Hmm. Well, you might want to change your subject line to something like "hysto while legally male." (Not very grammatical, but it gets the point across.)
Does your insurance cover trans-related hysto? If so, you might be able to get it covered, and you might not have to push very hard. If trans is covered, then talk to your insurance provider.
If not, do you have problems with the organs in question? If you do, well, you might be able to get it covered. However, if you have been on T for a while, the provider might well try to argue that you did it to yourself unless you had a prior history of problems. (And they would probably still resist.) But I have heard of guys who managed to get hysto covered after a bit of a battle.
A few states now require insurance companies to cover trans stuff, but I don't know which states (apart from my own). You should be able to find some threads floating around.
I'm sure that some other folks will chime in with more information, but you really need to figure out what your policy covers.
