Guaranteed issue rights--specifically NC

70F, no serious medical history (no cancers, nothing cardiac, normal blood pressure, non diabetic, etc).

I have had (and have been very happy with) an Advantage plan here in NC. That specific plan (let call it plan C) is being discontinued by my specific insurer. Does that give me "guaranteed issue rights"--even though there are other options from that specific Advantage plan group/insurer (plans A,B and D)?

I would like to use my guaranteed issue rights to change to a supplement. I can probably pass underwriting, but, of course prefer not to jump through a bunch of hoops if not necessary. I have talked to 2 different enrolled agents and got 2 different answers. So, I called the NC SHIPP--they basically said, "I don't know. I guess it wouldn't hurt to try."

Hopefully someone can answer this question in a somewhat timely manner.
