What A9557 covers

Technetium-99m bicisate is an intravenously administered imaging agent used for cerebral perfusion imaging, most commonly with SPECT. Nuclear medicine teams use it to show patterns of blood flow in the brain during evaluations such as suspected stroke, seizures, or cognitive disorders. The radiopharmaceutical is administered before image acquisition; the imaging service itself is distinct from the supplied dose.

Medicare assigns this code physician fee schedule status C, or carrier priced: CMS publishes no national payment, and the Medicare contractor sets payment for each claim. The HCPCS pricing method is other contractor pricing, and coverage is left to the contractor’s judgment. One unit represents a diagnostic study dose up to 25 millicuries, not a per-millicurie amount.
