Two things:

Hospitals do consult on EMS calls at times, often without billing for it.

Not all hospitals bill for every little thing, that really depends on the hospital and how they are funded. For example there are a number of children's hospitals that are funded by grants, donations and endowments. And some hospitals like the VA hospital system are funded by the government to serve specific segments of the population.

They don't bill on a per-call basis, but you can be sure that if a hospital is providing medical control services to an EMS agency there is a contract in place and they are being compensated for it (either a flat annual fee, or by some other means)
