preoperative visits

A patient was seen in the hospital for the following dates/services

4/18/2011 99221 dx 787.3, 787.01, 560.9
4/19/2011 99223 dx 560.9
4/20/2011 99223-57 dx 560.9
4/20/2011 42005 dx 560.9

Medicare denied dos 4/19/11 as inclusive and paid the other visits. I understand that the global period starts the day before the surgery. Should we have billed the 4/19 99223?

re: preoperative visits

These are all hospital admits. Why would you charge admits 3 consecutive days?

re: preoperative visits

I assume you meant to write the codes for subsequent visits.

Modifier 57 is used the day the decision for surgery was made. It will protect one E/M service. If the patient is in the hospital for multiple days before the surgery is scheduled and done, you will often lose one or more of the E/M days.
