How do I shop for health insurance?

Shop for health insurance by comparing plans on total cost (premium plus your expected out-of-pocket), verifying your doctors and prescriptions are covered in-network, and understanding the difference between HMO, PPO, and HDHP plan types. The federal marketplace at HealthCare.gov is the starting point for individual and family coverage if you don't have employer-sponsored insurance.

Health insurance is often the most complex consumer insurance purchase because it involves four interacting cost variables — premium, deductible, copay, and coinsurance — plus network restrictions that determine which providers you can use. The HealthCare.gov plan comparison tool is the federal government's free resource for individual and family marketplace shopping; state-run exchanges serve the same function in states that have their own marketplaces.

Understand your total annual cost, not just the premium

A low premium often means a high deductible and higher cost-sharing when you actually use care. The right comparison is total expected annual cost: monthly premium × 12, plus your estimated out-of-pocket spending under each plan (using your realistic utilization). HealthCare.gov's plan comparison guide walks through this framework. The out-of-pocket maximum sets a ceiling — once you hit it, the plan pays 100% of covered in-network costs for the rest of the year.

HMO vs. PPO vs. HDHP — what the plan type means

HMO (Health Maintenance Organization): lower premiums, but you need a primary care physician (PCP) referral to see specialists and must stay in-network for non-emergency care.
PPO (Preferred Provider Organization): more flexibility to see out-of-network providers and specialists without a referral, at higher premiums.
HDHP (High-Deductible Health Plan): higher deductible, lower premium, and — critically — eligibility to open a Health Savings Account (HSA). Contributions to an HSA are tax-deductible.
EPO (Exclusive Provider Organization): no out-of-network coverage except emergencies; no referral required within network.

Check the network before you enroll

Before enrolling, verify that your current primary care physician, specialists, and any preferred hospital are in the plan's network. Out-of-network costs can be significant, and HMO and EPO plans provide no out-of-network coverage outside emergencies. The HealthCare.gov glossary defines network, in-network, and out-of-network precisely.

When you can enroll — and what to do outside open enrollment

Individual marketplace plans have an annual open enrollment period (typically November 1 – January 15 for plans starting the following January). Outside that window, you can only enroll if you experience a qualifying life event — job loss, marriage, birth of a child — which triggers a Special Enrollment Period (SEP). HealthCare.gov's enrollment guide describes qualifying events. Employer-sponsored plans follow their own enrollment schedules.
