Medicare Part B is basically medical insurance, meant to help with doctors bills in and out of the hospital, as well as other expenses you might incur while you are not in the hospital. Whether you are eligible for Part A or not, you can still be eligible for Part B Medicare, so long as you’ve lived legally in the United States for five consecutive years. The costs for Part B Medicaid is $66.40 per month. Medicare Part B helps cover your doctors’ services, outpatient hospital care, and some other medical services that Medicare Part A doesn’t cover, such as some of the services of physical and occupational therapists, and some home health care. Most people who choose to enroll in Medicare Part B do not get a premium billing notice because their premiums are deducted from their monthly social security.
