Question: Maine Subscriber Answer: On May 2, CMS issued Transmittal 87, which revises the incident-to guidelines. The main revisions involve CMS' inclusion of nonphysician practitioners in much of the language. For instance, where the policy previously referred to a "physician's services," it now notes that it refers to a "physician's/NPP's professional services." You can find the new incident-to regulations on the CMS Web site at http://www.cms.hhs.gov/transmittals/downloads/R87BP.pdf.
