CMS Pub. 100-03, ch. 1, § 20.13
HIS Bundle Study
CIM 50-3
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.
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. (See §20.12,
“Diagnostic Endocardial Electrical Stimulation.”)
