Additional Notes

Complaint: I received a bill from CRNA ****** T. ******* c/o Monox Billing Service ACCT# ********* on 02 June 2014. The bill states it is a Third Notice when in fact it is a First Notice. I called and spoke with ******* #*** who stated that she did not know I had TRICARE after I informed her that I was active duty military and all of my medical is covered 100%. ******* also stated that ****** **** ******* was not aware of my insurance through the military. I informed ******* that I was a patient at Bay City Surgery Center and when I filled out my patient paperwork it has my insurance information included. ******* stated that ****** T. ******* would not be aware of that information, although my anesthesia was performed by ****** T. ******* at Bay City Surgery Center on the day of the procedure (service) 11/15/13. ******* also stated that she requested the insurance information from ******* at Bay City Surgery Center and was refused my insurance information. I have had issues with Bay City Surgery Center in that I had to make numerous requests for my medical records. They refused to give me my medical records and when I visited their office on 18 March 2014, I was only provided a few copies of my medical record which included very little information about my medical treatment at Bay City Surgery Center. I complained to ****** (office manager) and after a couple of attempts was finally sent my complete medical record. Monox Billing Service is attempting to defraud the government by sending me a bill for $3000. Monox Billing Service and ****** T. ******* made no attempts at filing a claim with Tricare for the services provided.

Desired Settlement: Monox Billing Service/****** T. ******* need to file their claim with Tricare. Also, I do intend to further my complaints across the Internet and with Bay City Surgery Center.

Business Response: Our office only represents and bills for **** ******* CRNA for anesthesia services.  We 

did not receive the patients insurance information.  We called the patient and sent her a
statement requesting insurance information.
She complained that we should have it as the surgery center had the information.  We
did get the information from the surgery center, we only sent 1 statement to this patient.
We have verified that the insurance will pay the bill and we accept the rates paid for
military patients.
She will only receive another statement if she has a copay after the insurance pays.
At this time we are waiting for the check to be sent from the insurance.
Thank you
******* ******
