How to reply to patient. LUNAR study are not covered by insurance. The service date was covered and paid by patient insurance. United Health Care allowed $333.00, paid $273.00, and copayment $60.00. Please see patient message. I am participating in the LUNAR study so just wanted to make sure that the co-pay costs for my 2/20/24 visit are not covered by the study, and that I am supposed to pay that. I will go ahead and pay it but if someone could nonetheless confirm that I am responsible for it I would appreciate it
