EXCLUSIVEThe clinic where Joan Rivers suffered respiratory and cardiac arrest is now in the cross hairs of NY health officials -- TMZ has learned they're "reviewing" the case.
Sources tell us the state's Dept. of Health has contacted the clinic -- Yorkville Endoscopy -- twice since last Thursday ... when Rivers was getting an outpatient procedure to repair her vocal cords.
State health officials tell TMZ they are "reviewing the matter" ... but have NOT launched an official investigation. We're told the review could take weeks or even months. At this point, officials are only looking at the clinic as a whole -- not specifically the doctor who performed the procedure.
As we reported ... Rivers has been moved out of ICU and into a private room at Mount Sinai hospital. It's unclear whether she's still on life support.
