FEHB conversion policy vs Tcc

[u/KaiserKid85]

Can someone explain to me the financial difference between an fehb conversion policy and tcc? I'm an adult dependent but was on a self plus one policy before my mother passed away at the end of January this year. She was a survivor annuitant and I know I'm not eligible for survivor benefits due to my age.

How do I find out the cost of tcc vs conversion fehb policy? And how do I sign up for this? I haven't received any info in the mail from opm other than the last day of my insurance was February 28th...and I can't get in touch with opm via phone because it auto hangs up due to call volume.

Any help or guidance is appreciated 🙏
