval.
• Solution: See section 9 for details.

9. Supporting Documentation: Medical Certificates and More

When do you need medical documentation?
- To justify absences from school or work
- For health insurance claims (especially for international plans)
- For leave applications (FMLA, PFL, sick leave)

What should a medical certificate include?
- Your name, date of birth, and diagnosis or treatment
- Dates of illness, injury, or care
- Provider’s name, credentials, and contact details

Who can issue it?
- Licensed U.S. healthcare providers or reputable telehealth services
