What A9548 covers

Indium-111 pentetate is a diagnostic radiopharmaceutical used in radionuclide cisternography and other cerebrospinal fluid studies, including investigation of suspected CSF leakage or altered flow. Nuclear medicine professionals use it as an imaging agent, typically administered intrathecally for these studies. A9548 identifies the radiopharmaceutical rather than the imaging procedure; CPT 78630 identifies cisternography.

A9548 is a HCPCS Level II code with physician fee schedule status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. In the HCPCS pricing file, its pricing method is payment set by statute; coverage is left to the Medicare contractor’s judgment. Each unit represents 0.5 millicurie of indium In-111 pentetate, so 1.0 millicurie corresponds to 2 units.
