Which of the following best defines a Health Maintenance Organization (HMO)?

The correct choice defines a Health Maintenance Organization (HMO) as a company offering health care services for a fixed prepaid premium. This model emphasizes preventive care and focuses on maintaining the overall health of its members rather than just treating illnesses as they arise. Members typically pay a monthly premium, which covers a range of health services, and they are encouraged to use a network of designated providers.

The HMO structure generally requires members to choose a primary care physician (PCP) who acts as a gatekeeper for accessing specialized services. This system helps control costs and ensures that patients receive comprehensive care tailored to their health needs. The prepaid model allows for predictable pricing for patients and promotes efficient use of healthcare resources, aligning financial incentives with patient wellness.

Other definitions, such as those related to flexible coverage options, tax benefits for medical expenses, or a general group of healthcare providers, do not capture the essence of how an HMO operates within the healthcare system, focusing instead on specific aspects rather than the overall service model.
