HCPCS code C8929: Transthoracic echocardiography with contrast

No, you cannot report C8929 and a contrast agent Q-code separately for reimbursement under Medicare OPPS. The payment for C8929 already includes the contrast material when used, so the Q-code would be denied as bundled. Some commercial payers may allow separate reporting, but this depends on individual payer policy.

Generally, no. "C" codes are temporary codes created by Medicare specifically for hospital outpatient services under OPPS. Physicians' offices should typically use the corresponding CPT codes, such as 93306, and bill for the contrast agent with a separate "Q" code. It's always best to verify with the specific payer's guidelines.

Clinical records must note the justification for contrast (e.g., poor acoustic window), specify the contrast agent and volume, and confirm completion of all required imaging components: 2D, M-mode (if done), spectral Doppler, and color Doppler.
