David West scored 29 points and Paul George had 21 points, 11 rebounds and five assists, leading Indiana past short-handed Chicago 111-101 on Monday night, and into a share of the Central Division lead.
The Pacers have won three straight and extended their home winning streak to 14, matching the team's longest since 2002-03.
Marco Belinelli had a season-high 24 points and Nate Robinson had 19 to lead the Bulls, who lost for only the third time in nine games. The Bulls played again without starting guards Kirk Hinrich (elbow), Derrick Rose (knee) and center Joakim Noah (foot). The Bulls also survived a scare when Marco Belinelli crashed to the floor clutching his right ankle late in the first quarter.
