What A9579 covers

This HCPCS Level II code identifies a gadolinium-based contrast agent for MRI when the administered product is not represented by a more specific code. These agents are administered intravenously to improve visualization on MRI. Radiology departments, imaging centers, and other facilities furnishing the contrast may report the drug item with the MRI service.

Medicare assigns status X, meaning the physician fee schedule does not pay this code because it is not a physician service under the Medicare statute. When covered, it is treated as a Part B drug and generally paid using CMS quarterly Average Sales Price drug pricing files. Coverage is left to the Medicare contractor’s judgment. One billing unit represents 1 mL; report units according to the volume furnished. Use a product-specific code when the administered agent has a more specific HCPCS code.

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.

A9579 billing questions

When should this code be used instead of a product-specific gadolinium code?

Use this code when the gadolinium-based MRI agent is not represented by a more specific HCPCS code. If the administered product has its own code, report that product-specific code instead.

How many units should be reported?

Each unit represents 1 mL. Report units according to the volume of the agent billed.

Does Medicare pay this code under the physician fee schedule?

No. Status X means the physician fee schedule does not pay the code; when covered, it is treated as a Part B drug and generally uses CMS quarterly ASP drug pricing files.

Does Medicare automatically cover the contrast agent?

No. Coverage is left to the Medicare contractor’s judgment.

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.
