CPT code 74220 refers to a special type of imaging procedure used to examine the food pipe, known as the esophagus, by using a liquid that shows up well on X-rays. CPT 74220 represents “Radiologic examination, esophagus, including scout chest radiograph(s) and delayed image(s), when performed; single-contrast (eg, barium) study.”
Procedure Explanation:
This procedure involves taking a series of images of the esophagus after the patient drinks a substance that makes the esophagus visible on an X-ray. It includes a basic chest X-ray before starting and sometimes additional images after some time has passed. This technique helps doctors see the shape and functioning of the esophagus but does not include examining any other parts of the digestive system.
Common Names:
- Single-contrast esophageal study
- Barium swallow
- Esophagus X-ray
Relative Value Units (RVU):
The RVUs associated with this code are 0.6.
How This Procedure Appears:
- Operating Room Schedule Name: Esophageal radiology study
- Surgical Consent Form Name: Consent for esophageal X-ray examination
Typical Patients and Diagnoses:
This procedure is commonly used for patients who might have difficulty swallowing, persistent heartburn, or suspected abnormalities in their esophagus. For example, a person experiencing unexplained chest discomfort after eating could benefit from this examination to check for any blockages or narrowing of the esophagus.
Associated ICD-10 Codes:
- K21.0: Gastroesophageal reflux disease (GERD) with esophagitis, a condition where stomach acid frequently flows back into the esophagus, causing irritation.
- D50.9: Iron deficiency anemia, which could present with symptoms like difficulty swallowing.
- K22.2: Esophageal obstruction, a blockage that can lead to swallowing problems or chest pain.
Summary
In summary, code 74220 describes an imaging test that visualizes the esophagus using a contrast liquid, primarily to diagnose issues like obstruction or acid reflux. Typical ICD-10 codes associated with 74220 include K21.0 (GERD with esophagitis) and K22.2 (esophageal obstruction).
