Official Description

Echocardiography, transesophageal (TEE) for monitoring purposes, including probe placement, real time 2-dimensional image acquisition and interpretation leading to ongoing (continuous) assessment of (dynamically changing) cardiac pumping function and to therapeutic measures on an immediate time basis

Common Language Description

Transesophageal echocardiography (TEE) is a specialized imaging technique used to obtain detailed images of the heart and its structures. This procedure is particularly valuable in situations where acute dynamic changes in cardiovascular function occur, such as during surgical interventions on the heart or aorta. TEE involves the placement of a probe equipped with a miniature high-frequency ultrasound transducer, which is inserted through the mouth and advanced into the esophagus. This positioning allows for closer proximity to the heart, enabling the acquisition of high-quality, real-time two-dimensional images. The ultrasound waves emitted by the transducer penetrate the heart and are reflected back, creating detailed images that are displayed on a video monitor. The continuous assessment of cardiac pumping function is crucial during procedures, as it allows for immediate interpretation of the heart's performance and the effects of any therapeutic measures being implemented. The monitoring physician plays a vital role in this process, as they are responsible for reporting any significant changes in cardiac function to the physician performing the intervention, facilitating timely adjustments to treatment to mitigate potential adverse effects on heart function.

1. Indications

The transesophageal echocardiography (TEE) procedure is indicated for monitoring purposes in various clinical scenarios where acute changes in cardiovascular function are anticipated. These indications include:

  • Cardiac Surgery Procedures involving the heart, where real-time monitoring of cardiac function is critical to ensure patient safety and effective management.
  • Aortic Interventions Surgical or interventional procedures on the aorta that may lead to dynamic changes in hemodynamics, necessitating continuous assessment of cardiac performance.
  • Acute Cardiac Events Situations such as myocardial infarction or severe arrhythmias where immediate evaluation of cardiac function is required to guide therapeutic interventions.

2. Procedure

The transesophageal echocardiography (TEE) procedure involves several key steps to ensure accurate monitoring of cardiac function:

  • Probe Placement The procedure begins with the careful placement of a specialized TEE probe. The patient is positioned appropriately, and the probe, which contains a high-frequency ultrasound transducer, is inserted through the mouth and advanced into the esophagus. This positioning is crucial as it allows the transducer to be in close proximity to the heart, providing clearer images.
  • Real-Time Image Acquisition Once the probe is correctly positioned, real-time two-dimensional images of the heart are acquired. The ultrasound waves emitted by the transducer penetrate the heart and are reflected back, creating detailed images that are displayed on a video monitor. This step is essential for visualizing the heart's structures and assessing its function dynamically.
  • Continuous Assessment Throughout the procedure, continuous assessment of cardiac pumping function is conducted. The monitoring physician interprets the images in real-time, allowing for immediate evaluation of any changes in cardiac performance. This ongoing assessment is vital for determining the effectiveness of therapeutic measures being implemented during the intervention.
  • Reporting Changes As the procedure progresses, the monitoring physician is responsible for reporting any significant changes in cardiac function to the physician performing the intervention. This communication is critical for making timely adjustments to treatment, ensuring that any adverse changes in heart function are addressed promptly.

3. Post-Procedure

After the completion of the transesophageal echocardiography procedure, the patient is monitored for any immediate post-procedural effects. It is important to assess the patient's recovery from sedation, as TEE often requires sedation for comfort. The monitoring team will ensure that the patient is stable and that there are no complications related to the probe placement. Additionally, the results of the echocardiography will be documented and communicated to the relevant healthcare providers to inform ongoing patient management and care decisions.

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
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).
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.
