Urography, antegrade, is a radiological procedure designed to visualize the anatomy and function of the kidneys and ureters. This procedure is essential for assessing urinary drainage and diagnosing various conditions affecting the urinary tract. It involves the injection of a radiopaque contrast medium, which enhances the visibility of these structures during imaging. The contrast can be administered through a percutaneously placed needle or tube, or via an indwelling catheter, allowing for a detailed examination of the renal pelvis, ureters, and the flow of urine. Antegrade urography encompasses several specific procedures, including pyelostogram, nephrostogram, and ureteropyelogram, which are utilized to identify abnormalities such as strictures, stones, and tumors. Additionally, this technique is valuable for evaluating the status of previously placed nephrostomy, pyelostomy, or ureterostomy catheters, as well as for visualizing implanted ureters in patients with an ileal conduit. The procedure typically begins with the administration of a local anesthetic to minimize discomfort, followed by the insertion of a needle guided by fluoroscopy to the target site, where the contrast medium is injected. This results in the capture of radiologic images that provide critical information regarding the upper urinary tract and its function. It is important to note that CPT® Code 74425 specifically refers to the radiological supervision and interpretation of the antegrade urography procedure, which includes the analysis of the obtained images and the generation of a comprehensive written report detailing the findings.

Antegrade urography is performed for various clinical indications, primarily to evaluate the urinary system's structure and function. The following conditions may warrant this procedure:
The antegrade urography procedure involves several critical steps to ensure accurate imaging and assessment of the urinary system. The following outlines the procedural steps:
After the antegrade urography procedure, patients may be monitored for any immediate complications or adverse reactions to the contrast medium. It is essential to ensure that the patient is stable and that there are no signs of infection or bleeding at the injection site. Patients may be advised to drink plenty of fluids to help flush the contrast material from their system. Follow-up imaging or assessments may be scheduled based on the findings from the procedure, and a detailed report of the results will be provided to the referring physician for further evaluation and management.

| 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. | 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). | GC | This service has been performed in part by a resident under the direction of a teaching physician | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | 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). | 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. | 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. | CC | Procedure code change (use 'cc' when the procedure code submitted was changed either for administrative reasons or because an incorrect code was filed) | FY | X-ray taken using computed radiography technology/cassette-based imaging | GZ | Item or service expected to be denied as not reasonable and necessary | LT | Left side (used to identify procedures performed on the left side of the body) | PD | Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | RT | Right side (used to identify procedures performed on the right side of the body) | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | 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 | 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 | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
