Ultrasonic guidance, intraoperative

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Ultrasonic guidance, intraoperative, as represented by CPT® Code 76998, refers to the use of ultrasound technology during surgical procedures to enhance visualization of internal structures. This technique employs sound waves that are beyond the range of human hearing to create images of the body's internal anatomy. The process involves emitting sound waves that penetrate various tissues, which then reflect back to the ultrasound device at different speeds depending on the density of the tissues they encounter. These reflected sound waves are transformed into electrical signals, which are subsequently displayed as real-time images on a monitor. This imaging capability is crucial for surgeons as it allows them to accurately identify target structures, assess the location and depth of incisions, and monitor the progress of the surgery. It is important to note that this code is specifically not applicable for ultrasound guidance used in tissue ablation procedures, as those are categorized and reported under different codes.

1. Indications

Ultrasonic guidance, intraoperative (CPT® Code 76998) is indicated for use in various surgical procedures where enhanced visualization of internal structures is necessary. The following conditions or scenarios may warrant the use of this technique:

  • Complex Surgical Procedures In surgeries that involve intricate anatomical areas, ultrasonic guidance aids in accurately locating and navigating around critical structures.
  • Minimally Invasive Surgeries In procedures that require small incisions, ultrasound can help ensure precision in targeting the surgical site without extensive exploration.
  • Biopsy Procedures When performing biopsies, ultrasound guidance assists in accurately positioning instruments to obtain tissue samples from specific areas.
  • Fluid Drainage In cases where fluid accumulation needs to be drained, ultrasound can help locate the fluid collection accurately.

2. Procedure

The procedure utilizing ultrasonic guidance involves several key steps to ensure effective imaging and surgical assistance. The following outlines the procedural steps:

  • Step 1: Preparation The surgical team prepares the patient and the surgical site, ensuring that all necessary equipment, including the ultrasound machine, is ready for use. The patient is positioned appropriately to allow optimal access to the area of interest.
  • Step 2: Application of Ultrasound Gel A conductive gel is applied to the skin over the area where the ultrasound probe will be placed. This gel facilitates the transmission of sound waves between the probe and the skin, enhancing image quality.
  • Step 3: Probe Placement The ultrasound probe is positioned on the skin, and the technician or surgeon begins to emit sound waves. The probe captures the returning echoes from the internal structures, which are processed to create real-time images on the monitor.
  • Step 4: Visualization and Guidance As the procedure progresses, the surgeon uses the ultrasound images to visualize the target structures, making real-time adjustments to their approach based on the feedback provided by the ultrasound guidance.
  • Step 5: Completion of the Procedure Once the surgical objectives are achieved, the ultrasound guidance is concluded, and the surgical site is closed as per standard surgical protocols.

3. Post-Procedure

After the use of ultrasonic guidance in a surgical procedure, standard post-operative care protocols are followed. This may include monitoring the patient for any immediate complications related to the surgery. The surgical site is typically assessed for signs of infection or other adverse reactions. Patients may be advised on specific care instructions, including how to manage pain, signs of complications to watch for, and follow-up appointments for further evaluation. The use of ultrasound guidance generally contributes to improved surgical outcomes, potentially leading to shorter recovery times due to its precision and minimally invasive nature.

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.
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
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
LT Left side (used to identify procedures performed on the left 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
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
CR Catastrophe/disaster related
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.
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).
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).
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.
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.
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).
