HCPCS Code Q9957: Injection, Perflutren Lipid Microspheres, per mL

No. Q9957 is a supply code tied to an echocardiography procedure. Bill it with the associated echo service in the office using CPT codes or with the appropriate C-code in the hospital setting. Many facility claims show packaged payment for the supply, but the drug should still be reported.

Bill the actual milliliters administered as whole units. If any whole-unit amount is discarded from a single-use vial, report that quantity on a separate line with the JW modifier. Do not round up partial milliliters unless your payer publishes instructions that permit rounding to the next unit.

Use the payer’s instructed alternative, which may be A9700 or an unlisted supply code with a clear narrative. Include the product name, total mL administered, and the related echo procedure. Contact the plan for written guidance to reduce denials.
