The cost of running health plans in Minnesota increased at a faster pace during 2015, raising questions about whether the state is on the cusp of an expensive new trend.
Insurers spent a total of $1.69 billion on administrative expenses in 2015, up 11 percent from $1.52 billion the previous year, according to an April report from the Minnesota Department of Health.
Over the past 10 years, administrative costs at health plans have expanded as more people have found health insurance, including coverage gains through the federal Affordable Care Act (ACA).
But expanded coverage apparently isn't the only factor. Administrative costs have been growing on a per-person basis, the report finds, and on that basis in 2015 were at their highest point in a decade.
"The big question is: Is 2015 the beginning of a trend?" asked Stefan Gildemeister, the state's health economist. "Or is it just an outlier that may have to do with a delayed response of the health insurance industry to ACA requirements?"
Insurers pointed to numbers in the report showing that administrative spending actually has decreased as a share of all expenses. A decade ago, administrative costs accounted for 8.4 percent of all health plan spending, they point out, whereas the comparable figure in 2015 was 7.6 percent.
"Administrative spending has been and remains a small part of total costs, and is still lower as a percentage of total costs than it was 10 years ago," said Jim Schowalter, chief executive of the Minnesota Council of Health Plans, a trade group for insurers. "It's not driving health spending, obviously, but it's still there."
The health department report said the 7.6 percent figure in 2015 was noteworthy, because it follows a five-year period where the range held relatively steady between 7.1 percent and 7.3 percent. Complete data for 2015 is the most recent year that's currently available. Gildemeister noted the study can't pinpoint what drives spending changes.
