Blue Cross Blue Shield

One of the oldest and largest health insurance providers in the nation, Blue Cross and Blue Shield began in 1929 as small, privately-owned insurance companies providing health coverage to small groups of citizens. Today, the company consists of a network of 29 health insurance providers, covering over 100 million Americans.

Every state in the union has some form of Blue Cross and Blue Shield health coverage. The “company” is actually an affiliation of independent providers. Blue Cross companies handle hospitalization insurance, while Blue Shield companies provide medical coverage to pay for doctors and other expenses. In the past, all Blue Cross and Blue Shield affiliates were 501(c)(4) organizations. Today, some Blue Cross and Blue Shield providers are non-profit organizations, while some are stock companies. Most Blue Cross and Blue Shield providers operate on a managed-care basis, through an HMO or PPO structure.

Blue Cross and Blue Shield also act as administrators for Medicare in several states. It is often more cost-effective for the states to contract these services to Blue Cross or Blue Shield than to implement them. Several Blue Cross and Blue Shield affiliates are multi-state companies, such as the 14-state WellPoint, Care First in the Mid-Atlantic, and The Regence Group in the Pacific Northwest.

Assurant Health

Assurant Health is a subdivision of the larger Assurant group. Assurant Health focuses on two major areas of needed healthcare coverage: short-term policies and small group employers. By covering these two areas, Assurant Health provides a much-needed service to small business owners and those who are self-employed. Assurant Health’s premiums are intentionally kept as low as possible to meet the needs of these self-employed or small-business clients. However, in order to do this, Assurant Health must closely monitor the allocation of funds, so the company may investigate more closely than a larger insurer to be sure claims are valid and covered. The Assurant group employs approximately 14,000 people in its four subsidiaries, and realizes a net capital per year of around $279 million. Assurant received an “A-“ (excellent) in financial stability from A.M. Best.
