I believe it's not possible to represent the chirality of the attached molecule's ring fusion carbons without using an explicit H.

Is it always possible to represent an organic molecule in 2D with all necessary configuration hints (bond wedges pointing to the front or to the back) without introducing any explicit hydrogen atom? May be my question is very naive, all my apologies in advance for that.
