About 33530: Repeat coronary bypass reoperation
Identifies reoperative work during repeat coronary bypass surgery performed more than one month after the original operation, alongside the primary CABG code.
This add-on identifies reoperative work during a repeat coronary artery bypass procedure after an earlier operation. A cardiothoracic surgeon may perform the current bypass in a hospital operating room when coronary disease or graft problems call for another surgical revascularization. The code distinguishes a qualifying reoperation from a first-time CABG; it does not describe the number or type of grafts used.
Report 33530 with the primary CABG code that describes the current procedure and graft configuration. The operative report should establish that this is a reoperation and document the date or timing of the original operation, showing that it occurred more than one month earlier. CMS classifies 33530 as an add-on: it is not billed alone, and its payment is tied to the primary procedure’s global period.

33530 billing questions
Can 33530 be billed by itself?
No. Report it only with the primary code for the current coronary bypass procedure.
What timing qualifies for this code?
The reoperation must occur more than one month after the original operation. Document the prior operation and its timing in the current operative record.
Does 33530 identify the number or type of bypass grafts?
No. The primary CABG code identifies the graft configuration and count; 33530 identifies the qualifying reoperative circumstance.
Is a history of prior heart surgery enough to report 33530?
No. The current service must be a reoperation for coronary artery bypass, and the record should support that reoperative service and the required interval.
