Defibrillation in procedure

Hello all,

Having a "discussion" with an MD about non elective defibrillation during a cath. Patient crashed and non-elective defibrillation done to revive patient. MD is insistent that we bill for it. Insistent that we find way to bill this. Help with explanation, please? Does anyone have any documentation to help? Already gave her documentation about elective defib. Don't know where to go from here. Have pulled in another coder as well as our lead.
