A computed tomographic angiography (CTA) of the pelvis is a specialized imaging procedure that utilizes advanced technology to visualize the blood vessels within the pelvic region. This procedure involves the use of contrast material, which enhances the visibility of the blood vessels during imaging. The process begins with the patient being positioned on a CT table, where an intravenous line is typically inserted into a blood vessel, often in the arm or hand. This line is essential for administering the contrast material, which is injected to improve the clarity of the images obtained. In some cases, non-contrast images may also be captured as part of the procedure, providing additional context and detail. The CTA employs a combination of computed tomography and angiography techniques, allowing for the acquisition of multiple images that are subsequently processed using computer technology. This processing creates detailed, three-dimensional cross-sectional views of the pelvic blood vessels, which are then displayed on a computer monitor for analysis. The procedure is designed to provide comprehensive insights into the vascular structures of the pelvis, aiding in the diagnosis and evaluation of various medical conditions. After the imaging is completed, a radiologist reviews and interprets the CTA images, ensuring that the findings are accurately documented for further medical assessment and decision-making.

The computed tomographic angiography (CTA) of the pelvis is indicated for various clinical scenarios where detailed visualization of the pelvic blood vessels is necessary. The following conditions may warrant the use of this imaging procedure:
The procedure for performing a computed tomographic angiography (CTA) of the pelvis involves several key steps that ensure accurate imaging and assessment of the pelvic blood vessels. The following outlines the procedural steps:
Post-procedure care following a computed tomographic angiography (CTA) of the pelvis typically involves monitoring the patient for any immediate reactions to the contrast material. Patients may be observed for a short period to ensure there are no adverse effects, particularly if they have a history of allergies to contrast agents. Hydration is often encouraged to help flush the contrast material from the body. Patients may also receive specific instructions regarding follow-up appointments or additional imaging if necessary. It is important for the radiologist to communicate the findings of the CTA to the referring physician, who will then discuss the results with the patient and determine any further steps in their care plan.

| 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. | 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 | 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 | 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. | MG | The order for this service does not have applicable appropriate use criteria in the qualified clinical decision support mechanism consulted by the ordering professional | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 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. | 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. | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | CR | Catastrophe/disaster related | CT | Computed tomography services furnished using equipment that does not meet each of the attributes of the national electrical manufacturers association (nema) xr-29-2013 standard | ET | Emergency services | GA | Waiver of liability statement issued as required by payer policy, individual case | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | GW | Service not related to the hospice patient's terminal condition | LT | Left side (used to identify procedures performed on the left side of the body) | MA | Ordering professional is not required to consult a clinical decision support mechanism due to service being rendered to a patient with a suspected or confirmed emergency medical condition | MC | Ordering professional is not required to consult a clinical decision support mechanism due to the significant hardship exception of electronic health record or clinical decision support mechanism vendor issues | ME | The order for this service adheres to appropriate use criteria in the

this service and the related data was provided to the furnishing professional | RT | Right side (used to identify procedures performed on the right side of the body) | 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 | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XP | Separate
