Official Description

Angiography through existing catheter for follow-up study for transcatheter therapy, embolization or infusion, other than for thrombolysis

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 75898 refers to the procedure of performing angiography through an existing catheter specifically for follow-up studies related to transcatheter therapy, embolization, or infusion, excluding thrombolysis. This procedure is essential for assessing the effectiveness of previously conducted transcatheter interventions. During this follow-up angiography, a contrast agent is injected through the catheter that was already placed during the initial procedure. This allows for the visualization of the treatment site through imaging techniques. The primary goal is to evaluate the outcomes of the transcatheter therapy, which may involve embolization—where blood vessels are intentionally blocked—or infusion—where medication is delivered directly to a specific area. The resulting images from this angiography will help determine if the desired therapeutic effects, such as the occlusion of targeted blood vessels in embolization or the successful delivery of medication in infusion, have been achieved. A comprehensive written interpretation of the angiographic findings is also provided to document the results of the follow-up study.

1. Indications

The procedure associated with CPT® Code 75898 is indicated for the following conditions:

  • Follow-up Evaluation This procedure is performed to assess the outcomes of previously conducted transcatheter therapies, including embolization or infusion procedures.
  • Assessment of Occlusion In cases where embolization has been performed, angiography is used to determine if there is partial or complete occlusion of the targeted blood vessel(s).
  • Evaluation of Infusion Results For infusion procedures, this angiography helps to identify whether the desired therapeutic results have been achieved.

2. Procedure

The procedure for CPT® Code 75898 involves several key steps that ensure a thorough follow-up evaluation of the transcatheter therapy performed.

  • Step 1: Catheter Utilization The procedure begins with the use of an existing catheter that was previously placed during the initial transcatheter therapy. This eliminates the need for a new catheter insertion, thereby reducing patient discomfort and procedural risks.
  • Step 2: Contrast Injection A contrast agent is then injected through the existing catheter. This contrast material is crucial as it enhances the visibility of the blood vessels and the treatment site during imaging.
  • Step 3: Imaging Acquisition Following the injection of the contrast, imaging studies are conducted to capture detailed images of the area of interest. These images are essential for evaluating the effectiveness of the prior embolization or infusion procedure.
  • Step 4: Interpretation of Results After the imaging is completed, a written interpretation of the follow-up angiography is generated. This report provides a detailed analysis of the findings, including whether the desired outcomes, such as occlusion or successful medication delivery, have been achieved.

3. Post-Procedure

Post-procedure care for CPT® Code 75898 typically involves monitoring the patient for any immediate complications related to the angiography. Patients may be observed for signs of bleeding or discomfort at the catheter insertion site. Additionally, the results of the follow-up angiography should be discussed with the patient, including any further treatment options or necessary follow-up procedures based on the findings. Recovery time may vary depending on the individual patient's condition and the complexity of the initial procedure, but generally, patients can expect to resume normal activities shortly after the angiography, barring any complications.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
GC This service has been performed in part by a resident under the direction of a teaching physician
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
LT Left side (used to identify procedures performed on the left side of the body)
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)

X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
2G Etv6, commonly called tel, gene associated with  t(12;21) (acute leukemia) tel (leukemia)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
