HCPCS C9176: Tc-99m from Domestic Non-HEU Mo-99, Add-On Per Dose

HCPCS Level II code C9176 describes a per-study-dose add-on payment for technetium-99m (Tc-99m) produced using domestically sourced non‑HEU molybdenum‑99 with at least 50% domestic content; the service represents an isotope supply add-on tied to nuclear medicine radiopharmaceutical preparation and delivery, typically billed when a radiology or nuclear medicine department supplies the radiotracer for diagnostic imaging studies performed in hospital outpatient departments or ambulatory imaging centers.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult undergoing a diagnostic nuclear medicine study requiring technetium-99m (Tc-99m) radiopharmaceutical labeled material. The facility has procured Tc-99m produced from domestically sourced, non-HEU molybdenum-99 (Mo-99) and bills an add-on charge for full cost recovery per study dose under C9176. The patient is referred from outpatient nuclear medicine, cardiology, oncology, or orthopedics for imaging such as bone scan, renal scan, hepatobiliary study, or myocardial perfusion imaging.

Workflow:

Patient scheduled at an outpatient imaging center or hospital nuclear medicine department.
Radiopharmacy verifies availability of domestically produced non-HEU Mo-99–derived Tc-99m and prepares the study dose per routine sterile compounding and radiolabeling protocols.
Patient arrives, identity and indications are confirmed; intravenous access or oral/voiding instructions are performed as appropriate for the specific scan.
Radiopharmacist documents lot numbers, activity, and C9176 is added to billing as the per study dose add-on for the higher-cost domestically derived Tc-99m.
Nuclear medicine technologist administers the Tc-99m radiopharmaceutical; imaging is performed per protocol (timing, camera acquisition, SPECT/SPECT-CT or planar as indicated).
Images are interpreted by a nuclear medicine physician or radiologist; results documented and reported to the referring clinician.

Typical site of service: outpatient imaging center, hospital outpatient department, or inpatient nuclear medicine unit. Typical patient scenario: adult referred for a Tc-99m bone scan to evaluate focal bone pain and suspected metastatic disease, where the facility uses domestically produced non-HEU Mo-99–derived Tc-99m and bills C9176 per study dose as a full cost recovery add-on.

`78803`	Bone imaging, whole body; single or multiple areas (planar)	Commonly performed using `Tc-99m` radiopharmaceuticals; the `C9176` add-on would apply per study dose when domestically produced non-HEU Mo-99–derived `Tc-99m` is used.
`78801`	Radionuclide imaging, limited area (e.g., spot views), planar	Used for smaller or focused bone or other organ imaging studies that may use `Tc-99m` doses billed with `C9176`.
`78452`	Myocardial perfusion imaging, single study, planar or SPECT; including pharmacologic stress when performed	`Tc-99m` radiopharmaceuticals are commonly used for myocardial perfusion studies; `C9176` may be billed per injected dose.
`78700`	Hepatobiliary imaging (HIDA), includes radiopharmaceutical	HIDA studies utilize `Tc-99m` agents and are performed with a per-study dose that may incur the `C9176` add-on.
`78706`	Renal imaging, including qualitative and quantitative studies	Renal scintigraphy employs `Tc-99m` agents; `C9176` is related as the radiopharmaceutical cost add-on per study dose.
