24CLABQ2—the April 2024 Clinical Laboratory Fee Schedule (CLFS) files
The official CMS data behind Q2 2024 on this site—in effect April 1 – June 30, 2024. The quarterly lab fee schedule files (26CLABQ3, 25CLABQ4, …) carrying what Medicare allows for every clinical laboratory test it prices nationally—finished dollar amounts rather than RVUs—plus the rows CMS flags for MAC pricing instead.

Files without a download link carry a descriptor column that isn't licensed for redistribution and couldn't be safely removed automatically. Their columns are documented below all the same, and CMS's own copy is one click up.
What the columns mean Copy link
CMS ships these files with minimal documentation, and both the column names and their order drift between releases—which is why we parse by header name, never by position. Any column position shown here is the one we recorded when parsing this release.
