At XA:00Z the Salt Lake Approach; Stockton Controller; called me on the shout line to approach request Aircraft X direct to MLF at 12;000.  I approved this move knowing that the approach controller usually keeps the departure aircraft at least semi-near to FFU and V21 to miss the higher terrain to the west.  In this case they did not; and the aircraft began approaching an area where the MIA's are 13;000. Coordinate even further to make sure that the aircraft will stay clear of the terrain.  If there are any questions always clarify.
Center Controller reported poor coordination leading to an aircraft flying towards a higher MIA; Minimum IFR Altitude.
