GAO Reports That Blues Dominate Many Small Group Markets

UnitedHealth Group units also have a big presence

Business owners with fewer than 50 employees in some states may feel as if they already buy health coverage through a single-payer health care system.

Researchers at the U.S. Government Accountability Office have published data supporting that conclusion in a report on competition in the small group health insurance market prepared at the request of Sen. Olympia Snowe, R-Maine; Sen. Christopher Bond, R-Mo.; and Sen. James Talent, R-Mo.

Regulators in California, New Hampshire and New Mexico did not respond to the survey at all, while regulators in seven other states could not or would not give the GAO researchers any small group market concentration statistics.

Another six states told the GAO how many carriers were licensed to sell small group coverage in their jurisdictions but could not provide any market share data.

In theory, at least three carriers are licensed to sell small group health coverage in all of the jurisdictions that participated in the GAO survey.

But a single health insurance carrier accounted for at least 50% of 2004 small group sales in nine of the 35 jurisdictions that provided small group market data, and a single carrier accounted for at least 75% of 2004 small group sales in four jurisdictions, according to the GAO researchers.

In most states, Blue Cross and Blue Shield companies are the biggest small group carriers, but a unit of UnitedHealth Group Inc., Minnetonka, Minn., is the biggest small group carrier in six jurisdictions.

Throughout the participating jurisdictions, the median market share of the largest small group carrier increased to 43% in 2004, from 33% in 2002, the GAO researchers write.

The median small group market share of all Blue Cross and Blue Shield companies in the reporting states increased to 44%, from 34%.

John Dicken, a GAO director, notes in a letter introducing the market share findings that the agency relied on help from regulators.

“We did not verify the information provided by the states,” Dicken writes.
