Due to Chile's qualification to the 2010 FIFA World Cup, the format for the season had seen a minor modification in the Apertura, which would not have the playoff stage.
The next best-placed team played a playoff against Municipal Iquique for the last berth in the 2010 Copa Sudamericana.
The season champion (the team with the most points after all 34 dates) also earned a berth to the 2011 Copa Libertadores.
The Chile 3 berth for that competition have gone to the winner of a Liguilla of the 2nd, 3rd, 4th, and 5th best-placed teams at the end of the season.
Universidad de Chile, Audax Italiano, Unión Española and Huachipato qualified for the Copa Libertadores Liguilla.
