Health plans are agreements between individuals and insurance companies that provide financial coverage for medical expenses. These plans can vary widely in terms of cost, coverage, and the types of services included, such as doctor visits, hospital stays, and prescription medications. Common types of health plans include Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and Exclusive Provider Organizations (EPOs). Individuals typically pay a monthly premium for their health plan, along with additional costs like deductibles and copayments when they receive care. Health plans are essential for managing healthcare costs and ensuring access to necessary medical services, helping to protect individuals from high out-of-pocket expenses.
