What 93585 covers

This add-on service captures catheter-based contrast imaging of the azygos or hemiazygos venous system in a patient with congenital heart disease. A congenital cardiac catheterization team may use it to define an unusual venous route or connection, such as an azygos pathway in a patient with interrupted inferior vena cava. The imaging can help explain catheter course and venous return or guide procedural planning.

Report 93585 only with an eligible primary congenital heart catheterization, such as codes 93593–93597; it is not a stand-alone service. The record should support why this specific venous territory was imaged and document the catheter injection and resulting images or interpretation. CMS classifies the code as an add-on and pays it within the primary procedure’s global period.

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

93584Venography
Use 93585 for azygos or hemiazygos imaging; 93584 identifies venography directed at an anomalous or persistent superior vena cava.
93586Coronary sinus venography
Use 93586 when the coronary sinus is the target. 93585 is specific to the azygos or hemiazygos venous system.
93587Venography
93587 addresses venovenous collateral vessels at or above the heart; 93585 describes imaging of the azygos or hemiazygos system.
93588Congenital venography
93588 addresses venovenous collateral vessels below the heart. Use 93585 when the imaged target is the azygos or hemiazygos system.

How is 93585 different from 93584?

93585 is for imaging the azygos or hemiazygos system. 93584 concerns venography of an anomalous or persistent superior vena cava.

When would 93585 be more appropriate than 93586?

Choose based on the vessel imaged: 93585 addresses the azygos or hemiazygos system, while 93586 addresses the coronary sinus.

What documentation supports reporting 93585?

Document the clinical reason for imaging this venous pathway, the catheter-based contrast study, and the resulting images or interpretation.

How does the add-on payment rule affect billing?

CMS requires 93585 to accompany a primary procedure and places payment within that procedure’s global period.

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.
