Understanding Health Insurance
Health insurance is a contract between you and an insurer that requires the insurer to pay some or all of your healthcare costs in exchange for a monthly premium. Health insurance helps cover medical expenses including doctor visits, hospital stays, surgeries, prescription drugs, preventive care, and mental health services.
In the United States, most people get health insurance through their employer, through government programs (Medicare, Medicaid, CHIP), or through the individual marketplace (Healthcare.gov). Understanding your options is essential for selecting a plan that provides genuine value for your healthcare needs and budget.
HMO vs PPO vs HDHP
HMO — Health Maintenance Organization
HMO plans require you to choose a primary care physician (PCP) and get referrals to see specialists. You must use in-network providers except in emergencies. HMOs typically have lower premiums and out-of-pocket costs than PPOs but less flexibility in provider choice. Best for: budget-conscious individuals who prefer coordinated care and don't frequently need specialist access.
PPO — Preferred Provider Organization
PPO plans give you more flexibility to see any doctor without a referral, including out-of-network providers (at higher cost). You pay less when using in-network providers but still have coverage outside the network. PPOs typically have higher premiums than HMOs. Best for: individuals who want maximum provider flexibility or have established relationships with specific specialists.
HDHP — High-Deductible Health Plan
HDHPs have lower premiums but higher deductibles (minimum $1,600 individual/$3,200 family in 2025). They are paired with Health Savings Accounts (HSAs) that let you save pre-tax dollars for medical expenses. Best for: healthy individuals who rarely use medical services and want to build tax-advantaged healthcare savings.
Understanding Health Insurance Costs
- Premium: Monthly payment to maintain coverage regardless of whether you use healthcare services.
- Deductible: Amount you pay out of pocket before insurance begins covering costs. A $3,000 deductible means you pay the first $3,000 of medical costs each year.
- Copay: Fixed amount you pay for a covered service (e.g., $25 for a doctor visit) after meeting your deductible.
- Coinsurance: Percentage of costs you pay after meeting your deductible (e.g., 20% coinsurance means insurance pays 80%, you pay 20%).
- Out-of-Pocket Maximum: The most you will pay for covered services in a plan year. After reaching this limit, insurance covers 100% of covered costs.

Open Enrollment
Open enrollment for individual health insurance through the ACA marketplace typically runs from November 1 through January 15. Outside open enrollment, you can only enroll if you qualify for a Special Enrollment Period (SEP) due to a qualifying life event — losing job-based coverage, marriage, divorce, having a baby, or moving to a new area.
Employer-sponsored plans have their own open enrollment periods, typically in the fall. Medicare open enrollment runs October 15 through December 7 for Medicare Advantage and Part D plans.
