What percentage of medical expense insurance is represented by group health insurance through private insurance companies?

Group health insurance through private insurance companies typically accounts for a significant portion of the medical expense insurance market. The reason the percentage is around 90% is due to the prevalence and importance of employer-sponsored health plans in the United States. Many employers offer group health insurance as a benefit to attract and retain employees, resulting in a large number of individuals being covered under these plans. This widespread adoption helps create economies of scale that can lower costs for both insurers and insured individuals.

In contrast, individual health insurance plans, while essential, make up a smaller slice of the market. The high percentage indicative of group health insurance reflects the structure of the health insurance industry, where group plans are the primary means of coverage for a vast majority of people.
