93230 coding for 48 or 78 hours

Best answers
I have asked this question before, but I need some clarification. CPT code 93230 if for 24 hour monitoring. If a patient is being monitored for 48 or 72 hours how would I code.
Would I code 93230 for each date; or would I code 93230 for the initial date, and 93230 modifiers 52 for the subsequent days?
