The POS file consists of two data files, one for CLIA labs and one for 18 other provider types. The file names are CLIA and OTHER. If downloading the file, note it is fairly large (125MB in CSV).
The POS Extract is created from the QIES (Quality Improvement Evaluation System) database. These data include provider number, name, and address and characterize the participating institutional providers. The data are collected through the Centers for Medicare & Medicaid Services (CMS) Regional Offices. The file contains an individual record for each Medicare-approved provider and is updated quarterly. For a list of provider types, layout files, and how to order previous annual files, please see the Source Link in the About tab.
Two data issues in the CLIA POS file have been resolved as of the 2nd Quarter 2016 file. The data issues occurred in CLIA POS files starting with the 2nd Quarter 2011 file through 1st quarter 2016.
Data Issue 1: Incorrect Certificate Data
Certificate data in the CLIA POS file should always come from the lab's current effective certificate. Due to a sorting issue, certificate data from a lab's pending or historical certificates were used and the lab's current effective certificate data was not used.
