We have been discussing when our doctor is scheduled to do caths at the hospital on a Wednesday and on Tues. he has a patient in office that he says "add to my cath schedule for Wednesday". Can we use the -57 modifier each time he makes that decision to cath the patient during the E&M visit the day before? Does anyone know the length of time you have before using the -57 is not valid. What I mean is can you only use it within 24hrs or 48hrs? Thank you for any input! Gail
