CPT code 74240: Upper GI series, single contrast2026 Medicare rate & RVUs in California

Medicare pays $130.62–$165.64 for 74240 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 74240 covers

This study follows swallowed contrast through the esophagus, stomach, and duodenum using fluoroscopy and radiographic images. A radiologic technologist typically performs the imaging in a hospital radiology department or outpatient imaging center, while a radiologist interprets the findings. It may be ordered to evaluate upper digestive tract symptoms or suspected structural abnormalities; the service is defined by the single-contrast technique, commonly using barium.

Report 74240 when the examination covers the upper GI tract using a single-contrast approach, rather than a double-contrast study or an examination limited to the esophagus. Documentation should identify the clinical indication, the areas examined, the contrast technique, and the interpreting physician’s findings. The global service includes the technical work and professional interpretation. If those portions are billed separately, use modifier 26 for the interpretation or TC for the equipment and staff portion.
