Expand/CollapseHISTORICAL NOTE

Blue Cross and Blue Shield of Minnesota was created in a June 1, 1972 merger of Minnesota Blue Cross and Blue Shield of Minnesota. The organization and its affiliates provide a variety of products and services, including health plans for employers and individuals; life insurance; long-term care plans; pharmacy benefits management; administrative services for self-insured groups; managed care services for workers' compensation; behavioral health care; and health and wellness programs. It administers the federal Medicare programs, and serves as the writing carrier for the Minnesota Comprehensive Health Association. It also offers a variety of other employee health benefits services through several for-profit subsidiaries. In 2004 it was the largest health plan in Minnesota, providing health coverage to more than 2.6 million members.

Minnesota Blue Cross was a nonprofit organization incorporated as the Minnesota Hospital Service Association. Organized by a group of Minnesota hospitals in 1933, it was Minnesota's first health plan and was based in St. Paul. The Association was one of the 90 approved non-profit plans in the United States and Canada, authorized by contracting hospitals to furnish hospital care through contracting hospitals to groups of employed persons and their families. These plans were known as "Blue Cross Plans" and each plan served a particular area. The contracting hospitals of the Minnesota Blue Cross Plan agreed to furnish hospital service according to the subscriber's contract and were reimbursed out of the monthly payments made by subscribers to the Minnesota Hospital Service Association. Minnesota Blue Cross operated as a non-profit corporation, and not under the state insurance laws. A companion plan, called Mii, incorporated in 1954 as Minnesota Indemnity, Inc. and organized under the insurance laws of Minnesota, helped pay for medical-surgical care. It was owned and operated by the Minnesota Hospital Service Association. These two organizations (MHSA/Blue Cross and Mii) made health care service on a pre-payment basis available to residents of Minnesota.

Minnesota Medical Service Inc., also known as Blue Shield of Minnesota, was a voluntary, non-profit surgical plan sponsored by the medical profession of Minnesota. It was for many years based in Minneapolis. Promotional work for subscribers enrollment in the Blue Shield Plan was carried on in conjunction with enrollment of Blue Cross subscribers. Blue Shield of Minnesota was formally organized in 1945 with its operating supervision being through the attorney general of Minnesota. Blue Shield benefits began to be sold in Minnesota in 1947.

Blue Cross and Blue Shield were separate organizations, with separate boards of directors and chief executive officers. The Blue Shield product was marketed by Blue Cross under an "expense sharing" contract. This arrangement continued through November 1959 when by mutual agreement the two decided to discontinue joint operations and become competitors. Shortly after this time Blue Cross began offering medical/surgical coverage through Mii. Blue Shield later entered the hospital coverage field with its Blue Shield Hospital Rider.

In April 1970 it was disclosed that Blue Shield was in serious financial difficulty, and Blue Cross was asked by the state insurance department, the attorney general, and the governor to assume operation of Blue Shield, which it agreed to do on April 27. A management agreement was implemented at that time, and the two plans operated under that agreement until May 17, 1972 when the corporate members of each body approved a formal merger of the two corporations into Blue Cross and Blue Shield of Minnesota effective June 1, 1972.

The historical information above was taken from Corporate Report Fact Book 2000, from the company's web site, and from materials found within the collection.

Expand/CollapseSCOPE AND CONTENTS

Subject files include correspondence and memoranda; articles of incorporation and bylaws; employee newsletters; company-produced pamphlets, brochures, and promotional literature; employee and member handbooks; financial reports; statistical data; news releases (1965-1979); provider directories; sample contracts; and some speeches and writings. There are some proceedings of the Minnesota State Medical Association House of Delegates (1960). There is some historical information about Blue Cross-Blue Shield of Minnesota and its predecessor organizations; biographical data on the organizations' officers; information about special "enabling legislation" that pertained to the company, the company's role as a participant in the Medicare program, and information about the corporate merger (1972) of Minnesota Blue Cross and Blue Shield of Minnesota. There are files containing information about health maintenance organizations (HMOs). Correspondents in the collection include officers and employees of Blue Cross-Blue Shield of Minnesota and its predecessors, television and radio stations, and various other individuals.

Photographs include images of Twin Cities-area home office buildings of Blue Cross-Blue Shield and its predecessors, including photos of construction projects; photos of executives and employees; office scenes; the company's use of electronic data processing equipment; photographs of office parties, dinners, and picnics; and some photos of then-Minnesota Governor Harold Stassen apparently signing the "enabling legislation" (1941). There are photographs of hospital buildings, hospital administrators, medical staff, and patients. There are some negatives, and there is one sheet of color slides.

The collection includes magazine and newspaper advertisements that document various advertising campaigns in the 1960s and 1970s. There are several 16mm movies concerning health and wellness issues, and one video recording.

Contents of two time capsules from the 1950s and 1970 are also included.

Most of the material in the collection probably originated in the public relations department of Blue Cross-Blue Shield of Minnesota.
