I’ve been coding 93306 for a transthoracic echocardiogram, but now I’m being told that I should be coding C8929 instead when we use LUMASON® (sulfur hexafluoride lipid-type A microspheres) for injectable suspension. Which is correct?
CPT codes such as 93306 should be reported by non-hospital imaging centers and physician offices for echocardiography, whether or not ultrasound contrast agent is used during the exam. Hospitals billing under OPPS should report the 933xx CPT codes for non-contrast echocardiography, but must report HCPCS level II codes C8921 – C8930 for contrast echocardiography.
C8929 is the contrast echo code that is analogous to 93306
In addition to C8929 (or other appropriate C-code), you should also report Q9950 for the supply of LUMASON itself. This code solely applies to LUMASON and Q9950 is reported per mL. There are 5 mL’s in each Lumason vial.
C8929 Transthoracic echocardiography with contrast, or without contrast followed by with contrast, real-time with image documentation (2D),
Q9950 Injection, sulfur hexafluoride lipid microspheres, per mL
