Cardiac catheterization
About 93588: Congenital heart venovenous collateral venography
Reports contrast venography of venovenous collateral vessels below the diaphragm during congenital heart catheterization.
This add-on captures contrast venography used during congenital cardiac catheterization to map venovenous collateral vessels located below the diaphragm. A congenital interventional cardiologist or other cardiac catheterization physician performs the injection and imaging in a catheterization laboratory. The target is the collateral venous channel below the diaphragm, rather than a collateral at or above it.
Report 93588 only with an eligible primary congenital heart catheterization service; it is not a stand-alone venography claim. Documentation should identify the below-diaphragm collateral being assessed and support that contrast venography was performed, including the injection and resulting images or interpretation. CMS classifies 93588 as an add-on, with payment made within the primary procedure’s global period. Select this code by the collateral’s anatomic level; use the corresponding code for venovenous collateral imaging at or above the diaphragm when that is the imaged site.
