Wiki 52 vs. 53 modifier

I think either 52 or 53 would be ok

Modifier 52 has this indication -
Under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. Under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. This provides a means of reporting reduced services without disturbing the identification of the basic service.

Modifier 53 has this indication -
Under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. Due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. This circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure.

And both will probably result in a slightly less payment than the procedure without either modifier.
