Notes
**Note 1:** The orbital tissues are the support systems of the globe, confined to the space within the surrounding bony structure. The tissues include fat, striated and smooth muscle, fibroconnective, vascular, lymphoid, peripheral nerve, and optic nerve tissue. **Note 2:** In situ (code 000) may be used only for non-sarcoma histologies coded to this site. Sarcomas do not present as in situ or noninvasive tumors.Default
