Yeah, I guarantee United Healthcare getting to deny paying for these is not going to stop the homeless person from making these calls. It's just going to stick the hospital with the bill, most likely.
And in fact, one of the major criticisms of this arrangement is that it provides an opportunity for private firms to rake in big profits based on fixed fees paid by taxpayers and reduced service offered by the administrating company. United Healthcare is extremely profitable in this area. https://www.macpac.gov/subtopic/managed-cares-effect-on-outc...
