Notes: These data show the net cost of private health insurance per private enrollee (including Blue Cross/Blue Shield, commercial insurance, HMOs, and self-insured plans), as calculated by the Centers for Medicare and Medicaid Services. Net cost of insurance is the difference between premiums earned and benefits incurred, and includes insurers’ costs of paying bills, advertising, sales commissions, and other administrative costs; net additions/subtractions from reserves; rate credits and dividends; premium taxes; and profits or losses. Private enrollment is estimated by CMS using the National Health Insurance Survey and the Current Population Survey.
