What 33141 covers
A cardiac surgeon uses a laser to create channels in the heart muscle as a revascularization treatment, typically for severe angina associated with coronary artery disease that cannot be adequately treated by conventional revascularization. Code 33141 describes this work when it is performed during the same operative session as another open cardiac procedure, rather than as a stand-alone operation. Coronary artery bypass surgery is a recognized example of a concurrent procedure.
Report 33141 as an add-on with the code for the primary cardiac procedure; it is not reported by itself. The operative report should identify the laser revascularization work and the other open cardiac procedure performed in the same session. CMS pays this add-on within the primary procedure's global period. Use 33140 when transmyocardial laser revascularization is performed without another open cardiac procedure in that session.

How to choose
- 33140Heart revascularization
- 33140 describes transmyocardial laser revascularization performed without another open cardiac procedure in the same session. Choose 33141 when the laser work accompanies another open cardiac procedure.
- 33533Arterial CABG
- 33533 reports an arterial coronary bypass procedure and can serve as the primary code when transmyocardial laser revascularization is also performed. It does not describe the laser work reported with 33141.
- 33510Coronary bypass
- 33510 reports a venous coronary bypass procedure and may be the primary procedure for 33141. It identifies the bypass work, not the concurrent transmyocardial laser revascularization.
33141 billing questions
When should 33141 be chosen instead of 33140?
Use 33141 when transmyocardial laser revascularization is performed in the same operative session as another open cardiac procedure. Use 33140 for the stand-alone transmyocardial laser revascularization procedure.
Can 33141 be reported by itself?
No. It is an add-on code and must be reported with the primary procedure performed in the same operative session.
What documentation supports reporting 33141?
The operative report should describe the transmyocardial laser revascularization and identify the other open cardiac procedure performed during that session.
How does the global period affect payment?
CMS pays 33141 within the global period of the primary procedure with which it is reported.
Is coronary artery bypass surgery a possible primary procedure?
Yes. Transmyocardial laser revascularization performed during the same session as coronary artery bypass surgery is a recognized use of 33141; report the applicable bypass code as the primary procedure.
