Notes
**Note 1:** Periosteum is a fibrous membrane that wraps the outer surface of bones. Mucoperiosteum is a compound structure of mucous membrane and periosteum. Cortical bone is the dense compact outer layer of bone. **Note 2:** Macroscopic extraparenchymal extension (code 300) is based on clinical evaluation or macroscopic evidence of extraparenchymal extension at the time of surgery.Default
