93351-53 modifier

Nancy,
For example: exercise stress echo inconclusive, target not achieved, then the pt was sent home and he was rescheduled the other day for dobutamine stress echo.
In this case can we bill 93351 with modifier 53 on one day
dobutamine stress echo 93351 93320 93325 J1250 the other day

I mean inconclusive echo on 02/08/12(93351-53)
dobutamine stress echo on 02/09/12(93351,93220,93225,J1250)
