What A9578 covers
A9578 identifies gadobenate dimeglumine, a gadolinium-based contrast agent administered intravenously to enhance MRI images. Radiology departments use it for MRI examinations of the central nervous system and for magnetic resonance angiography. The code distinguishes the MultiHance multipack presentation from the separately identified non-multipack presentation; it does not describe the imaging service itself.
The physician fee schedule status is X, a statutory exclusion, so the physician fee schedule does not pay this item. When covered, Medicare treats it as a Part B drug generally priced through CMS's quarterly Average Sales Price files and pays it under another fee schedule or payment system. Coverage is left to the Medicare contractor's judgment. Each unit represents 1 mL; report units according to the volume administered, not the number of multipacks.

A9578 billing questions
How does A9578 differ from A9577?
Both identify gadobenate dimeglumine, but A9578 is for the multipack presentation. A9577 identifies the drug without that multipack designation.
Does one unit represent one multipack?
No. One unit represents 1 mL; units follow the volume administered, not the package count.
Does the physician fee schedule pay A9578?
No. Its status X is a statutory exclusion from physician fee schedule payment. When covered, it is generally priced as a Part B drug through CMS quarterly ASP files.
Who decides whether Medicare covers A9578?
The Medicare contractor makes the coverage determination. Coverage is left to contractor judgment.
Which contrast agent code applies when the product is known?
Use the code identifying the specific drug and presentation, such as A9578 for gadobenate dimeglumine multipack. A9579 is for gadolinium-based MR contrast when the agent is not otherwise specified.
