What 93586 covers
This add-on describes venographic imaging of the coronary sinus during evaluation of congenital heart disease. A congenital or interventional cardiologist typically performs it in a cardiac catheterization laboratory, using catheter-based contrast imaging to show the coronary sinus and its connections. The service includes catheter placement and the imaging supervision and interpretation associated with that venography.
Select this code when the coronary sinus is the venous structure imaged; other congenital venography codes identify different sites or collateral pathways. The report should support the need for coronary sinus imaging and document the anatomy evaluated and findings. Code 93586 is reported only with an eligible primary congenital cardiac catheterization procedure, such as codes 93593–93597, and is paid within that primary procedure's global period.

How to choose
- 93584Venography
- 93584 is selected for venography involving anomalous pulmonary venous return or a persistent superior vena cava. Use 93586 when the coronary sinus is the imaged structure.
- 93585Congenital venography
- 93585 focuses on the azygos or hemiazygos venous system, rather than coronary sinus anatomy.
- 93587Venography
- 93587 describes venovenous collateral imaging at or above the atrial level. 93586 identifies coronary sinus venography.
- 93588Congenital venography
- 93588 is for venovenous collaterals below the atrial level, not imaging directed at the coronary sinus.
93586 billing questions
When should 93586 be chosen instead of another congenital venography code?
Use 93586 when the venographic target is the coronary sinus. Codes 93584, 93585, 93587, and 93588 describe other venous structures or collateral pathways.
Can 93586 be reported by itself?
No. It is an add-on code and must be reported with a primary congenital cardiac catheterization procedure, such as an applicable code from 93593–93597.
Does 93586 include catheter placement and image interpretation?
Yes. The coronary sinus venography service includes catheter placement and radiological supervision and interpretation for that imaging.
What documentation supports reporting 93586?
Document why coronary sinus venography was performed, the structure and connections evaluated, and the imaging findings in the catheterization record.
How does the add-on payment rule affect 93586?
The code is paid within the global period of the primary procedure with which it is reported; it is not a standalone service.
