Administrative costs

A 2003 study published by the Blue Cross and Blue Shield Association (BCBSA) also found that health insurer administrative costs were approximately 11% to 12% of premiums, with Blue Cross and Blue Shield plans reporting slightly lower administrative costs, on average, than commercial insurers. For the period 1998 through 2003, average insurer administrative costs declined from 13% to 12% of premiums. The largest increases in administrative costs were in customer service and information technology, and the largest decreases were in provider services and contracting and in general administration. The McKinsey Global Institute estimated that excess spending on "health administration and insurance" accounted for as much as 21% of the estimated total excess spending ($477 billion in 2003).
