Item/Service Description
The HIS Bundle Study is a specialized type of electrocardiography requiring catheterization of the right side
of the heart and is a recognized diagnostic procedure.
Indications and Limitations of Coverage
Medicare coverage of the procedure would be limited to selected patients: those with complex ongoing
acute arrhythmias, those with intermittent or permanent heart block in whom pacemaker implantation is
being considered, and those patients who have recently developed heart block secondary to a myocardial
infarction. When heart catheterization and the HIS Bundle Study are performed at the same time, the
program will cover only one catheterization and a small additional charge for the study.
When a HIS bundle cardiogram is obtained as part of a diagnostic endocardial electrical stimulation, no
separate charge will be recognized for the His bundle study.
