What 78701 covers
This nuclear medicine study captures images of the kidneys’ morphology along with the passage of radiotracer through the renal blood supply. A technologist performs the acquisition using nuclear imaging equipment, and a radiologist or nuclear medicine physician interprets the images. It may be selected when the requested study needs to show both renal structure and perfusion, rather than kidney morphology alone or a renal flow-and-function study.
Report 78701 when the documented examination includes the morphology and vascular-flow elements. The order and imaging report should support that scope; do not select it solely because a kidney study was performed. CMS prices the professional interpretation and technical acquisition separately when reported with modifier 26 or TC, respectively. Reporting the code without either modifier represents the global service, including both components.

How to choose
- 78700Kidney imagingMorphology only
- Use 78700 for renal morphology imaging without vascular-flow images. 78701 includes the vascular-flow element.
- 78707Renal imagingSingle study, no drug
- 78707 is a renal flow-and-function study without pharmacologic intervention; 78701 reports morphology imaging with vascular flow.
- 78708Renal imagingPharmacologic intervention
- 78708 is a renal flow-and-function study with pharmacologic intervention. Select 78701 when the performed study is morphology imaging with vascular flow instead.
78701 billing questions
How does 78701 differ from 78700?
78701 includes vascular-flow imaging with kidney morphology. Use 78700 for renal morphology imaging without the vascular-flow element.
When should 78701 be chosen over 78707?
Choose 78701 for a morphology study that includes vascular flow. 78707 describes a renal flow-and-function study performed without pharmacologic intervention.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the code represents the global service.
What documentation supports reporting 78701?
The order and report should identify a kidney morphology examination with vascular-flow imaging. The report should make clear that the study included both elements.
Does 78701 describe a renal function study?
It describes kidney morphology imaging with vascular flow. A flow-and-function study is represented by a different renal imaging code, selected according to the study performed.
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.
