Gastric Emptying Study: A Comprehensive Guide

Introduction

Gastric emptying study is a medical procedure used to evaluate how quickly food leaves the stomach. It is commonly performed to diagnose and manage digestive disorders, such as gastroparesis (delayed emptying) and dumping syndrome (rapid emptying). This article discusses the CPT code for gastric emptying study, its indications, preparation, procedure, interpretation, and clinical applications.

Indications

Gastric emptying study is indicated for individuals experiencing persistent symptoms suggestive of impaired gastric function, such as: * Nausea and vomiting after meals * Feeling full quickly after meals * Abdominal pain or bloating * Weight loss or failure to gain weight * Heartburn or acid reflux

Preparation

The preparation for a gastric emptying study typically involves: * Fasting for at least 8 hours before the procedure * Avoiding smoking and caffeine consumption for 24 hours before the study * Informing the healthcare provider about any medications or supplements being taken

Procedure

Gastric emptying study is performed using either a radioactive or non-radioactive tracer. The tracer is mixed with a liquid or solid meal and ingested by the patient. The patient then undergoes a series of imaging tests to monitor the movement of the tracer through the stomach. The test typically takes several hours to complete.

Interpretation

The gastric emptying study results are interpreted by comparing the rate of tracer clearance from the stomach to established normal values. Delayed emptying is diagnosed when the tracer remains in the stomach for an extended period (> 2 hours). Rapid emptying is diagnosed when the tracer clears from the stomach too quickly (< 1 hour).

Clinical Applications

Gastric emptying study is used to: * Diagnose gastroparesis and dumping syndrome * Evaluate the effectiveness of treatment for gastric emptying disorders * Monitor the progression of diseases that affect gastric function * Assess the nutritional status of patients with digestive disorders

Story Cases

* **Case 1:** A 45-year-old woman presented with nausea, vomiting, and abdominal pain after meals. Gastric emptying study revealed gastroparesis, which was treated with prokinetic medications. * **Case 2:** A 20-year-old man complained of feeling full quickly and experiencing diarrhea after meals. Gastric emptying study diagnosed dumping syndrome, which was managed with dietary modifications. * **Case 3:** A 65-year-old woman with diabetes underwent a gastric emptying study to assess her risk of developing gastroparesis. The results showed normal gastric function, indicating a low risk.

CPT Code for Gastric Emptying Study

The CPT code for gastric emptying study is 91204. It includes the tracer, imaging tests, and interpretation of the results.

Conclusion

Gastric emptying study is a valuable tool for diagnosing and managing gastric emptying disorders. The CPT code for gastric emptying study is 91204. By understanding the indications, preparation, procedure, interpretation, and clinical applications of gastric emptying study, healthcare professionals can effectively utilize this test to improve patient outcomes.
