What Q9963 covers

Q9963 identifies high-osmolar contrast material with an iodine concentration of 350–399 mg per mL. Imaging departments and radiology practices report the contrast product furnished for diagnostic imaging; it is not the imaging examination or its interpretation. The concentration range distinguishes Q9963 from adjacent contrast codes. Each unit represents 1 mL of material.

CMS assigns Q9963 physician fee schedule status E, excluding it from the physician fee schedule. When Medicare covers the item, payment is made under another payment method. The HCPCS pricing method classifies it as a Part B drug, generally paid using CMS quarterly ASP drug pricing files. Special Medicare coverage instructions apply. Report units by the number of milliliters furnished, and select among related codes according to the material’s osmolar classification and iodine concentration.

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.

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.
