(Urgent) Genioplasty Revision Method

Hello all. I got sliding Genioplasty with 6mm advancement 3 months ago. Recovery was tumultuous with infection, hematoma, nerve pain, and aesthetic issues. Upon further examination, the inferior mandible was shifted with partial left lateral anterior subluxation (the left side of my chin has shifted left and forward). My revision surgery is planned for next week, and my surgeon only billed my insurance for burring down the bone. What do you think about this? I’m concerned that they’re not repositioning it entirely, and that they’re just burring down one side.
