Medicare

Explanation:

Medicare is the United States National Health Insurance Program for people 65 years of age or older. Some people under the age of 65, such as people with disabilities, people with permanent renal failure, or amyotrophic lateral sclerosis (Charcot's disease), can also participate in the Medicare program. The program helps pay for medical care, but it does not cover all medical expenses and not all expenses for long-term care. The Medicare program is funded by a portion of the payroll tax levied on both employees and employers. It is also partially funded by monthly contributions deducted from Social Security benefits.

Medicare was created with the aim of working with citizens of retirement age who want to solve health problems. The program exists entirely on funds deducted from corporate income tax, progressive income tax and payroll tax. Due to its existence, hospital systems everywhere receive part of their income; up to about half of the budget of these institutions are revenues from the Medicare program.

Medicare has a slightly different line of services, due to the fact that the program serves older Americans and solves their health problems. So, most often, the program is used in order to receive some preventive services, undergo inpatient treatment, or to be able to call a doctor at home for some kind of therapeutic procedures.
