What 78264 covers

A nuclear medicine team administers a radiolabeled meal and obtains serial images to track its passage out of the stomach. The study is commonly ordered for patients with nausea, vomiting, early satiety, or post-meal fullness when delayed gastric emptying is being evaluated. A nuclear medicine physician interprets the images; a technologist typically prepares the imaging equipment and acquires the study in a hospital or outpatient imaging department.

Report 78264 for the gastric-emptying assessment itself, rather than an examination that also evaluates transit through the small bowel or colon. The record should identify the meal or protocol used, document image acquisition, and include the physician’s interpretation of gastric emptying. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and an unmodified claim represents the global service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

78264 billing questions

When should 78264 be chosen over 78265?

Use 78264 when the study assesses gastric emptying alone. Choose 78265 when the examination also evaluates small-bowel transit.

How should the professional and technical services be reported?

Append modifier 26 for the physician’s interpretation or modifier TC for the equipment and staff portion. Report the global service without either modifier.

What documentation supports this code?

Document the gastric-emptying protocol and meal, image acquisition, and the interpreting physician’s findings. The report should make clear that the examination evaluates stomach emptying rather than downstream transit.

Can this code be used when small-bowel or colon transit is also assessed?

Use the code that reflects the full study performed: 78265 includes small-bowel transit, and 78266 includes small-bowel and colon transit with gastric emptying.

Does 78264 represent a single image or the gastric-emptying examination?

It represents the gastric-emptying imaging study, which uses serial images to assess passage of the meal from the stomach.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
