About 33736: Operative revision of a heart chamber
Code 33736 reports operative revision of a heart chamber when the surgeon’s documented work matches this procedure rather than another cardiac repair.
Code 33736 represents a surgeon’s operative revision of a heart chamber. It belongs to a group of cardiac procedures that also includes repairs of congenital defects and abnormal venous connections. The operative report should identify the chamber revised and describe the work performed; the CMS short description alone cannot distinguish 33736 from the neighboring chamber-revision code, 33735.
Select 33736 from the full procedure description and operative details, rather than from the shared abbreviated label. Medicare assigns it a 90-day surgical global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are paid at 50%. Modifier 50 is inappropriate for this service. An assistant surgeon may be paid; co-surgeons require supporting documentation. Medicare does not permit team surgery for 33736.

33736 billing questions
How is 33736 distinguished from 33735?
Both have the same CMS short description. Compare the full procedure descriptions with the operative report; the abbreviated labels alone do not establish which chamber-revision code fits.
What operative documentation supports 33736?
The report should identify the heart chamber involved and explain the revision performed, allowing selection of 33736 rather than a code for venous or other defect repair.
Is postoperative care separately reported?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for 33736?
No. Medicare’s bilateral adjustment does not apply to this heart-chamber procedure, so modifier 50 is inappropriate.
How does Medicare handle additional procedures or surgeons?
In the same session, the highest-valued procedure is paid in full and other procedures at 50%. An assistant surgeon may be paid; co-surgeons need supporting documentation, and team surgery is not permitted.
