Final answer:
BlueCross BlueShield is a) a managed care organization that is part of an association of private companies providing health insurance, not funded by government but through private means.
Step-by-step explanation:
BlueCross BlueShield is an association of private companies that provide health insurance. It is a) a managed care organization, which means it offers a variety of insurance plans and services to its members. BlueCross BlueShield is not a nonprofit health organization, a private hospital, or a governmental agency like Health and Social Services. It operates under state and federal regulations but is funded through premiums, services, and other private financial arrangements, not directly by the federal or state governments.
In the United States, healthcare coverage is divided into public healthcare, which is government-funded, and private healthcare, which includes organizations like BlueCross BlueShield. Medicare is the public healthcare system offering insurance primarily to people over sixty-five years old, and Medicaid provides medical insurance for certain low-income people. The goal of health insurance exchanges mandated by state or federal provisions is to improve competition in the market for health insurance, with companies like BlueCross BlueShield participating in these exchanges.
