I'm 100% sure that yes there's two months SEP after a move. That's one thing. Another thing entirely is that once the carrier is notifed of a move, then they're required to term the plan at the end of that current month. That does not affect the SEP which is still the full two months following the move.
You would think that the two events (drop of plan coverage and sep for new) would coordinate.
I wonder if, in this situation, if uhc would give one extra month of coverage?
I guess the prospect at least has OM for one month, so it's not like she has nothing... but still.
