Most likely nothing, medical expenses are no where near at-cost like they should be. Even assuming that they go up, you can't expect anyone not to "consume" medical care. I'm not going to deny someone treatment because it might cost me a few more pennies or dollars, that would be comically villainous.
The equilibrium would be treating medical care as a public good just like highways or firefighting, but insurance companies and hospital-owning equity firms actively expend resources to prevent that.
