If you don't have any experience working in a doctor's office, consider your connections. Your resume may only take you so far, so network to see if you can get your foot in the door by who you know. Start with your immediate friends and family and ask if they know anyone who works in a medical office.
What's Medicare? Medicare is the federal health insurance program for people who are 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease (permanent kidney failure requiring dialysis or a transplant, sometimes called ESRD).
In general, all persons 65 years of age or older who have been legal residents of the United States for at least five years are eligible for Medicare. People with disabilities under 65 may also be eligible if they receive Social Security Disability Insurance (SSDI) benefits.
