What 78700 covers

This nuclear medicine study produces images of the kidneys’ location, size, contour, and cortical pattern after administration of a radiopharmaceutical. It may be used when evaluation centers on renal anatomy or suspected cortical abnormalities, such as scarring. A nuclear medicine technologist typically acquires the images in an imaging department, and a physician interprets the study.

Choose 78700 when the performed study evaluates renal morphology, rather than renal blood flow or function. The record should support the clinical reason for imaging, the study performed, and the physician’s interpretation. CMS recognizes separately priced professional and technical components: the interpreting physician may report modifier 26, the equipment-and-staff portion may be reported with modifier TC, and billing without either modifier 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.

78700 billing questions

When should 78700 be chosen instead of 78701?

Use 78700 for a study focused on renal morphology. Use 78701 when the imaging protocol includes assessment of renal blood flow.

How does 78700 differ from 78707 or 78708?

Those codes describe renal imaging that evaluates flow and function. Code 78700 is for morphology-focused imaging.

Which modifiers identify the professional and technical portions?

Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Reporting the code without either modifier represents the global service.

What documentation supports reporting 78700?

Document the clinical indication, the morphology-focused imaging performed, and the interpreting physician’s findings. The record should distinguish the study from a renal flow or function protocol.

Can 78700 be reported for a renal function study?

Not when the performed study is a function study rather than morphology imaging. Consider the renal function code that matches the actual protocol, such as 78725.

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.
