I am not sure how long my medcadi is good for.calling the aid office always causes me stress.one the local office never answers the phone.2 I had them call me back a month after I left them a voice mail.but I missed the phone call while I was sleeping.Their toll free number told me my medcadi is good until December but last year the same people told me the same thing but the information was wrong.i at times get a medcadi application in March or April.But several times I did not get the medicadi application in the mail.i could call the local office for hours & days with no response.even the local office gave me the wrong information a few times last year.i have to go through this every year.i live in the state of Illinois & the aid office is in a dangerous ghetto.they are never helpful.i stress over this every time.i hate calling them,going to their office etc.this is not helping my depression one bit
