Official Description

Angiography, extremity, unilateral, radiological supervision and interpretation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 75710 refers to a specific medical procedure known as angiography of the extremity, performed unilaterally, which involves the radiological supervision and interpretation of the imaging results. This procedure is essential for assessing the condition of the arteries in an extremity, which can include either the upper or lower limbs. During the angiography, a radiopaque contrast medium is utilized to enhance the visibility of blood vessels under fluoroscopy, allowing for a detailed examination of blood flow and the structural integrity of the arterial walls. The process typically begins with the insertion of a large bore needle into the appropriate artery, such as the femoral artery for lower extremities or the radial or brachial artery for upper extremities. A guidewire is then introduced through the needle, followed by the advancement of a catheter over the guidewire to the targeted area for imaging. Once positioned, a contrast dye is injected, enabling real-time visualization of blood flow as X-ray images are captured. These images are crucial for further analysis and can be compared with previous studies to monitor changes over time. The code 75710 specifically denotes the radiologist's role in supervising the imaging procedure for one side of the body, distinguishing it from other codes that may apply to bilateral studies or additional interpretations.

1. Indications

The angiography procedure represented by CPT® Code 75710 is indicated for various clinical scenarios where assessment of the arterial integrity and blood flow in an extremity is necessary. The following conditions may warrant this procedure:

  • Peripheral Artery Disease (PAD) A condition characterized by narrowed arteries reducing blood flow to the limbs, often leading to symptoms such as leg pain during physical activity.
  • Suspected Arterial Occlusion When there is a suspicion of blockage in the arteries that may be causing ischemia or inadequate blood supply to the extremities.
  • Trauma In cases of injury to the extremities where vascular damage is suspected, angiography can help visualize the extent of the injury.
  • Preoperative Assessment Prior to surgical interventions, angiography may be performed to evaluate the vascular anatomy and plan the surgical approach.
  • Evaluation of Aneurysms To assess the presence and characteristics of aneurysms in the arteries of the extremities.

2. Procedure

The angiography procedure using CPT® Code 75710 involves several critical steps to ensure accurate imaging and assessment of the extremity's vascular system. The following outlines the procedural steps:

  • Step 1: Accessing the Artery The procedure begins with the selection of the appropriate access site, which is typically the femoral artery in the groin for lower extremity studies or the radial or brachial artery in the upper arm for upper extremity studies. A large bore needle is carefully inserted into the chosen artery to gain access to the vascular system.
  • Step 2: Guidewire Introduction Once the needle is in place, a guidewire is introduced through the needle. This guidewire serves as a pathway for the subsequent catheter, allowing for precise navigation through the vascular system.
  • Step 3: Catheter Advancement A catheter is then advanced over the guidewire to the desired location within the arterial system. This step is crucial as it positions the catheter at the site where imaging will be performed, ensuring that the area of interest is adequately visualized.
  • Step 4: Injection of Contrast Medium After the catheter is properly positioned, a radiopaque contrast medium is injected through the catheter. This contrast dye enhances the visibility of the blood vessels during imaging, allowing for a clearer assessment of blood flow and arterial structure.
  • Step 5: Real-Time Imaging As the contrast medium flows through the arteries, real-time X-ray images are obtained. These images capture the movement of the dye through the vascular system, providing valuable information about blood flow and any potential abnormalities.
  • Step 6: Image Recording The X-ray images are recorded for further analysis. These images can be reviewed in detail and compared with previous examinations to assess any changes in the vascular condition over time.

3. Post-Procedure

After the completion of the angiography procedure coded as CPT® 75710, several post-procedure care considerations are essential for patient safety and recovery. Patients are typically monitored for any immediate complications, such as bleeding at the access site or adverse reactions to the contrast medium. It is common for patients to be advised to rest and avoid strenuous activities for a specified period following the procedure. Additionally, instructions regarding the care of the access site, including keeping it clean and dry, are provided. Follow-up appointments may be scheduled to discuss the findings from the angiography and to determine any further necessary interventions based on the results. Overall, the post-procedure phase is crucial for ensuring patient safety and effective recovery.

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.
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.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
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).
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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
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
GC This service has been performed in part by a resident under the direction of a teaching physician
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.
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
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
GY Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
GV Attending physician not employed or paid under arrangement by the patient's hospice provider
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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
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.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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.
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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.)
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).
99 Multiple modifiers: under certain circumstances 2 or more modifiers may be necessary to completely delineate a service. in such situations modifier 99 should be added to the basic procedure, and other applicable modifiers may be listed as part of the description of the service.
