I went to a dentist on the 19th for an exam. I need quite a bit of work done so after doing an x-ray and getting a 3d scan they set me up in a little room and tele-doc'd me from their office with a care coordinator and a dentist. They provided a treatment plan that totaled over $6,000 dollars. I cringed but I am really nervous with dentists due to a lot of work I had done as a teenager and teeth issues throughout my life... so I went ahead and said sure since they were keen to offer me 10-15% off the total. The work in question was: teeth cleaning, an extraction, one root canal, a bridge and a biopsy on some tissue they said looked weird where I had molars removed previously. I wasn't happy to pay before the work was done but since it was so much and seemed about right (I figured, what do I know, they're the pros?) I'd take the discount. We did the root canal same day since there was an opening. And that's it. That is the work that was done along with the x-rays. When I got home I inspected my invoice and immediately noticed discrepancies. For instance, dental codes such as D3221 and D3330 that cannot be billed together. A $350 charge for antibiotics I never received. Multiple instances of them billing me instead of my insurance for things that were covered, etc. I contacted them the next day via a form on their website and received a call the next morning. They told me I had to discuss it with my care coordinator and assured me she would call same day. Later that night, I also called their office hoping to speak with their office's billing department and they again stated that I could only resolve this with my care coordinator. It has now been a week and they have not reached out to me via phone, email or text message. Recently I went ahead and emailed their office and stated that due to the reasons I stated above and their lack of communication that I would be issuing a charge back with my credit card companies (I had to use two cards to cover the bill) within 48 hours if they did not reach out. I also stated that I would contact the dental board in my state for their fraudulent billing. It has since been 48 hours and again, no communication. My question is simple: is there some time-frame I have to give them or am I in the right thus far? I don't want to get slapped down the road with some claims that I didn't give them enough time to respond and since their legal team had to get involved I owe x amount yada yada... It feels like a really big deal, but I really need to get work done soon (an extraction that was part of the bill I paid for but didn't have done, the root canal is now open and needs a crown to finish it) and I obviously need the money to pay for that before I can schedule these things. Thank you for your help! Location: California (LA county)
