HCPCS code A9570: Indium-111 WBC, 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 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.

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.
