What A9555 covers
Rubidium-82 is an intravenous radiotracer used for PET myocardial perfusion imaging to assess blood flow to the heart muscle. Nuclear medicine and cardiology teams commonly use it during cardiac evaluation at rest and with pharmacologic stress. A9555 identifies the radiopharmaceutical dose used with the imaging study, rather than the PET imaging service itself.
A9555 represents one study dose of rubidium-82, up to 60 millicuries. Its physician fee schedule status is C, meaning the Medicare Administrative Contractor sets payment for each claim; CMS publishes no national payment. The HCPCS file establishes no payment value, and coverage is left to the Medicare contractor’s judgment. This is a HCPCS Level II radiopharmaceutical code.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
