CMS has posted its preliminary payment determinations for new 2015 clinical laboratory fee schedule codes. The document lists CMS’s recommendation regarding the basis of payment for codes -- either crosswalk or gap-fill. Note that CMS is recommending to delay pricing various individual drug testing screening codes given “the potential for overpayment when billing for each individual drug test rather than a single code that pays the same regardless of the number of drugs that are being tested for.” Additional information about the comment and reconsideration process is available on the CMS website.
