Compliance Question of the Week – Cardiology

I have another question about moderate sedation code assignments. The descriptions of codes 99151–99153 indicate 15 minutes of service time. What if there is less than 15 minutes? Can this be billed?

As a follow-up to last week’s question, what codes would be reported for moderate sedation used with TEE?

Do the changes to the moderate sedation guidelines mean that my doctor can now bill for this when he provides it during a transesophageal echocardiogram (TEE)?

We were told we should bill code 96374 for administration of LUMASON® (sulfur hexafluoride lipid-type A microspheres) for injectable suspension, for intravenous use or intravesical use with echocardiogram with contrast, but we are getting denials for this code. Is there another code we should use?

If non-selective renal angiography is performed at the time of a dagnostic cardiac catheterization, should level ll HCPCS code G0275 be reported? Is this code for hospitals or physician billing? Is this code for Medicare or non-Medicare patients?

What is the intent of code 93463?
