Official Description

Echocardiography, transesophageal, real-time with image documentation (2D) (with or without M-mode recording); including probe placement, image acquisition, interpretation and report

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Transesophageal echocardiography (TEE) is a specialized imaging procedure that utilizes a high-frequency ultrasound transducer, which is mounted on the end of a flexible probe. This probe is carefully inserted through the mouth and advanced into the esophagus, allowing it to be positioned directly behind the heart. The primary function of the transducer is to emit ultrasound waves that penetrate the heart, with the reflected sound waves being captured and converted into visual images by a computer. These images are then displayed in real-time on a video monitor, providing dynamic insights into the heart's structure and function. TEE is particularly valuable for obtaining detailed two-dimensional images of the heart, as well as for assessing the movement of cardiac structures as they function. During the procedure, the transducer can be maneuvered within the esophagus to capture multiple views, enabling a thorough evaluation of both the left and right heart chambers, the heart valves, the pericardium, and other critical anatomical structures, including the aorta, pulmonary vessels, and the vena cava. Additionally, TEE may incorporate selective M-mode recording, which is a technique that provides specific time-motion data from a stationary ultrasound beam, superimposed on the two-dimensional images. This M-mode recording is particularly useful for precise cardiac measurements, such as assessing septal wall thickness and timing of valve movements. The use of CPT® code 93312 is appropriate when the physician performs the complete procedure, which includes probe placement, image acquisition, and the generation of a written report detailing the findings. In contrast, CPT® code 93313 is designated for instances where only the transesophageal probe placement is conducted, while CPT® code 93314 applies when only image acquisition and reporting are performed.

1. Indications

The transesophageal echocardiography (TEE) procedure is indicated for various clinical scenarios where detailed visualization of cardiac structures is necessary. The following conditions may warrant the use of TEE:

  • Evaluation of Cardiac Function: TEE is utilized to assess the overall function of the heart, including the evaluation of wall motion abnormalities and ejection fraction.
  • Assessment of Valvular Heart Disease: This procedure is indicated for detailed examination of heart valves, particularly in cases of suspected valvular stenosis or regurgitation.
  • Investigation of Atrial Septal Defects: TEE is effective in identifying and characterizing atrial septal defects and other congenital heart anomalies.
  • Detection of Thrombi: The procedure is often performed to detect the presence of thrombi in the left atrium, particularly in patients with atrial fibrillation.
  • Preoperative Assessment: TEE may be indicated prior to cardiac surgery to provide detailed anatomical information that can influence surgical planning.

2. Procedure

The transesophageal echocardiography procedure involves several critical steps to ensure accurate imaging and assessment of cardiac structures. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is typically positioned in a left lateral decubitus position to facilitate optimal access to the esophagus. Pre-procedure sedation may be administered to ensure patient comfort during the examination.
  • Step 2: Probe Insertion A flexible transesophageal probe, equipped with a high-frequency ultrasound transducer, is carefully inserted through the patient's mouth and advanced into the esophagus. The physician ensures that the probe is positioned correctly behind the heart to obtain the best imaging angles.
  • Step 3: Image Acquisition Once the probe is in place, real-time ultrasound imaging is initiated. The physician manipulates the probe to capture multiple views of the heart, allowing for a comprehensive evaluation of the cardiac chambers, valves, and surrounding structures.
  • Step 4: M-Mode Recording (if applicable) If necessary, selective M-mode recording is performed to provide detailed time-motion information regarding specific cardiac measurements, such as valve timing and wall thickness.
  • Step 5: Interpretation and Reporting After the imaging is complete, the physician interprets the acquired images and compiles a detailed report of the findings, which includes any abnormalities detected during the examination.

3. Post-Procedure

Following the transesophageal echocardiography procedure, patients are typically monitored for a short period to ensure that they recover from sedation and that there are no immediate complications. Patients may experience a sore throat or mild discomfort due to the probe insertion, which usually resolves quickly. It is important for patients to follow any specific post-procedure instructions provided by the healthcare team, including dietary restrictions or activity limitations. The results of the echocardiography are usually discussed with the patient during a follow-up appointment, where the physician will explain the findings and any necessary next steps in management or treatment.

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
GC This service has been performed in part by a resident under the direction of a teaching physician
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
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
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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).

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).
Q0 Investigational clinical service provided in a clinical research study that is in an approved clinical research study
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).
GA Waiver of liability statement issued as required by payer policy, individual case
AO Alternate payment method declined by provider of service
GW Service not related to the hospice patient's terminal condition
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
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.
47 Anesthesia by surgeon: regional or general anesthesia provided by the surgeon may be reported by adding modifier 47 to the basic service. (this does not include local anesthesia.) note: modifier 47 would not be used as a modifier for the anesthesia procedures.
56 Preoperative management only: when 1 physician or other qualified health care professional performed the preoperative care and evaluation and another performed the surgical procedure, the preoperative component may be identified by adding modifier 56 to the usual procedure number.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.
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.)
93 Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system : synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
