What 33229 covers
During this procedure, the clinician opens the pacemaker pocket, disconnects and removes the existing pulse generator, and connects a replacement generator to the existing multiple-lead system. It is commonly performed by an electrophysiologist or other cardiac device specialist when a pacemaker generator reaches its replacement threshold, including because of battery depletion. The procedure may take place in a hospital or an ambulatory setting.
Select this code for a generator exchange in a multiple-lead pacemaker system; the number and type of leads, not the reason for replacement, distinguish it from single- and dual-lead generator replacement codes. The operative report should support removal of the old generator, placement of the replacement, and the multiple-lead system involved. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

33229 billing questions
How is this code distinguished from the single- and dual-lead replacement codes?
Choose based on the pacemaker system’s lead configuration: this code is for a multiple-lead system, while 33227 and 33228 represent single- and dual-lead systems.
Does this code include replacement of the pacing leads?
It describes exchange of the pulse generator connected to the existing multiple-lead system. Lead insertion, repositioning, or repair is a different service and should be supported and coded separately when performed.
Can this code be used for an ICD generator exchange?
No. This code is for a pacemaker generator; an ICD generator replacement belongs to the ICD procedure code family.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
How does Medicare handle another procedure performed in the same session?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction.
Can an assistant or co-surgeon be reported for this procedure?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
