Cardiac catheterization
About 93584: Congenital SVC venography
Reports contrast venography of an anomalous or persistent superior vena cava performed to define systemic venous anatomy during congenital heart catheterization.
This add-on captures contrast imaging used to map an anomalous or persistent superior vena cava in a patient with congenital heart disease. A congenital or pediatric interventional cardiologist typically performs the study in a cardiac catheterization laboratory, injecting contrast through a catheter and documenting the vessel’s course and connections with fluoroscopic images. The findings can clarify systemic venous anatomy relevant to the catheterization or a planned intervention.
Report 93584 only with a primary procedure; it is not a stand-alone venography service. The record should identify the congenital anatomy being evaluated and support that the contrast study addressed the anomalous or persistent superior vena cava. Distinguish this target from other venous structures represented by neighboring congenital venography codes. CMS places payment for this add-on within the primary procedure’s global period, so report it in conjunction with the applicable primary procedure.

93584 billing questions
When is 93584 the right congenital venography code?
Use it when the contrast study maps an anomalous or persistent superior vena cava. Choose a different congenital venography code when the imaged structure is another venous system.
Can 93584 be billed by itself?
No. It is an add-on code and must be reported with a primary procedure.
What documentation supports reporting 93584?
Document the anomalous or persistent superior vena cava being evaluated and the contrast imaging performed to show its course or connections.
How does CMS treat payment for this add-on?
CMS places payment for 93584 within the primary procedure’s global period. Report it with that primary procedure rather than as a stand-alone service.
How does 93584 differ from 93585?
93584 addresses an anomalous or persistent superior vena cava. 93585 is for venography of the azygos or hemiazygos system.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
