Wiki Need help with ASC billing for Angio w/Atherectomy

We have recevied denial from BcBs for billing 75710-TC, 59 and 37225-LT in a ASC setting. The provider did a LE angio with PTA w/Atherectomy on the left leg. Is this not the correct codes to bill?? I'm I missing something?!? ASC billing is new to me and if I am not billing this correctly please please fill me in!!! Any help would be greatly appreciated!!!!!!!

If youre billing for the ASC, and not the provider then the angiograms are packaged and not billable- only the 37225
this is a helpful guide of whats packaged and what isnt

CPT 37225 code usually is denied under 197 denial code. If so, the provider should have Prior Authorization in place before performing the invasive procedure.
What are the CARC and RARC?
