Has anyone heard of a physician office lab (POL) that takes specimens in from other non-affiliated referring physicians? Basically, can a physician office lab that is owned by a large GI group receive specimens from a GI doc that is not part of the group and bill for it under the large GI group's tax ID? In other words can a POL act as an independent clinical lab or a reference lab and do work that originates outside it's group? Intuitively one would think that if you are designated as a POL by CLIA that you work should be limited to your own group's work. One could also make the argument that you are not violating any Stark laws granted the referring lab or provider does not have a financial interest in your group (or is not getting a kickback). I am having trouble finding an answer to this. What do you think?
