About C8004
C8004 is an HCPCS Level II code in the C series (outpatient PPS (temporary codes)), describing simulation angiogram with use of a pressure-generating catheter (e.g., one-way valve or occlusion balloon, intermittently or temporarily occluding), inclusive of all radiological supervision and interpretation, intraprocedural roadmapping, and imaging guidance necessary to complete the angiogram, for subsequent therapeutic radioembolization of tumors.
It was added to HCPCS effective 04/01/2025, and its current record took effect 10/01/2026.
Its Medicare coverage code is "D", meaning special Medicare coverage instructions apply.
The October 2026 quarterly update changed this code's record.
