Staff here is really kind but I was given a price for a CT and then I was billed for more, even though I was told I wouldn't be billed for more, especially not $500+ more since the self pay option was way less than that. Had I known this, I would've self paid instead of paying a higher rate through insurance. I know the healthcare industry exists to rip people off but I was really shocked and disappointed considering I received great customer service up until then, when they gave little negotiation with payment plans and didn't care that I was given the wrong amount.
