Founded in 1977, SCAN provides healthcare coverage to Medicare beneficiaries in California, Arizona, Texas and Nevada, serving more than 285,000 members.

That changed when it was awarded a contract from the federal government as one of four sites nationwide to pilot the Social Health Maintenance Organization (SHMO) demonstration program.

In November 1984, under a three-and-a-half-year contract with the federal government, SCAN was officially licensed as a health plan in California.

[8] Between 1996 and 1998, SCAN more than doubled its membership by expanding into three Southern California counties (Orange, Riverside and San Bernardino).

That growth was fueled by the launch of a range of new products including: Affirm, the first ever LGBTQ+ Medicare Advantage plan and SCAN's expansion into Texas and Nye County, Nevada.

In late 2022, SCAN announced that it and CareOregon had entered into a definitive agreement to combine as a mission-driven not-for-profit healthcare organization under the name HealthRight Group.

Pending regulatory approval, the combined entity will have revenues of $6.8B and will serve nearly 800,000 health plan members through its Medicare and Medicaid managed care offerings.

In 2022, SCAN was also named to U.S. News & World Report's 2023 list of Best Medicare Advantage Companies for the fifth consecutive year.

IAH also provides a resource and referral line to connect seniors and their caregivers to needed services and support in Los Angeles, Orange, Riverside and San Bernardino counties and a virtual senior center for older adults in all the communities served by SCAN Health Plan.
