Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What A9526 covers

Nitrogen-13 ammonia is a radioactive imaging agent administered intravenously for PET assessment of myocardial perfusion. Nuclear medicine and cardiac imaging teams use it in cardiac PET studies, including protocols that assess blood flow at rest or with stress. The tracer identifies the radiopharmaceutical supplied for the study; the PET acquisition and interpretation are represented by the applicable imaging service code.

A9526 represents one study dose of up to 40 millicuries, rather than a unit for each millicurie. Its physician fee schedule status is carrier priced: CMS publishes no national payment amount, 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 Medicare contractor’s judgment.
