What 93584 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

93585Congenital venography
Use 93584 for an anomalous or persistent superior vena cava; use 93585 when the venography targets the azygos or hemiazygos system.
93586Coronary sinus venography
93584 maps an anomalous or persistent superior vena cava, while 93586 addresses venography of the coronary sinus.
93587Venography
93587 is for veno-venous collaterals at or above the diaphragm, rather than an anomalous or persistent superior vena cava.

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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
