Voluntary Program for Medicare Part B Coverage

A

The correct answer is A. Supplementary medical insurance.

Supplementary Medical Insurance (SMI) is a voluntary program under Medicare that provides payments for services not covered under basic hospital insurance. It is commonly referred to as Medicare Part B.

Medicare is a federal health insurance program primarily for people who are 65 or older, but also for some younger people with certain disabilities or health conditions. Medicare has four parts: A, B, C, and D.

Part A provides coverage for inpatient hospital care, skilled nursing facility care, hospice care, and home health care. Part B provides coverage for doctor visits, outpatient services, preventive care, and medical equipment. Part C, also known as Medicare Advantage, allows beneficiaries to receive Part A and B benefits through a private insurance plan. Part D provides coverage for prescription drugs.

Supplementary Medical Insurance (Part B) is optional and requires payment of a monthly premium. It covers medically necessary services and supplies that are not covered by Part A, such as doctor visits, outpatient care, and preventive services.

National health care and Blue Cross are not Medicare programs. National health care refers to a government-funded healthcare system that provides healthcare for all citizens, while Blue Cross is a private health insurance company.
