Help! We have 6 locations, but only 1 lab. CLIA number is associated with lab location. We have always billed out pathology based on location the sample was taken, not the location where the sample is analyzed. We now have UHC claims denying stating the address submitted is invalid or missing. We haven't had any issues with any other insurances (including Medicare) but our UHC rep has been very unhelpful. Can someone please shed some insight?
