Official Description

Ultrasound guidance for vascular access requiring ultrasound evaluation of potential access sites, documentation of selected vessel patency, concurrent realtime ultrasound visualization of vascular needle entry, with permanent recording and reporting (List separately in addition to code for primary procedure)

Common Language Description

Ultrasound guidance for vascular access, as described by CPT® Code 76937, involves the use of ultrasound technology to assist healthcare professionals in safely and effectively accessing blood vessels. This procedure is particularly beneficial as it enhances the success rates of vascular access by minimizing the number of needle puncture attempts, thereby reducing the risk of complications such as iatrogenic injury and infection. The use of ultrasound not only improves patient comfort but also ensures a higher level of safety during the procedure. The ultrasound can be performed using two-dimensional (2D) imaging or Doppler Color Flow (DCF) techniques, both of which provide real-time visualization of the vascular structures. During the procedure, the ultrasound can be utilized in two imaging planes: short-axis (SAX) and long-axis (LAX). In the SAX approach, the imaging plane is oriented perpendicular to the vessel and needle, allowing the vessel to appear as an anechoic circle on the display screen, while the needle is visualized as a hyperechoic point in cross-section. Conversely, the LAX technique involves positioning the imaging plane parallel to the vessel, enabling the healthcare provider to view the vessel's direction across the screen, with both the shaft and tip of the needle visible as it advances toward the target vessel. Prior to the procedure, a thorough patient interview and review of medical records are essential to identify any anatomical considerations, previous procedures, and potential complications. The ultrasound evaluation of the selected access site is critical for differentiating between arteries and veins, assessing the size and patency of the vessel, determining its course and depth, and identifying any surrounding structures or adjacent pathology. Once the appropriate vessel is selected, the access site is prepared in a sterile manner, and ultrasound guidance facilitates real-time visualization of the needle entry during the vascular access procedure, which is reported separately from the primary procedure.

1. Indications

Ultrasound guidance for vascular access is indicated in various clinical scenarios where precise and safe access to blood vessels is required. The following conditions and situations warrant the use of this procedure:

  • Difficulty in locating veins: Patients with challenging venous access due to obesity, dehydration, or anatomical variations may benefit from ultrasound guidance to enhance the likelihood of successful access.
  • Previous failed attempts: In cases where prior attempts at vascular access have been unsuccessful, ultrasound guidance can provide a clearer visualization of the vessels, reducing the risk of further complications.
  • Need for central venous access: Procedures requiring central venous catheters, such as in critical care settings, often necessitate ultrasound guidance to ensure accurate placement and minimize risks.
  • Patient safety concerns: In patients with a history of complications from vascular access, such as hematomas or infections, ultrasound guidance can help mitigate these risks by providing real-time visualization.

2. Procedure

The procedure for ultrasound guidance for vascular access involves several critical steps to ensure accuracy and safety. Each step is outlined in detail below:

  • Step 1: Patient Preparation The first step involves preparing the patient for the procedure. This includes conducting a thorough interview to gather relevant medical history, assessing any anatomical issues, and reviewing previous procedures that may impact vascular access. The healthcare provider must also explain the procedure to the patient, addressing any concerns to ensure informed consent.
  • Step 2: Ultrasound Evaluation Following patient preparation, an ultrasound evaluation of the potential access site is performed. This evaluation is crucial for differentiating between arteries and veins, assessing the size and patency of the selected vessel, and determining its course and depth. The ultrasound also helps identify surrounding structures and any adjacent pathology that may affect the procedure.
  • Step 3: Site Preparation Once the appropriate vessel is identified, the access site is prepared in a sterile manner. This preparation is essential to prevent infection and ensure a safe environment for the procedure.
  • Step 4: Real-Time Visualization With the site prepared, the healthcare provider uses ultrasound guidance to achieve concurrent real-time visualization of the needle entry during the vascular access procedure. This step is critical as it allows for precise needle placement, reducing the likelihood of complications and improving the overall success rate of the procedure.

3. Post-Procedure

After the vascular access procedure is completed, several post-procedure care considerations must be addressed. The site should be monitored for any signs of complications, such as bleeding, hematoma formation, or infection. The patient should be advised on care for the access site, including keeping it clean and dry, and to report any unusual symptoms. Follow-up appointments may be necessary to assess the site and ensure proper healing. Documentation of the procedure, including the ultrasound findings and any complications encountered, is also essential for compliance and future reference.

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).
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
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.
