Health care law encompasses the laws and regulations governing hospital and health care administration, and an understanding of health care insurance is integral to it. There are significant differences in the types and amount of coverage provided by various private insurance policies, such as HMOs, PPOs, disability insurance, and hospital indemnity insurance, just as there are important differences in the cost to the purchasers of health insurance. There are also public health care insurance programs. Elderly and disabled persons may be eligible for coverage through the federal Medicare program. The joint state-federal Medicaid program helps certain individuals, including disabled persons and low-income elderly persons, pay for long-term care and in-home health care.
Ringwood is a village in McHenry County, Illinois, United States. The Ringwood post office was established in the early 1900s to provide post office boxes for local industrial firms and residents located on the far northern edge of McHenry. In the late 1980s, Johnsburg, which has no post office, annexed major portions of unincorporated McHenry County. Ringwood was incorporated as a village on 15 November 1994 in an attempt to maintain its small-town environment. The population was 471 at the 2000 census.
