health maintenance organization - Investment & Finance Definition
An insurance company that provides a range of services and coverage for a flat monthly fee with no deductible. The HMO network requires that patients use only doctors in the HMO network. If patients use out-of-network doctors, the patient has to shoulder a greater proportion of the expense. Visits to specialists or hospitals have to be approved in advance by either the HMO staff or the insured’s primary care physician.Webster's New World Finance and Investment Dictionary Copyright © 2010 by Wiley Publishing, Inc., Indianapolis, Indiana.
