Wiki modifier 53 used by physician for discontinued surgery at ASC

[Betty7101]

I have a physician claim that keeps being denied as invalid modifier for use of modifier 53 to report a discontinued surgery due to complications to the patient that was performed in an ASC. I am seeing information that modifier 53 is not approved for use for outpatient hospital services. Is this correct? or is there support info that it is allowed?

Hi! I am an ASC biller and the ASC modifier is either 73 if the patient did not have anesthesia, or 74 if the patient did undergo anesthesia. Hope this helps!

That statement refers to the hospital/facility billing.
The advice by @MGable1018 also refers to the facility billing.
I am not aware of any reason -53 would be invalid for the physician's surgery claim. When billing -53, many carriers will request the medical records and/or a letter of explanation. I would try to get an explanation from the payor.
