HCPCS code A9576: ProHance injection, per 1 mL2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for A9576 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 A9576 covers

A9576 identifies ProHance, an intravenous gadoteridol contrast agent used to enhance MRI images, particularly for imaging the brain, spine, and surrounding central nervous system tissues. Radiology practices and imaging facilities report the drug when they furnish it for an MRI. The multipack designation identifies the product presentation, while the HCPCS unit is based on volume administered.

Medicare assigns A9576 statutory-exclusion status X: it is not paid under the physician fee schedule because it is not a physician service under the Medicare statute. When covered, it is treated as a Part B drug and is generally paid using CMS’s quarterly Average Sales Price drug pricing files; the Medicare contractor determines coverage. Report one unit for each 1 mL of gadoteridol administered, supported by the medication record.
