Carriers can no longer reject claims for not checking Box 20

Article Overview

This article covers a CMS transmittal that changed how carriers should process claims when Box 20 on the CMS-1500 is incomplete for diagnostic services involving outside laboratories or purchased technical components. It is relevant to physicians, coders, billers, and practice managers who submit Medicare claims for imaging and other diagnostic services, because it addresses claim acceptance, reporting expectations, and the risk of payment inaccuracies when outside services are involved.
