Security is the main concern for anyone buying a health insurance policy. However, financial security is not the only aspect associated with it. One requires a peace of mind with the thought that their policy is intact and incase a need arises, a claim can be applied for which would be duly surrendered by the insurance agency. At this time, the largest and the oldest companies are the best bet, even if it means paying a bit extra compared to the smaller ones, which may or may not be capable enough of doing the same.

Of the hundreds of health insurance companies, the ones that make the best can be found in the list below - they are known to offer the best health insurance and best dental health care insurance plans. They are not ranked according to their position as the number 1 spot keeps fluctuating between them from year to year.

a) United Health Group: This Company has been in business since the 1970s and one of the mature players in the field of health insurance. With a client backing of more than 70 million members, they easily are the largest insurance company in America. Talking about the number of tie ups, it has signed documents with more than 4,500 healthcare institutions. A policy from this company can be easily bought with them having branches in all states of the country.

b) CIGNA Corporation: In the market since the late 18th century, there is no company as old as the CIGNA Corp. They have individual, family, group and Medicare plans on offer for the people. With a 24x7 support for its clients, they are one of the leading agencies providing health statements and explanations of benefits.

c) Well Point: Even though it has been in the market for less than 10 years, with a 35 million registered clients count, Well Point is not a small player in the league. They have a total turnaround of over $55 billion. If their statements are to be believed, 1 in every 9 Americans is associated with them. One of their major commitments is to bring affordable and quality healthcare to the people of the country.

d) Medicare: Administered by the United States government for people of more than 65 years of age, Medicare is a huge force with the increasing average age of the American population. With disability plans and other not so common plans, it has been able to approach those sections of the society which was otherwise not considered for a health insurance plan. It has been boosted by good advertising and the backing of the central government.

e) Aetna: This health insurance company came into picture in the mid 19th century and has since only seen an upward trend. It was this agency that brought about the consumer directed product approach and has been actively providing a number of health insurance benefit plans for their customers.

Even though it is true that a large number of benefits come with these companies, it is not necessary that they would suit the needs of an individual. Although, it is advised that insurance policy should only be taken from one of the above mentioned, and you can often get quotes from all of them on a good health insurance quotes website. This comes in analogy with preferred electronic companies for best buy.
