The Cavaliers say Mozgov had the procedure Wednesday at the Cleveland Clinic Marymount Surgicenter.
Late last month, the team picked up the $5 million option on his contract for next season.
The 7-foot-1 center was acquired in a January trade from Denver in exchange for two first-round draft picks.
Mozgov transformed the Cavs on defense, giving them a rim-protecting big man after Anderson Varejao was lost for the season.
Mozgov, who will turn 29 in mid-July, averaged a career-high 10.6 points and 6.9 rebounds in 45 regular-season starts. He became a needed offensive option during the postseason, averaging 10.6 points and 7.3 rebounds in 20 postseason starts.\
