# CMS POS-CLIA Clinical Laboratory Roster

`vlada_curated.dim_clia_lab` · Provider identity · status live

CMS Provider of Services File — Clinical Laboratories (POS-CLIA): the quarterly roster of every CLIA-certified clinical laboratory in the US, published by CMS on data.cms.gov. ~103 source columns reduced to the roster spine — CLIA number, facility name(s), city/state/ZIP, composed 5-digit county FIPS, Medicare/CCN-style number, active flag (from the termination code), and the ownership/facility/certificate/lab-class category codes. Identifies and locates the lab side of diagnostic care (county join + a possible CCN bridge via CLIA_MDCR_NUM). Refreshed each quarter; the runner discovers the current CSV from data.cms.gov's data.json so it always pulls the latest quarter.

**Grain.** One row per certified CLIA laboratory (by CLIA number) per quarterly POS snapshot.
