What A9570 covers
This radiopharmaceutical is prepared by labeling a patient’s own white blood cells with indium-111 and reinjecting them for diagnostic imaging. Nuclear medicine departments use the study to help locate infection or inflammation, such as a suspected abscess or osteomyelitis. The dose is patient-specific because it uses the patient’s cells; the imaging service is performed and reported by the nuclear medicine provider or facility.
A9570 identifies the indium-111 labeled cell dose, not the imaging procedure. Medicare assigns physician fee schedule status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. HCPCS pricing uses other contractor pricing, and coverage is left to the contractor’s judgment. The code is defined per study dose; one billing unit represents one study dose, rather than a measure of radioactive activity.

A9570 billing questions
When should A9570 be used instead of A9569?
A9570 identifies autologous white blood cells labeled with indium-111. A9569 identifies autologous white blood cells labeled with technetium-99m; use the code matching the radiopharmaceutical administered.
How many units should be reported?
The code is per study dose, so one billing unit represents one study dose. Do not calculate units from the dose’s millicurie activity.
Does A9570 describe the scan itself?
No. It identifies the indium-111 labeled white blood cell dose. The imaging procedure has its own code, selected to reflect the imaging performed.
How does Medicare set payment and coverage?
A9570 has physician fee schedule status C, so CMS publishes no national payment and the Medicare Administrative Contractor sets payment for each claim. Coverage is left to the contractor’s judgment.
How does A9570 differ from A9571?
A9570 is for indium-111 labeled autologous white blood cells; A9571 is for indium-111 labeled autologous platelets. Select the code for the labeled blood component used.
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.
