This paper provides an overview of health care financing in the United States, focusing on the structures that shape how individuals access and pay for medical services. It identifies and describes the three main types of health insurance — HMOs, PPOs, and CDHPs — along with three methods for categorizing coverage: indemnity, major medical, and disability. The paper then examines the three types of managed care plans, weighing their pros and cons for providers, insurers, and patients. Finally, it considers how managed care affects Medicare and Medicaid programs, noting both the cost-reduction benefits and the coverage gaps these arrangements can produce.
Over the last several years, the role of insurance companies in providing different health care solutions has been increasingly brought to the forefront. This is because costs have been rising dramatically and the total number of uninsured Americans is increasing. The combination of these factors has raised concerns that many consumers are being priced out of the system entirely.
To fully understand what is happening requires carefully examining how the industry operates. This paper looks at the three main types of insurance, the various coverage categories, the types of managed care plans, and the impact of managed care on Medicare and Medicaid. Together, these elements offer specific insights into the underlying strengths and weaknesses of the U.S. health care system.
The three main kinds of health insurance are health maintenance organizations (HMOs), preferred provider organizations (PPOs), and consumer-directed health plans (CDHPs).
An HMO provides patients with access to a network of doctors. The individual enrolls with a primary care physician, and if specialist services or tests are required, the patient must receive a referral from that primary care physician before proceeding.
A PPO gives patients a choice of primary care doctors and specialists within the plan's network, offering more flexibility than an HMO without necessarily requiring referrals.
CDHPs are designed to provide individuals with even broader choices of doctors within the insurer's network. Because the enrollee contributes a set amount of funds on a yearly basis — intended to help pay for anticipated services in advance — they gain greater flexibility in selecting doctors and hospitals ("Types of Health Insurance," 2012).
Health insurance in the United States can also be understood through three broad coverage categories: indemnity, major medical, and disability.
Indemnity coverage allows policyholders to choose their own doctors and health care providers, with the insurer reimbursing out-of-pocket expenses above specified thresholds over select periods of time.
"Pros and cons for patients, providers, insurers"
"Cost reductions and coverage gaps in public programs"
The combination of rising costs and a growing uninsured population highlights the structural tensions within U.S. health care financing. Understanding how insurance types, coverage categories, and managed care plans interact is essential to evaluating where the system succeeds and where gaps remain. HMOs, PPOs, CDHPs, and POS plans each represent a different balance between cost control and patient choice, while the extension of managed care into Medicare and Medicaid illustrates both the promise and the limitations of market-based approaches to public health coverage.
