charge off...chapt 13

our second mortgage was charged off after being more than 180 days late and while we were in chapter 13. when our chapter 13 was discharged it was stated in our credit report that the second mortgage had been included in our chapter 13 and was discharged also. it was in the amount of 89000.00 the status of our discharge is oct. 03, 2012 does this mean we dont owe this debt anymore? the second mortgage was with citibank :confused:
