Medical care can generate bills that exceed most households’ ability to pay. Health insurance covers the cost of medical services, hospitalization, prescription drugs, and related care, subject to deductibles, copayments, coinsurance, and coverage limits defined in the plan.

Plans may be indemnity arrangements that reimburse a portion of charges or network-based models such as HMOs and PPOs that negotiate fees and manage care pathways. Employer-sponsored group plans, individual market policies, and government programs all provide health coverage through different structures.

Premiums reflect age, location, plan richness, and, in some markets, health status or smoking. Regulatory rules govern guaranteed issue, essential benefits, and rating factors in many jurisdictions. The design of cost-sharing and provider networks strongly influences both access to care and the financial protection the insurance provides.
