CPT Code for Gastric Emptying Study: Essential Information for Medical Billing

Introduction

A gastric emptying study (GES) is a medical procedure used to evaluate the rate at which the stomach empties its contents. This test is commonly performed to diagnose and monitor conditions that affect gastric motility, such as gastroparesis and pyloric stenosis. Understanding the CPT code for gastric emptying study is crucial for accurate medical billing and reimbursement.

Overview of Gastric Emptying Study

A gastric emptying study typically involves consuming a radiolabeled meal, such as eggs and toast, and then undergoing a series of abdominal X-rays or scans to track the movement of the food through the stomach. The rate of gastric emptying is calculated based on the time it takes for 50% of the meal to leave the stomach.

Indications for Gastric Emptying Study

A gastric emptying study may be recommended for individuals who experience symptoms suggestive of impaired gastric motility, including: * Nausea and vomiting * Abdominal pain and bloating * Early satiety * Weight loss * Gastroesophageal reflux disease (GERD)

CPT Code for Gastric Emptying Study

The CPT code for gastric emptying study is 74145. This code includes the following components: * Administration of a radiolabeled meal * Performance of abdominal X-rays or scans * Interpretation of results

Additional Considerations

* CPT Modifier -52: This modifier may be appended to the CPT code to indicate a follow-up examination performed within 48 hours of the initial study. * CPT Modifier -RT: This modifier may be appended to the CPT code to indicate that the study was performed in real time, using fluoroscopy.

Case Studies

Case 1: A 50-year-old woman presented with complaints of persistent nausea, vomiting, and abdominal pain. A gastric emptying study revealed a delayed emptying rate, consistent with a diagnosis of gastroparesis. Case 2: A 3-month-old infant was admitted to the hospital with failure to thrive and recurrent vomiting. A gastric emptying study showed pyloric stenosis, a narrowing of the outlet of the stomach. Surgical correction was successful in resolving the symptoms. Case 3: A 45-year-old man underwent a gastric emptying study as part of a preoperative evaluation for bariatric surgery. The study confirmed that the patient had normal gastric motility and was a good candidate for the procedure.

Benefits of Gastric Emptying Study

* Helps diagnose and monitor gastrointestinal disorders that affect gastric motility * Provides objective data on the rate of gastric emptying * Guides treatment decisions and follow-up care * Improves patient outcomes by ensuring timely intervention

Statistics

* According to the National Institutes of Health, gastroparesis affects approximately 1 in 10,000 people in the United States. * Pyloric stenosis is the most common cause of vomiting in infants under 3 months of age, with an incidence of 2-3 per 1,000 live births.

Conclusion

Understanding the CPT code for gastric emptying study is essential for accurate medical billing. This procedure plays a crucial role in diagnosing and managing gastrointestinal disorders that affect gastric motility, leading to improved patient outcomes. By adhering to the appropriate CPT code and modifiers, healthcare providers ensure proper reimbursement and contribute to the efficient delivery of medical care.
