Nuclear medicine
About 78707: Renal flow and function imaging without intervention
Reports a single radionuclide kidney study that evaluates blood flow and renal function without a pharmacologic intervention such as a challenge drug.
This nuclear medicine study tracks a radiopharmaceutical through the kidneys to assess renal perfusion and function, including how each kidney takes up and processes the tracer. It is typically performed in a hospital or outpatient imaging department by nuclear medicine technologists, with a physician interpreting the images. Common clinical questions include impaired renal function or suspected urinary obstruction when the study is performed without a pharmacologic challenge.
Select this code when the documented protocol is one flow-and-function study without pharmacologic intervention; use a different code when the protocol includes a drug or multiple studies. The record should support the imaging protocol, tracer administration, image findings, and physician interpretation. CMS recognizes professional and technical components: modifier 26 reports the interpretation, modifier TC reports equipment and staff, and billing without either modifier represents the global service.
CMS billing rules for 78707
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

78707 billing questions
How does this differ from 78708?
78707 describes a single renal flow-and-function study without pharmacologic intervention. Use 78708 when the study includes a pharmacologic intervention.
When is 78709 a better fit?
Use 78709 when the documented protocol involves multiple studies. A single study without pharmacologic intervention fits 78707.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the physician interpretation, and modifier TC identifies the technical service; without either modifier, the claim represents the global service.
What documentation supports reporting 78707?
Document the renal flow-and-function imaging protocol, that it was a single study without pharmacologic intervention, and the imaging findings and interpretation.
Is this the same as a kidney morphology study?
No. 78707 evaluates renal flow and function. Code 78700 is for kidney imaging focused on morphology.
