Compounded Prescriptions - Any way to get covered?

I was prescribed a compounded medication by my doctor and from what I was told by the compounding pharmacy and the doctor's staff, these are not normally covered by insurance. However, I was speaking with my local pharmacist (not at the compounding pharmacy) who told me there may be a way to submit the prescription to the insurance after the fact and have it partially covered if I list out the medications in it? Is this a thing? And if so, what questions would I need to ask my insurance to find out? I have Anthem BCBS through my employer if it matters. Thanks for any guidance you can give me on this. It's a $400 medication and money is really tight right now so any cost reduction would be helpful.
