Facility Fee Office 99199

I am a physician office with a dedicated surgical suite. I have a C-Arm and CRNA. I am constantly given push back from WC and commercial payers for billing 99199(Facility Fee). BCBS stated that there is a better facility fee code to be used, does anyone know what this code is? I am not an ambulatory surgery center we are a doctor's office.

Please help I have a new coder!
