Water change would be a good idea,a damaged anem can release alot of mucus which can be very harmfull to the rest of your corals.Has it backed out enough to see how badly its damaged? I would have to think most of the tenticles are lost,but if the oral disc and foot are OK it should repair itself if it was in good health to begin with,barring an infection.No matter how much or little damage is done,when you can,get it into an area with decent flow,enough to wash around the damaged areas to keep it clean from debris.
