Costco Hearing Center Reimbursement (Blue Shield Promise Health Plan Medi-cal (Medicaid))

Has anyone manage to get Hearing Aids reimbursement from Bue Shield Promise Health Plan Medi-cal for out of pocket hearing aids from Costco?

From my understanding, we have to submit the information such as authorization, itemized billing, health insurance coding, and test result to our insurance.

Since Costco is not a medi-cal provider would this any affect?
