1. Overview of Health Insurance in the U.S.

Health insurance is a contract that requires an insurer to pay some or all of a person's healthcare costs in exchange for a premium. In the U.S., health insurance plays a crucial role due to the high cost of healthcare services.

• Approximately 91% of Americans have some form of health insurance (as of recent estimates).

• Insurance coverage is divided between private plans and government-funded programs.

• The U.S. spends more per capita on healthcare than any other country, making insurance essential for access to care.

Health insurance in the U.S. began in the early 20th century but became widespread during World War II when employer-sponsored insurance emerged due to wage controls. Key milestones include:

• 1965: Introduction of Medicare and Medicaid.

• 2010: Passage of the Affordable Care Act (ACA), also known as "Obamacare."

• 2020–2023: Expansion of subsidies and Medicaid under pandemic-related provisions.

4. Health Insurance Terms You Should Know

Understanding health insurance requires familiarity with key terms:

• Premium: Monthly cost of the insurance plan.

5. The Affordable Care Act (ACA)

Passed in 2010, the ACA aimed to increase insurance coverage and reduce healthcare costs. Key provisions include:

6. Challenges in the U.S. Health Insurance System

Despite high insurance coverage, the U.S. system faces several challenges:

• Many Americans struggle to understand their benefits.

C. Uneven Access

• Coverage quality varies by employer, state, and income level.

D. Underinsurance

• Many insured individuals are considered underinsured—they have coverage but cannot afford to use it due to high deductibles and copays.

E. Administrative Burden

• A significant share of healthcare spending in the U.S. goes to billing, paperwork, and insurance-related administration.
