Carilion Clinic has seen its revenues increase and operating loss improve, even as the health system's net assets have continued on a steep and steady decline. The Roanoke-based nonprofit healthcare provider recorded an operating loss of $6.2 million on total revenues of $1.3 billion for the year that ended Sept. 30, according to its latest audited financial report. That's a stark improvement over the previous year, when Carilion posted an operating loss of $45.9 million on revenues of $1.2 billion, and it beat Carilion's internal projections, which budgeted for an $18.5 million operating loss, said Carilion Chief Financial Officer Don Lorton.
