Help with next steps in disputed bill
My wife went to the ER for what was ultimately a kidney stone back in May. We were in the ER for about 4 hours. The bill came to roughly $4600, after insurance it is $3150 for me to pay. I asked for an itemized bill, and on the itemized bill there is a $895 charge for IV fluids. She never received IV fluids. She did receive IV medications, which is also on the itemized bill. I disputed the charge and appealed it and they denied the appeal. They said "no she received the IV fluids, that/s what her records say" but absolutely 100% she did not.
I've received no good explanation for this and I swear the hospital billing office is gaslighting me now and on this last phone call they said "are you sure you're not mis-remembering".... absolutely not, my wife is a nurse and is acutely aware of the therapies she received.
I'm a bit lost at this point as to next steps. I've filed a formal letter with the hospital billing office, which they said they have not received (it's been 6 weeks). Any recommendations?
