After Palmetto's MolDx released a final local coverage determination that panels of 3-5 pathogens will be covered, but larger panels will not be, Piper Jaffray analyst William Quirk said he believes 51% of the population is covered by MACs that follow MolDX. In terms of the decision's implications for Luminex, Quirk said he sees $3M-$4M in exposure to MolDx Medicare for Luminex's xTAG and Nanosphere tests. He also noted that Luminex management has talked about unbundling to make their panels smaller, which he believes will be the likely outcome. Quirk has a Neutral rating on Luminex shares.
