text: No its not-most reputable insurance plans cover mental health and prescriptions  -sounds like he has a supplemental insurance plan and not  Major Medical which he needs to have-unfortunately even if he changes this is a preexisting condition and more than likely will have a waiting period to cover it.  He can get  prescription card now-search under prescription help and similar topics and can get one for approx 90 some dollars a year or even less . His family doctor can prescribe Zoloft-any MD can.Tell him to go for family doctor will understand his situation if he doesn't any MD will/can prescribe and then shop for lowest price like at Costco.  Hope I helped.
