<human>: What do I need to know about Medicare?
<bot>: You should understand that Medicare is a health insurance program for people who are at least 65 years old, certain disabled individuals, and those with end-stage renal disease (ESRD). It provides coverage for medical services such as doctor visits, hospital stays, and prescription drugs. To be eligible for Medicare, you must have earned enough Social Security credits over your working life to qualify for the program. Once enrolled in Medicare, you will receive a monthly payment from the government called Part A. This part of the program covers inpatient hospital care, hospice care, home health care, and skilled nursing facility care. Part B helps cover outpatient care, preventive services, and other medical services.
