Aetna Inc. is a leading American managed health care company specializing in traditional and consumer-directed health insurance and related services, including medical, pharmaceutical, dental, behavioral health, long-term care, and disability plans.

The company's name is derived from Mount Etna, reflecting its enduring presence and transformation in the insurance industry.

Aetna has been a pioneer in the Medicare space, issuing the nation's first Medicare claim in 1966.
