We took off from ZZZ.  We made a right turn to 250 heading; then were cleared to climb to 5;000 ft.; and then turn to 190 heading. While cruising at 5;000 ft.; we had just crossed the northern surface-12;500 ft Bravo line of ZZZ1 when we approached what looked like an aircraft about 500 ft. higher heading directly toward us.  As we got closer the object looked more stationary and appeared to be a drone.  We let ATC know it was a possible drone and answered a few questions from them and continued on our way.  The remainder of the flight was uneventful.Always maintain a good visual lookout; even in Class B airspace.
PC-12 Captain reported an airborne conflict event during cruise with a Drone; no significant conflict. Reported event to ATC.
