Financing the Program
20.1 - Financing the Program
(Rev. 1, 09-11-02)
Part A is financed through separate payroll contributions paid by employees, employers, and
self-employed persons. The proceeds are deposited to the account of the Federal Hospital
Insurance Trust Fund, which is used only for hospital insurance benefits and administrative
expenses. Federal employees and State and local employees who do not pay the full FICA tax
must pay the HI portion; they are not eligible for monthly Social Security or railroad retirement
benefits. The cost of providing Part A benefits to other persons who are not Social Security or
railroad retirement beneficiaries is met by appropriations to the Federal Hospital Insurance Trust
Fund from general revenues or through premium payments.
Part B is financed by monthly premiums of those who voluntarily enroll in the program and by
the Federal Government which makes contributions from general revenues. All premiums and
Government contributions are deposited in a separate account known as the Federal
Supplementary Medical Trust Fund. Money from this fund is used only to pay for Part B
benefits and administrative expenses.
