2025 CPT code 75898
(Active) Effective Date: N/A Revision Date: N/A Diagnostic Radiology - Angiography Radiology Feed
Follow-up angiography through an existing catheter after transcatheter therapy, embolization, or infusion (excluding thrombolysis).
Modifiers 26 (professional component only), TC (technical component only), and 59 (distinct procedural service) may apply depending on the circumstances of the service delivery.Payer policies may vary regarding the use of modifier TC.
Medical necessity is established by the need to assess the success of previous interventional radiology procedures, detect complications, or monitor the vascular status after treatment.Documentation must support the clinical indication for the follow-up study.
The radiologist is responsible for injecting contrast material, guiding the catheter using fluoroscopy, interpreting the images to assess the vascular status, and documenting the findings.Post-procedure monitoring for bleeding or complications may also be included depending on the facility's protocols.
In simple words: This code describes a follow-up X-ray examination of blood vessels using a dye and a catheter already in place from a prior treatment.The doctor will use this to check on the blood vessels after treatment, such as blocking off blood flow to a tumor or injecting medicine. This is not used for breaking up blood clots.
This CPT code, 75898, encompasses the radiological supervision and interpretation of a follow-up angiography performed via an existing catheter.This procedure is indicated after prior transcatheter therapy, embolization, or infusion, excluding thrombolysis. The service includes contrast injection, fluoroscopic guidance, vessel measurements, and completion angiography. Diagnostic angiography performed concurrently with the therapeutic procedure and influencing treatment decisions is separately reportable using modifier 59.
Example 1: A patient with a brain arteriovenous malformation (AVM) undergoes embolization.A follow-up angiography via the existing catheter is performed to assess the effectiveness of the embolization and detect any residual AVM nidus. This would be coded 75898., A patient with a renal artery stenosis receives a stent placement. A follow-up angiography is performed through the existing catheter to assess stent patency and exclude any complications such as stenosis or thrombosis. This would be coded 75898., A patient undergoes uterine fibroid embolization. A follow-up angiography is done to assess the extent of embolization and exclude any complications like non-target embolization. This would be coded 75898.
* Detailed clinical indication for the procedure.* Description of prior transcatheter therapy, embolization, or infusion.* Documentation confirming the use of an existing catheter.* Images of the post-intervention angiogram.* Physician's interpretation of the angiographic findings.* Anesthesia administration notes if applicable.* Note of any post-procedure complications or bleeding.
** This code is specifically for follow-up studies.If the initial diagnostic angiogram is performed on the same day as the therapeutic procedure, code it separately.
