Gastric Emptying Study: An In-Depth Guide to CPT Code and Procedure

Gastric emptying studies (GES) are important diagnostic tests that help doctors evaluate the rate at which your stomach empties its contents. This can help them identify conditions that affect digestion, such as gastroparesis and pyloric stenosis. Gastric emptying studies are typically performed using a technique called scintigraphy, which involves ingesting a small amount of radioactive material and then tracking its movement through the digestive tract.

CPT Code for Gastric Emptying Study

The CPT code for a gastric emptying study is 78310. This code includes the following: * Ingestion of the radioactive material * Imaging of the stomach and intestines * Interpretation of the results

Indications for Gastric Emptying Study

A gastric emptying study may be indicated if you have symptoms such as: * Abdominal pain * Nausea * Vomiting * Bloating * Feeling full after eating a small amount of food * Weight loss

Procedure for Gastric Emptying Study

A gastric emptying study typically takes about 4 hours to complete. Heres what you can expect: * You will be asked to fast for 8 hours before the test. * You will be given a small amount of radioactive material to ingest. * You will lie down on a table under a gamma camera, which will track the movement of the radioactive material through your digestive tract. * You will be asked to eat a small meal, such as eggs and toast. * The gamma camera will continue to track the movement of the radioactive material for 4 hours.

Results of Gastric Emptying Study

The results of a gastric emptying study are typically reported as the half-emptying time (T1/2). The half-emptying time is the amount of time it takes for half of the radioactive material to empty from the stomach. Normal half-emptying time is less than 90 minutes. A delayed half-emptying time may indicate a condition that affects digestion, such as gastroparesis or pyloric stenosis.

Story Case 1:

A 55-year-old woman with a history of diabetes presented with complaints of nausea, vomiting, and abdominal pain. A gastric emptying study showed a delayed half-emptying time of 120 minutes, consistent with gastroparesis.

Story Case 2:

A 3-month-old infant presented with poor feeding and weight loss. A gastric emptying study showed a rapid half-emptying time of 45 minutes, consistent with pyloric stenosis.

Story Case 3:

A 25-year-old man with a history of anorexia nervosa presented with complaints of early satiety and weight loss. A gastric emptying study showed a normal half-emptying time of 75 minutes. This result helped rule out gastroparesis as a contributing factor to his symptoms.

Complications of Gastric Emptying Study

Gastric emptying studies are generally safe procedures. However, there is a small risk of radiation exposure. The amount of radiation exposure is very low and is not considered harmful.

Conclusion

Gastric emptying studies are important diagnostic tests that can help doctors evaluate the rate at which your stomach empties its contents. This can help them identify conditions that affect digestion, such as gastroparesis and pyloric stenosis. The CPT code for a gastric emptying study is 78310.
