Medicare Part A (Hospital Insurance)
Most people get Part A for free, but some have to pay a premium for this coverage.
To be eligible for premium-free Part A, an individual must be entitled to receive Medicare based on their own earnings or those of a spouse, parent, or child. To receive premium-free Part A, the worker must have a specified number of quarters of coverage (QCs) and file an application for Social Security or Railroad Retirement Board (RRB) benefits. The exact number of QCs required is dependent on whether the person is filing for Part A on the basis of age, disability, or End Stage Renal Disease (ESRD). QCs are earned through payment of payroll taxes under the Federal Insurance Contributions Act (FICA) during the person's working years. Most individuals pay the full FICA tax so the QCs they earn can be used to meet the requirements for both monthly Social Security benefits and premium-free Part A.
NOTE: Certain Federal, State, and local government employees pay only the Part A portion of the FICA tax. The QCs they earn can be used only to meet the requirements for premium-free Part A; they may not be used to meet the requirements for monthly Social Security benefits.
