What does CIGNA consider as “on-site” supervision for “incident to” services?
Per CMS Publication 100-, the Medicare Claims Processing Manual, Chapter 15 , Section 60.1, Subsection B, the physician must be present in the office suite and immediately available to provide assistance and direction throughout the time the auxiliary personnel is performing services. CIGNA Government Services would interpret this as in the same office suite which should furthermore be the same floor/building.
