Ask Dr. Z

During a port a cath placement, the provider stated the guidewire was inserted through needle and confirmed to travel to the IVC via x-ray imaging intraop. Later in the note he says x-ray was utilized to confirm location of the catheter at the atriocaval junction. I was advised by the audit team to query because fluoroscopy was not mentioned and we felt the 77001 was not supported. The provider responded that "x-ray is fluoroscopic guidance". Would this be enough documentation to support 77001? There is nothing else in the note, procedure list, or findings that mentions the fluoro guidance. Would you recommend an addendum as well?
