Wiki Grafting for spine surgery

[afeaster72]

Hope someone can help with this one.
1. Revision left hemilaminotomy L5-S1
2. Left L5-S1 foraminotomy
3. L5-S1 diskectomy
4. [BApplication of epidural fat graft[/B]

Can I apply a graft code for this fat graft to the 63042?
Maybe 20926?

Thanks for your help!
