Official Description

Radiologic examination, esophagus, including scout chest radiograph(s) and delayed image(s), when performed; double-contrast (eg, high-density barium and effervescent agent) study

Common Language Description

A radiologic examination of the esophagus, identified by CPT® Code 74221, is a diagnostic imaging procedure that utilizes contrast materials to enhance the visibility of the esophagus during X-ray imaging. This examination employs indirect ionizing radiation to capture images of the esophagus, which is a muscular tube that connects the throat to the stomach. The use of contrast agents, such as high-density barium and an effervescent agent, allows for a clearer distinction of the esophageal structures by highlighting differences in density and composition. The procedure typically begins with one or more scout chest radiographs, which are preliminary X-ray images taken from a front-to-back (anteroposterior) view while the patient is in an erect or semi-reclined position. These initial images help to visualize the surrounding structures of the esophagus before the administration of the contrast material. In a double-contrast study, the patient ingests a barium sulfate mixture that coats the esophagus, along with an effervescent agent that creates gas in the stomach, enhancing the contrast between the barium and the air. This combination allows for a more detailed examination of the esophagus, aiding in the diagnosis of various conditions such as ulcers, tumors, inflammation, scarring, and obstructions. Following the ingestion of the contrast materials, a series of X-ray images are captured to assess the esophagus's condition. Delayed images may also be taken if the movement of the contrast through the esophagus is particularly slow, ensuring that all relevant details are captured for accurate diagnosis. After the imaging is complete, the physician reviews the images, identifies any abnormalities, and provides a comprehensive written interpretation of the findings, which is essential for guiding further clinical management.

1. Indications

Radiologic examination of the esophagus using CPT® Code 74221 is indicated for the evaluation of various esophageal conditions. The following are specific indications for performing this procedure:

  • Ulcers - To identify the presence of ulcers in the esophagus, which may cause pain and difficulty swallowing.
  • Tumors - To detect tumors or abnormal growths that may obstruct the esophagus or indicate malignancy.
  • Inflammation - To assess inflammation of the esophagus, which can result from conditions such as esophagitis.
  • Scarring - To evaluate scarring or strictures that may affect the esophagus's ability to function properly.
  • Obstruction - To investigate any obstructions that may impede the passage of food or liquids through the esophagus.
  • Other Abnormalities - To identify any other structural abnormalities that may affect esophageal function.

2. Procedure

The procedure for a double-contrast radiologic examination of the esophagus involves several key steps, which are detailed as follows:

  • Step 1: Patient Preparation - The patient is prepared for the examination, which may include fasting for a specified period prior to the procedure to ensure that the stomach is empty. This preparation is crucial for obtaining clear images of the esophagus.
  • Step 2: Scout Radiographs - The examination begins with the acquisition of one or more scout chest radiographs. These initial X-ray images are taken in an anteroposterior view while the patient is positioned either erect or semi-reclined. The purpose of these scout images is to visualize the surrounding structures of the esophagus and to establish a baseline before the administration of contrast material.
  • Step 3: Administration of Contrast Material - Following the scout images, the patient is instructed to swallow a high-density barium sulfate mixture. In addition, an effervescent agent is administered to create gas in the stomach, which enhances the contrast during imaging. This combination allows for a more detailed view of the esophagus.
  • Step 4: Imaging - X-ray images of the esophagus are taken at various intervals as the barium and gas move through the esophagus. The radiologist may take multiple images to capture different phases of the swallowing process and to ensure comprehensive visualization of the esophagus.
  • Step 5: Delayed Imaging (if necessary) - If the movement of the contrast material is particularly slow, delayed images may be obtained to ensure that all relevant details are captured for accurate diagnosis.
  • Step 6: Image Review - After the imaging is complete, the physician reviews all captured images, noting any abnormalities or areas of concern. This review is critical for diagnosing any esophageal conditions.
  • Step 7: Interpretation and Reporting - Finally, the physician provides a written interpretation of the findings based on the images reviewed. This report is essential for guiding further clinical management and treatment decisions.

3. Post-Procedure

After the completion of the double-contrast radiologic examination of the esophagus, patients may be advised to drink plenty of fluids to help eliminate the barium from their system. It is common for patients to experience some mild discomfort or changes in bowel habits following the procedure due to the barium contrast. Patients should be informed that their stool may appear white or light-colored for a short period after the examination. Additionally, any significant findings or abnormalities noted during the imaging will be discussed with the patient, and further diagnostic or therapeutic steps may be recommended based on the results. It is important for patients to follow any specific post-procedure instructions provided by their healthcare provider to ensure a smooth recovery and to address any concerns that may arise.

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.
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
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
CR Catastrophe/disaster related
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
GA Waiver of liability statement issued as required by payer policy, individual case
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
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
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).
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.
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.
