What Q9961 covers
Q9961 identifies high-osmolar iodinated contrast material with an iodine concentration from 250 through 299 mg per mL. Radiology departments and other imaging providers use contrast agents during diagnostic studies to make selected organs, vessels, or other structures more visible on radiographic images. The route depends on the specific product and examination; the code identifies the contrast material by concentration, not the imaging procedure or the route of administration.
CMS assigns this HCPCS Level II code physician fee schedule status E, so it is excluded from the physician fee schedule. When Medicare covers the item, payment is under another method; the HCPCS pricing method classifies it as a Part B drug, generally paid using CMS quarterly Average Sales Price drug pricing files. Special Medicare coverage instructions apply. The billing unit is 1 mL, so report units based on the volume represented by the claim and document the product, iodine concentration, and amount used.
