What 78707 covers
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.

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.
