RCC Contrast Media, Supplies & HCPCS Level II Coding 1

Question 1

Which type of iodinated contrast media is associated with a lower risk of adverse reactions due to its osmolality being closer to that of blood?

Accepted Answer

Low-osmolality contrast media (LOCM)

Answer

Low-osmolality contrast media (LOCM) has osmolality closer to blood plasma and is associated with significantly fewer adverse reactions than high-osmolality ionic contrast media.

Question 2

When a CT scan is performed both without and with contrast, what is the correct CPT coding approach when a dedicated combination code exists?

Accepted Answer

Use the single CPT code specifying 'without contrast followed by re-imaging with contrast'

Answer

CPT provides dedicated combination codes (e.g., 74178 for CT abdomen/pelvis without and with contrast) that must be used instead of unbundling into two separate procedure codes.

Question 3

Which HCPCS Level II code category covers most low-osmolality iodinated contrast agents used for intravascular injection?

Accepted Answer

Q codes (Temporary Codes)

Answer

Low-osmolality iodinated contrast agents are reported using Q-codes (temporary HCPCS codes such as Q9965-Q9967), which specify iodine concentration range and are billed per ml administered.

Question 4

Gadolinium-based contrast agents used in MRI are primarily reported using which HCPCS code series?

Accepted Answer

A9576-A9579 (gadolinium-based MRI contrast agents)

Answer

Gadolinium-based MRI contrast agents are reported with HCPCS A-codes: A9576 (gadopentetate dimeglumine), A9577 (gadobenate dimeglumine), A9578 (gadoxetate disodium), and A9579 (NOS).

Question 5

A facility administers contrast media intravenously during a CT scan. Which separate CPT code should be reported for the IV injection of the contrast agent?

Accepted Answer

No additional injection code; contrast administration is bundled into the imaging CPT

Answer

Contrast administration (injection) is considered integral to the radiology procedure and is included in the imaging CPT code; it should not be reported separately.
