MCPR 2001 - Measuring the Quality of Pennsylvania's Commercial HMOs - What is an HMO?


Most Pennsylvanians receive their health care benefits through their employer or from a government-sponsored program such as Medicare or Medical Assistance. An HMO is an organized system that provides prepaid health benefits to a defined group of members.

Unlike traditional insurers, HMOs typically offer and encourage members to take advantage of a host of educational materials, disease management programs, preventive health services and other initiatives to keep their members healthy. HMO members usually are required to select a Primary Care Physician (PCP) who has the responsibility to coordinate the various health services available to members.

HMOs may share financial responsibility with PCPs and other providers for the services provided to members. "Point-of-Service" (POS) options offered by HMOs often combine the structure of HMOs (members select PCPs and usually access non-primary care services through pre-approved referrals) with the flexibility to access services without pre-approved referrals and the option to leave the network of participating providers by paying an additional fee.

A summary of the characteristics of the types of health insurance plans is provided in the table below.
