One more comment from someone who's done it:

ditto on everything Philly said; log who/when you talk to. DON'T believe what 1800-tri... tells you, not sure where they find these people, but they'll tell you anything to get you off the phone!!

As explained to me, TriCare's system can't forecast your status (only looks at "TODAY" in DEERS). So you HAVE to fill out ppwork once your status changes. One other note to look forward to, if you go on orders for 30+ days, you qualify for Tricare Prime again, but make sure your status changes don't outrun your paperwork. They say that causes HUGE problems, ie:

Good: status change1 > paper work1 > status change2 > paperwork2
NOT: status change1 > status change2 > ppwk1 > ppwk2, etc.

Also, I went from TRS back to Prime because I went back on orders, so get this: My whole family was on Prime with TRS, but when I re-signed them up to Prime via my contingency orders, they had to wait until the following 1st of month, ie: resulting break in coverage...not good for wife+2yr+9mo.

I'd print out 50 adressed envelopes to your congressman and just keep writing.
