IN Physician Associates IPA “IN” is an Independent Physician Association (IPA) comprised of several IPAs located across the state of California, currently serving Los Angeles and Orange counties.

IN’s business model was uniquely designed by leading managed care innovators to reduce Provider and Payer administrative efforts and to expand patient access by entering into one contract with practitioners and Health Plans on behalf of multiple IPAs.

IN recently partnered with a Restricted Knox-Keene licensed entity, Access Senior Healthcare, Inc., giving IN Physician Associates the opportunity to work with WellCare, Scan, and Humana in a global risk arrangement.
