I had a post asking about how to properly code a pre-op exam (clearance) from a pcp provider, and it seems that you code the surgical CPT code with a modifer 56. What do you do if the surgeon is requesting labs and an EKG to be done? As the PCP, are we to be doing those tests in the office, or does the patient need to go to an outside lab or hospital lab as the surgeon being the ordering doctor. IF the PCP provider is suppose to do the EKG along with any labs... are these charges all included in the global fee of the surgery, or will there be the surgery code along with the certain labs and EKG fees? If I can get some guidance, that would be great; thank you !!
