(Michigan) I had a extremely minor procedure done on my big toe (I had worn speedskating boots too tight and the nail had irritated the skin, apparently allowing in a very slight infection). I went into a podiatrist to see if something should be done, and he said that it's just a minor infection in the area, and the irritation I was feeling was caused by an inflamation right next to my toenail. He said he could simply use a few drops of a solution to "freeze" the area to numb it, pop it and drain it real quick and be done with it.
I said "ok, sure that's fine", because he made it seem like it was no big deal. He came in, fixed it, gave me some topical antibiotic cream, and I went on my way.
A few months later, I get a bill in the mail from them saying I owe them $200 for my portion of the insurance deductible (I later find out the whole procedure was billed to the insurance company at something around $350). I talk to the lady and tell her that "The doctor never said it was going to cost that much money, he made it seem like he could just take care of it for me while I was there as part of the visit". She said "Our policy is the doctors here don't talk financial with the patients, they don't know what our fee schedule is, you should have asked before you went in" (even though I didn't know what he was planning on doing, I was planning on just paying for an office visit, which has a $15 co-pay). Now they're saying if it isn't paid they'll go to collections.
So basically, they either grossly overcharged for a procedure, and/or they failed to represent to me the fact that the procedure was going to cost that much. If it was going to cost that much I would have gone elsewhere or just done it all myself. Basically, I feel like I walked into a building that said "Meet a famous actor, $15", then I walk in and shake the guy's hand and he says "want an autograph?" I get his autograph and he says "Oh, that's going to be $350 for the autograph, pay on the way out".
