Once Cuddy knew about the Detox, they went straight to his place. Why would they tell his team? House is not a fan of putting himself in vulnerable positions, and in previous episodes when his old team has seen him detox, he's played it off (Detox) or only let someone he trusted get close (Cameron), or only seen them because he didn't have much of a choice/used the case they brought him as a distraction (season 3 Tritter/rehab storyline). He didn't even trust Wilson to stay with him for this detox; I think if he had called his team now, it would have seemed musplaced and forced. "Goin 2 detox brb!"
