I had septoplasty surgery to open nasal passages. A week later a 'follow up' visit, 3 weeks later another 'follow up' visit and another in July. I received the bill for this visit and was charged over $500, insurance paid $100, leaving me with $400 for each visit. It was an office visit. I paid $2200 between the DR and surgical center. I've asked the DR's office for a explanation as to why so much. I haven't received a response. I'm not sure what to do. I think this is crazy, am I wrong?
