How do I turn in a Doctors visit (that doesn't accept insurance) to my insurance?

I am currently in Suboxone treatment and my clinic does not accept any insurances. Although, they told me that some insurance companies will reimburse the office visit. How do I go about turning this in on my insurance? Should I just contact my insurance company (Blue Cross & Blue Shield) directly?
