Health insurance in USA

Health insurance in the USA is a complex system involving private and public options. Here’s an overview:  

1. Types of Health Insurance

A. Private Health Insurance
Employer-Sponsored Insurance (ESI)

 Most Americans get coverage through their employers. Employers typically share the premium costs with employees.  
Individual Market Plans

 People can buy insurance directly through the **Health Insurance Marketplace (Obamacare)** or private insurers.  
Short-Term Plans

 Temporary, limited-coverage plans for those in between jobs or waiting for long-term coverage.  

B. Public Health Insurance
Medicare – Federal program for individuals **65+** and some younger people with disabilities.  
Medicaid – Joint federal-state program for **low-income individuals and families**.  
CHIP (Children’s Health Insurance Program)** – Covers low-income children whose families don’t qualify for Medicaid.  
VA (Veterans Affairs) & TRICARE** – Insurance for veterans and military personnel.  

2. Health Insurance Marketplace (Obamacare)
- Created by the **Affordable Care Act (ACA)** in 2010.  
- Allows people to compare and buy plans with **subsidies** based on income.  
- Covers **pre-existing conditions** and essential health benefits.  
- Open Enrollment usually runs from **November to January** (with special enrollment periods for qualifying life events).  

3. Key Terms to Understand

- **Uninsured Population** – Millions remain uninsured due to affordability or lack of awareness.  
- **Employer Dependence** – Many rely on jobs for insurance, leading to gaps when unemployed.  
- **State Variations** – Medicaid eligibility and rules differ by state.  

5. How to Get Health Insurance
