Rainy,
How much notice did you get for these guys coming in? Under most circumstances I believe you have 30 days to reply or prepare. They don't have the right (not yet, until the CHITT portal goes into effect) to just drop in on you unannounced and have immediate access.
But PLEASE, protect yourself and do exactly as ROY suggests. Get your malpractice lawyer between you and whoever so you don't speak out of turn or give them extra stuff that they are NOT entitled too, that can then be used against you. Roy is very wise in a number of matters and this is certainly one of them. PROTECT YOURSELF!!!
And with that said, try and make up some excuse to delay these guys a few days until you have retained counsel and have had a chance to discuss the details with them. By going with your malpractice carrier's lawyers this should cost you close to nothing at least in the begining. They (your MP folks) have a vested interest in keeping you clean and safe too so they almost always will pay to advice and represent you in these instances and you should try your best to insist that they do. If as things progress (hopefully not) if you feel there is a parting in the ways of representing you properly (like settling too easily where you know you are innocent and want to see it thru) and fully then you can hire your own councel at your expense to make sure you are being defended vigerously and sincerely.
So get off the board right now and get to work defending your butt so we don't have to worry about you...Go, go, now!!!
Good Luck,
Paul
