Was your endometrial cancer tested for mutations in the gene POLE?

I recently received the pathology results (Stage 1B Grade 3 endometriod carcinoma) on the specimens from my TH-BSO. I had thought that endometrial cancers like this would be routinely tested for mutations in a gene called POLE, which confers a better prognosis, but my sample was not. Apparently this is not part of the algorithm at the university hospital where I am being treated. They say they're working on offering this test, but that doesn't help me.

I have tried to ask my care team what my options are for getting this test done, but so far the only thing they mentioned is an extravagant sequencing test that isn't covered by insurance and seems to cost ~$6000. This is overkill, and way more than I would be willing to pay out of pocket.

Has anyone had POLE mutation testing done on their tumor specimen? If so, where where was this testing was performed? Did insurance cover it? How much did it cost?
