Due to the 1993 Copa América, a minor tournament (1993 Torneo Intermedio) was played in the middle of the year between the 16 clubs. The winner would qualify for the 1994 Copa CONMEBOL.
The end-of-season Liguilla would feature 4 teams, instead of 6.
A preliminary round prior to the Liguilla would be played with the teams that placed 3 to 8 to determine the 3 teams that join the second-placed team in the Liguilla.
The third-to-last team in the Torneo Descentralizado plays a relegation playoff against Copa Perú runner-up.
Alianza Lima started the Liguilla with a bonus point. Alianza Lima and Sporting Cristal tied for first placed, forcing a playoff match to determine the second Peruvian club in the 1994 Copa Libertadores. Although Sporting Cristal lost the playoff match, they qualified for the 1994 Copa CONMEBOL after Deportivo Municipal declined to play in it.
