Ask Dr. Z

I recently started billing graphics again after many years. Since I last coded them I see they have added the option of a -26 modifier on code 93351. I would like to know if code 93351-26 includes the tracing (93017). My physicians do not do the tracing, so I thought I should be using codes 93350-26, 93016, and 93018. However, in a past question here, the answer stated that code 93351-26 includes codes 93350, 93016, and 93018 with no mention of 93017. In the CPT Codebook it says when all professional services of a stress test are not performed by the same physician to use code 93350 with the appropriate codes (93016-93018) for the components that are provided. Since my physicians do not perform the tracing, this sounds to me like I should be using codes 93350, 93016, and 93018 instead of 93351-26. Thoughts?
