Congenital cardiac catheterization
About 93587: Congenital venovenous collateral venography
Reports catheter-based venography to assess venovenous collateral pathways at or above the diaphragm during a congenital heart catheterization.
This add-on describes contrast venography used to evaluate venovenous collateral pathways in a patient with congenital heart disease when the pathways are at or above the diaphragm. A congenital or interventional cardiologist typically performs the catheter work in a cardiac catheterization laboratory, with imaging used to show the collateral anatomy. It is distinct from venography directed at a named structure such as the coronary sinus or azygos system.
Report 93587 only with a qualifying primary procedure; it is not a stand-alone service. The record should identify the venovenous collateral pathway and its location, and support why its anatomy was evaluated. CMS treats the code as an add-on paid within the primary procedure’s global period. Distinguish it from 93588 when the venovenous collateral is below the diaphragm, and from other congenital venography add-ons when the study targets a specifically named structure.

93587 billing questions
How is 93587 distinguished from 93588?
Use 93587 for venovenous collateral pathways at or above the diaphragm. Code 93588 describes the corresponding assessment below the diaphragm.
Can 93587 be billed by itself?
No. CMS identifies it as an add-on code that must be reported with a primary procedure.
Which documentation supports reporting 93587?
Document the venovenous collateral pathway assessed, its location at or above the diaphragm, and the imaging performed to evaluate it.
Is this the code for coronary sinus venography?
No. Coronary sinus venography is represented by 93586. Use 93587 for venovenous collateral pathways at or above the diaphragm.
How does CMS handle payment timing for this add-on?
CMS places payment for 93587 within the global period of the primary procedure with which it is reported.
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.
