C8004 is the authoritative medical code for Simulation angiogram with use of a pressure-generating catheter (e.g., one-way valve, intermittently occluding), inclusive of all radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance necessary to complete the angiogram, for subsequent therapeutic radioembolization of tumors. This classification is used in medical billing and clinical recording to specify the clinical criteria for simulation angiogram with use of a pressure-generating catheter (e.g., one-way valve, intermittently occluding), inclusive of all radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance necessary to complete the angiogram, for subsequent therapeutic radioembolization of tumors (HCPCS Level II C8004), ensuring healthcare documentation aligns with current federal coding standards.

Billing Status: Processed within HCPCS Level II standards. CMS regulatory guidelines apply.
