What 78708 covers
A renal renogram uses a radiotracer and serial imaging to assess blood flow, relative renal function, and tracer washout after a pharmacologic challenge. Common situations include evaluating suspected urinary obstruction with delayed drainage or assessing renal response to an ACE inhibitor, such as captopril. A nuclear medicine physician or radiologist interprets images acquired in a hospital or outpatient nuclear medicine department; technologists perform the imaging, and the drug challenge is part of the study.
Select this code when the renal flow-and-function imaging includes a pharmacologic intervention. Document the clinical indication, intervention, imaging performed, and interpretation. Use 78707 for the corresponding study without a drug intervention; 78709 describes studies involving multiple pharmacologic interventions. CMS allows the professional component with modifier 26, the technical component with modifier TC, or the global service without either modifier.
