Charging for a FFR computation for CTA done at another site

Q.

If a separate entity sends data to my site of a previously performed coronary CTA and then, at my site, we take this data and derive the Fractional Flow Reserve (FFR), can we charge for the calculation of the FFR?

A.

Yes, you can submit Category III CPT^® code 0503T. This code does not include performing the original CTA. This FFR computation is done on a previously obtained coronary CTA.

The code and full description are:

0503T Noninvasive estimated coronary fractional flow reserve (FFR) derived from coronary computed tomography angiography data using computation fluid dynamics physiologic simulation software analysis of functional data to assess the severity of coronary artery disease; analysis of fluid dynamics and simulated maximal coronary hyperemia, and generation of estimated FFR model
