I'd add that it isn't over until it is over. When you get credit, what is happening in the investigation? If you stop doing anything and so do others connected with this, then it is over. But if you're still reviewing authorizations, photos, etc. than the claim is still ongoing and you don't want to call it to an end. When you send that letter, it is over. As John noted, you can't just sit on your hands though, watching the calendar.
