Medicare is a social security coverage program administered by the United States government, which provides medical care to all people over 65 years of age or younger who are considered disabled due to serious health problems, such as cancer, kidney failure in need of dialysis, etc. The program also funds the training programs of resident physicians in the United States. Medicare operates as a person insurance.

Medicaid is a health insurance program of the United States Government for people in need. Each state has a Medicaid program that provides health coverage for people with low incomes, families and children, the elderly and people with disabilities. Most states provide coverage for adults with children who are at a certain low level of income. In addition, beginning in 2014, most adults under the age of 65 with individual incomes of up to approximately $ 15,000 per year are eligible for Medicaid in all states.
