HCPCS code A9562: Mertiatide, per study dose2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for A9562 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 A9562 covers

Technetium-99m mertiatide, also known as MAG3, is a radiopharmaceutical administered intravenously for nuclear medicine imaging of the kidneys. Nuclear medicine clinicians use the resulting images to assess renal blood flow, kidney function, and tracer drainage into the urinary tract, including when evaluating possible obstruction. Imaging may include a diuretic intervention when clinically indicated.

A9562 identifies the diagnostic radiopharmaceutical, not the renal imaging procedure. Its unit represents one study dose of up to 15 millicuries. Medicare physician fee schedule status C means there is no national physician fee schedule payment; the Medicare Administrative Contractor sets payment for each claim. HCPCS pricing likewise assigns payment to the contractor, and coverage is left to that contractor’s judgment. The related renal imaging procedure is reported with its applicable CPT code.
