The Medicaid expansion promoted by the Affordable Care Act was a boon for St. Mary's Medical Center, the largest hospital in western Colorado. Since 2014, the number of uninsured patients it serves has dropped by more than half, saving the nonprofit hospital in Grand Junction more than $3 million a year.
But the prices the hospital charges most insured patients have not gone down.
"St. Mary's is still way too costly," says Mike Stahl, CEO of Hilltop Community Resources, which provides insurance to about half its nearly 600 employees and their families in western Colorado.
"We are not seeing the decreases in our overall health bills that I believe the community overall should be feeling," Stahl says.
He and other employers in Colorado hoped that, as hospitals saved millions of dollars in charity care from the Medicaid expansion, the institutions would pass along some of those savings, reducing the prices consumers pay as well as the overall health costs paid by employers.
A recent state report finds that didn't happen.
While hospitals are financially better off since the expansion, they have begun shifting even more of their costs to commercial health plans, according to the report.
The state researchers note the average hospital profit per each patient discharged rose to $1,359 in 2017 — twice the amount in 2009. For patients covered by commercial and employer-based health plans, the hospitals' profit margins per discharge rose above $11,000 in 2017, compared with $6,800 in 2009.
Julie Lonborg, a spokeswoman for the Colorado Hospital Association, says the state agency that did the study was biased against hospitals and had a "predetermined conclusion." Hospitals in the state are not doing as well as the report suggests, Lonborg says, noting that a third of them face operating losses.
And some insurers, she says, have not passed along to their customers the savings hospitals give the insurers.
Hundreds of thousands of state residents gained coverage under the Medicaid expansion, lowering Colorado's uninsured rate by half to 7 percent. In addition, hospitals' uncompensated care costs dropped by more than 60 percent, or more than $400 million statewide.
Kim Bimestefer, executive director of the Colorado Department of Health Care Policy & Financing, says that hospitals have used their expanded revenues to focus on adding services that provide high profits or expanding operations in wealthier areas of the state that often duplicate what is already available.
"They used those dollars to build free-standing [emergency departments], acquire physician practices [and] build new facilities where there was already sufficient capacity," she says. "Hospitals had a fork in the road to either use the money coming in to lower the cost-shift to employers and consumers or use the money to fuel a health care arms race. With few exceptions, they chose the latter."
Hospital's profit margin doubles
In written testimony to the state legislature last year, Colorado officials pointed to St. Mary's as an example of a hospital with high overhead and operating costs — factors they said can lead to higher insurance premiums.
The facility's profit margin was above 14 percent from 2015 to 2017, according to the latest available tax returns. Those figures are nearly double St. Mary's margin before expansion and twice the margin of the average U.S. hospital in 2017, according to American Hospital Association data.
Colorado is the first state to analyze whether hospital cost-shifting — often referred to as a "hidden tax" on health plans — dropped after Medicaid expansion.
But a conservative think tank in Arizona says hospitals there did not cut prices following that state's Medicaid expansion.
"Not only did [it] fail to deliver on the promises of alleviating the hidden health care tax, it allowed urban hospitals to increase charges on private payers dramatically," says a report from the Phoenix-based Goldwater Institute.
Some critics point out that hospitals are also benefiting because Congress has repeatedly delayed a key ACA provision that would have cut federal funding to hospitals that have large numbers of uninsured patients and patients on Medicaid.
The continuation of the program — called Medicaid disproportionate share hospital payments — has provided Colorado hospitals a total of $108 million.
How outside costs may factor in
The hospital industry disputes reports that it has merely pocketed profits from Medicaid expansion. Hospitals say many factors influence how much they charge employers and private insurers, including the need to upgrade technology and meet rising costs of health care and drugs.
Lonborg of the state hospital association says hospitals need to shift costs to private employers to make up for lower prices paid by Medicare and Medicaid, and to make up for care hospitals continue to give free of cost to the uninsured.
But, she adds, other factors, including the need to keep up with rapid population growth, have kept costs from dropping.
Janie Wade, chief financial officer for SCL Health, the Broomfield, Colo., hospital chain that owns St. Mary's and seven other facilities, says its costs are higher because it has sicker and older patients than most.
She says looking at just the hospital profit margins on St. Mary's IRS-990 form is not a fair assessment, because it doesn't take into account costs that are outside the hospital, such as its 93 physician practices. The hospital lost nearly $12 million on those doctor practices in 2017, she says.
Across all operations, the hospital's operating margin fell from 9.5 percent in 2015 to 4.5 percent in 2018, she adds.
Wade says the hospital used some of its new revenue to purchase 14 physician practices in recent years. That was designed, she says, not to ensure they send their patients to St. Mary's but to help keep those doctors in the city so they can staff important services such as trauma and maternity care.
"Medicaid expansion was a good thing and, of course, we supported it," Wade says.
But she points out that the hospital loses money on Medicaid and Medicare, which together cover more than three-quarters of its patients.
St. Mary's has sought to keep price increases for commercial insurers and employers to no more than the general inflation rate and has made rate even lower for some, according to Wade. If employers' rates have been rising more than that, she says, it's likely because insurers have been adding price increases.
Officials from Rocky Mountain Health Plans, one of Grand Junction's largest insurers and recently acquired by UnitedHealthcare, would not comment.
David Roper, who used to oversee employee benefits for the city of Grand Junction and now heads a local employer coalition, says the state report confirms what local businesses leaders have long known. "St. Mary's has no incentive to reduce its costs," he says.
Edmond Toy, a senior adviser for the nonprofit Colorado Health Institute, says the argument that pursuing the ACA policy would help lower insurance premiums "broadened the appeal of Medicaid expansion ... and conceptually it makes total sense."
But, he notes, health care analysts have long debated whether the higher prices hospitals charge people with private insurance are designed to make up for the losses they take on with Medicare, Medicaid and uninsured patients.
The state report shows how hospitals in heavily consolidated markets don't have to cut prices as their bottom line improves, Toy says. "They can charge whatever the market will bear."
Marianne Udow-Phillips, director of the Center for Health and Research Transformation at the University of Michigan, says hospitals have considerable bargaining power in many places because of health system consolidations and their purchases of many physician practices.
"It does appear Colorado hospitals have a strong negotiating position with payers, or payers there are not negotiating very effectively," Udow-Phillips says. "Hospitals are not going to give it away."
