Final answer:
To report an esophagogastroscopy without duodenal examination, append modifier -52. Modifier -52 is used to indicate a reduced service, applicable in cases where the full standard service isn't completed during procedures like endoscopies.
Step-by-step explanation:
To report an esophagogastroscopy where the duodenum is deliberately not examined, you should append modifier -52 if a repeat examination is not planned. This modifier indicates a reduced service because the entire scope of a standard service was not fully performed. For example, when a clinician decides not to examine the duodenum during an endoscopy procedure because it is not clinically pertinent, or a condition such as significant gastric retention precludes a safe examination, modifier -52 is relevant.To report esophagogastroscopy where the duodenum is deliberately not examined, or because the clinical situation precludes such an exam, you would append modifier -27 if repeat examination is not planned.
Endoscopic procedures like endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) provide insights into the state of abdominal organs. The former uses sound waves to create images from within, and the latter uses dye and X-ray to visualize the ducts of the gallbladder, liver, and pancreas. These procedures illustrate how specific endoscopic examinations require modifiers when they are not fully performed.
