It's 43 feet long, contains three dental chairs and has been the setting for thousands of cavity fills, tooth extractions and checkups for low-income dentistry patients over the years.
The mobile dental clinic operated by Minneapolis-based UCare is perhaps the most tangible example, supporters say, of how the health plan has gone the extra mile to topple barriers to care for people with public health insurance coverage.
But now, the dental clinic, like the HMO itself, is traversing an uncertain path with the state's decision to drop UCare as an option next year for most of the state's Medicaid and MinnesotaCare programs.
"That's the bulk of who we see in the mobile dental clinic," said Dr. Paul Schulz, a faculty member at the University of Minnesota School of Dentistry, which jointly operates the unit. "I'm very concerned."
To UCare supporters, the mobile dental unit is just one example of how UCare has stood out among health plans. Pointing to language services, transportation, and programs that target community needs, advocates say the HMO has led the way.
The prospect of forcing 369,000 UCare enrollees to switch to new health plans for next year is "outrageous," said Alfred Babington-Johnson of Stairstep Foundation, a Minneapolis group that works to expand access to health care among black Minnesotans.
"More than the other entities in the marketplace, UCare has demonstrated a genuine concern for their low-income clients and has shown a willingness to enter health-oriented collaborations with communities of color," Babington-Johnson wrote in an August letter to Gov. Mark Dayton.
In July, Dayton announced the results of a competitive bidding process that could save taxpayers $450 million, but will dramatically shake up the roster of HMOs and county-based groups that manage care in counties across the state.
