Cardiac Device Monitoring Codes

We had a representative who visited our office regarding the cardiac device monitoring codes. The representative informed us we could be billing every 3 months for the use of the devices. The cpt codes I have researched indictate interpertation,review, analysis, etc.....
Is there a code for billing just the use of the equipment?
