HCPCS code A9571: Labeled platelets, per study dose2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for A9571 in California.

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

What A9571 covers

This code reports a diagnostic dose of the patient’s own platelets labeled with indium-111 for a nuclear medicine platelet study. The patient’s platelets are collected, labeled, and reinfused; nuclear medicine teams use the labeled cells to evaluate platelet survival or distribution. The product is distinct from radiopharmaceuticals made with labeled white or red blood cells because it contains autologous platelets.

A9571 identifies the radiopharmaceutical dose rather than the scan or its interpretation. One unit represents one study dose, not a milligram amount. Medicare assigns physician fee schedule status C: there is no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for each claim under other contractor pricing. Coverage is left to the contractor’s judgment.

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.
