What is Health Insurance?
Health care insurance is a form of insurance that pays for medical expenditures incurred due to a medical condition. These charges might be connected to hospitalization costs, the cost of medications, or the cost of physician consultations. These are the top 10 health care insurance companies in the USA.
There are several private healthcare insurance experts in the United States. However, according to the Insurance Information Institute, life/annuity and property/casualty insurers also issue similar coverage, often referred to as accident and healthcare insurance.
By 2020, direct written premiums in the accident and health insurance market will total $1.25 trillion, up almost 84 percent from $680 billion in 2011.
According to the National Association of Insurance Commission, the top 10 insurers combined wrote 55.3 percent of the overall US market (NAIC).
