CPT code 78707: Renal imaging, single study, no drug2026 Medicare rate & RVUs

Medicare pays $209.42 for 78707 nationally in the office. Local office rates run $183.29–$288.84.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
