Prospect's Message of Hope for Healthier Tomorrows

Welcome to Prospect Medical.

Prospect Medical has a long history as a respected leader in managed healthcare.

Prospect Medical is comprised of owned and managed medical groups/IPAs as well as a managed services organization (MSO) operations, supporting all health plan delegated functions for medical groups / IPA Affiliates.


Combined, our affiliated medical groups, including the medical groups that we manage, are a significant provider of managed care services. Each of our medical groups is a network of independent physicians that contracts with HMOs. In diverse areas, HMOs often find it more efficient to outsource the responsibility of providing physician services through medical groups. This collaboration between HMOs and medical groups is a well-established model in the markets we serve and is designed to motivate physicians to practice preventive medicine and reduce unnecessary procedures.

Affiliation with a medical group allows independent physicians to build their practices and HMOs to more efficiently contract for physician services and outsource certain medical management and administrative functions associated with those activities.  


Our managed services organization (MSO) provides administrative support to our owned affiliates and managed medical groups/IPA.  These support services include claims payment, comprehensive medical management, credentialing, provider relationship management, customer service, utilization management, compliance programs and financial services.

The company started when Prospect Medical Group, Inc.—one of our medical groups—began growing through a series of acquisitions and affiliations beginning in 1995. This included our expansion from California-based Orange and San Bernardino counties with the acquisition of ProMed Health Care Administrators and its affiliated medical groups in June 2007. This transaction increased the number of HMO enrollees to 80,000. Today, we arrange for the care of more than 500,000 members in our 25 owned or managed networks of more than 11,000 doctors and specialists in six states.

Awarded Elite status by America’s Physician Group for 8 years in a row, our medical groups drive high quality, cost effective care for the members that we care for.

We believe that quality care means more than treating you when you are sick. To continually improve the health of the communities we serve, we offer a comprehensive health education library.

Prospect Medical contracts with most major health plans, and we serve all product lines, including commercial, Medicare, Medicaid, Medicare/Medicaid (Medi-Medi) and Health Insurance Exchange.
