HCPCS code A9552: FDG, per study dose2026 Medicare rate & RVUs

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

What A9552 covers

Fluorine-18 fluorodeoxyglucose (FDG) is an intravenously administered radiopharmaceutical used to trace glucose metabolism during PET imaging. It is commonly used in oncologic evaluation and also in selected cardiac and neurologic studies. Nuclear medicine departments, hospital imaging services, and independent PET centers typically report the radiopharmaceutical supply when administering FDG for a diagnostic study; the PET acquisition is a separate service.

A9552 represents one study dose containing up to 45 millicuries, not a unit for each millicurie. Its physician fee schedule status is C: CMS publishes no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for the claim. The HCPCS pricing method identifies payment as set by statute. CMS leaves coverage to the Medicare contractor’s judgment, so the code alone does not establish coverage for a particular indication.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
