Yew has grown into a tree
This past winter caused a lot of damage. Should I wait to see if it comes back? A photo of the tree is included.
I am a bit unclear if your question is about the tree damage, the Yew plant that also is showing some winter damage, or both.

The Yew growing around the tree base could be an issue.
This can cause issues with root damage, damp conditions around the trunk not allowing air circulation can invite fungus and insects.
