What A9551 covers
Technetium-99m succimer, also called DMSA, is a radioactive diagnostic agent used to image the renal cortex. Nuclear medicine departments use it for studies that assess cortical defects, including suspected renal scarring. The radiopharmaceutical is administered intravenously, and the imaging service is reported separately from the agent. Nuclear medicine and radiology practices typically report the drug code when furnishing the study dose.
On the physician fee schedule, status C means CMS publishes no national payment and the Medicare Administrative Contractor sets payment for each claim. The HCPCS pricing method is payment set by statute, and coverage is left to the contractor’s judgment. One unit represents a study dose containing up to 10 millicuries; the code identifies the agent, not the renal imaging procedure.
