|Modifier -57, Decision for Surgery:
An Evaluation and Management service resulted in the initial decision to
perform surgery during the E/M encounter.
Let's describe this modifier:
An OB/GYN sees a patient who complains with severe abdominal pain. It turned
out (through ultra sound, radiology and all other diagnostic testing and
documentations), the patient is having an ectopic pregrancy. The OB/GYN
performs the laparoscopic surgery on the same day. The E/M encounter will
then be reported with modifier 57 which resulted to decision for surgery. The
laparoscopic surgery should also be reported as performed on the same day
without a modifier.
