Ross-Loos Medical Group

From Wikipedia, the free encyclopedia

Ross-Loos Medical Group was a comprehensive prepaid health services plan with 29 medical offices throughout Los Angeles, Orange, Riverside and San Bernadino Counties and a large multi-specialty hospital located on Temple Street in Los Angeles, California.

Ross-Loos was established in 1929 by two physicians, Donald E. Ross and H. Clifford Loos, older brother of writer Anita Loos. The plan consisted of monthly payments which assured benefits of socialized medical and hospital care to over two thousand employees of the Los Angeles County and Department of Water and Power and their families.

The founders believed that health care could be improved by combining prepayment of services, eliminating the financial barriers faced by patients at the time of needed care, with the sharing of medical records and the ease of consultation in a medical group. The focus was on the improvement of medical care quality, rather than financial success, and many of the concepts in these plans built on a public health approach that encouraged prevention. These plans included prenatal care, well-baby visits, and immunizations in standard benefit packages, with small or no copayments, in an era when even the hospital costs of maternity stays were often excluded from traditional insurance.

Thus, Ross-Loos Medical Group was the first "health maintenance organization" (HMO) in the United States, a name that came into being in the 1970s.

Over several years many other employee groups, mostly governmental, joined the plan. Ross-Loos was so successful that the first small medical office on Grand Avenue in [Los Angeles] expanded into an enormous organization with nineteen medical offices and a large multi-specialty hospital on Temple Street in Los Angeles by 1979.

In 1980, Ross-Loos Medical Group was purchased by the Insurance Company of North America (INA) HealthPlan (see [HMO International] and [California Medical Group] and merged into its medical office operations which created over twenty-nine medical office locations throughout southern California. Its new name was "INA and Ross-loos HealthPlans". This new operational name was in existence a short time until 1982 through a merger of the Insurance Company of North America (INA) and Connecticut General (CG) their names changed to become CIGNA. Ross-Loos Medical Group, became now known as CIGNA HealthPlans of California and was merged into the large CIGNA Employee Benefits devision. In 1997 CIGNA made a decision to divest itself of it's "owned delivery system" or "staff model" (see HMO - staff model) and sold their operations to MedPartners. This sale to MedPartners also caused a new name change of the CIGNA "owned delivery system" in Southern California, The system bacame merged into the recient perchase in southern [California] by [Medpartners] of the "Friendly Hills Medical Group". In 1999 MedPartners was placed in recevership due to inability to manage the combined operations of its southern California subsidiares" Friendly Hills Medical Group", Talbert Medical Group, Mullikan Medical Group, [Vinyard Medical Group] and Riverside Medical Group. These "[MedPartners]" owned facilies were divested and sold to physician owned delvery systems or closed. The MedPartner name was changed to [Caremark Rx], the Talbert Medical Group was sold to the physicians of the Talbert Medical Group, the Mullikan, Riverside and Vinyard Medical Groups were eventually closed. The Friendly Hills Medical Group, was acquired by KPC Global Care. KPC "see Chadhuri Medical Group" and continued operations for a short while, however it too was placed into receivership by the State of California Department of Corporations in 1999 and closed down. The Original [Ross-Loos Medical Group] facilities were closed and "Medical Center" - Hospital on Temple Street in Los Angeles, was sold to "The Queen of Angles Hospital".

The original Ross-Loos Medical Group, medical offices and hospital sadly ended with this sale in 1999 some 70 years after its beginning.

The Names: "Ross-Loos", "Ross Loos Medical Group" & "Ross Loos HealthPlans" are still owned by [CIGNA] Corporation and remain registered with the state of [California], Department of Corporations, Department of Insurance and the Department of Managed Care.
