Just need a little assistance, one of the surgeon's in my office is going to be preforming a 'Image Guided Left Middle Fossa Craniotomy with repair of a Temporal Encephalocele and possible Fat or Fascia graft', the surgery scheduler has asked for help with the codes so we can be as accurate when getting an authorization through insurance. I have not coded this type of surgery before and I was wondering if I have the correct codes or if I missed anything by chance.

62120 (repair of encephalocele, skull vault, including cranioplasty)
+61781 (stereotactic computer assisted, cranial/intradural)
+20926 (tissue graft)

Thank you for any help :)
