Gastric Emptying Study: A Comprehensive Guide to CPT Codes

Introduction

A gastric emptying study (GES) is a medical procedure used to evaluate how quickly the stomach empties its contents. It is often performed to diagnose and monitor conditions that affect stomach function, such as gastroparesis and dyspepsia. CPT codes are specific codes used by healthcare providers to bill for medical services and procedures, including GES.

Understanding CPT Codes for Gastric Emptying Studies

The CPT code for a gastric emptying study is 76075. This code includes the following services: * Administration of a liquid or solid meal containing a radioactive tracer * Monitoring of the stomachs emptying rate using gamma camera imaging * Interpretation of the results by a qualified physician

Indications for a Gastric Emptying Study

A GES may be recommended in the following situations: * Suspected gastroparesis (delayed stomach emptying) * Evaluation of dyspepsia (indigestion) * Monitoring the response to treatment for gastroparesis * Research studies on gastric function

Procedure

A GES typically involves the following steps: * The patient consumes a meal containing a radioactive tracer. * The patient lies under a gamma camera, which tracks the movement of the tracer through the stomach. * Images are taken at regular intervals over several hours to monitor the stomachs emptying rate.

Interpretation of Results

The results of a GES are typically expressed as a percentage of the meal that has emptied from the stomach at different time intervals. Normal gastric emptying rates vary depending on the type of meal consumed. *

Solid Meals: 10% emptied at 1 hour, 30% at 2 hours, 60% at 3 hours *

Liquid Meals: 50% emptied at 30 minutes, 80% at 60 minutes

Limitations

A GES may not be suitable for all patients, including those with: * Impaired kidney function * Recent radiation therapy to the abdomen * Pregnancy * Certain medical conditions that may interfere with the absorption of the tracer

CPT Code Variations

*

76076: Gastric emptying study with wireless motility capsule *

76077: Gastric emptying study with gastric tonometry

Reimbursement

The reimbursement for a GES varies depending on the type of meal used and the complexity of the procedure. According to the Medicare Physician Fee Schedule, the national average payment for a GES with a solid meal is approximately $700.

Case Study: Delayed Gastric Emptying

A 45-year-old woman presented with complaints of nausea, vomiting, and abdominal pain after meals. Her GES showed delayed gastric emptying, with only 20% of the solid meal emptied at 3 hours. She was diagnosed with gastroparesis and prescribed prokinetic medication, which significantly improved her symptoms.

Case Study: Dyspepsia

A 30-year-old man sought evaluation for chronic indigestion. His GES showed normal gastric emptying rates, suggesting that his symptoms were not related to a stomach motility disorder. Further testing revealed an ulcer in his small intestine, which was treated with antibiotics.

CPT Code and Billing Information

When billing for a GES, the following information should be included: * CPT code: 76075 * Type of meal used * Number of images taken * Interpretation of the results by a qualified physician

Conclusion

The CPT code for a gastric emptying study is 76075. GES is a valuable tool for diagnosing and monitoring conditions that affect stomach function. By providing detailed information about how quickly the stomach empties its contents, GES can help guide treatment decisions and improve patient outcomes.
