Narrative:
We were in level flight at 23000'. West/O receiving a primary target or a TA first, we got an RA at 10:30, 10 mi. The target information was 900' climbing. We did not see the traffic visually and performed the TCAS maneuver, which brought us to 23800' before 'clear of conflict.' we advised ATC and descended back to 23000'. ATC later told us that the traffic had been climbing to 22000'. Interpretation: RA not necessary.
