Narrative:
We were level at 22000 awaiting higher altitude. TCAS announced 'traffic'. Scope depicted traffic 11 O'clock, 600 ft below, and climbing. Traffic continued to close and climb. The captain initiated a level turn to the right and the target passed off the left at our altitude and approximately 1 mi. No visual contact was made. Geneva center was advised and they acknowledged that an aircraft had just appeared on the scope in our vicinity. Center advised that they were contacting milan center regarding the traffic.
