About the 0NT Code Range
These procedures remove an entire listed head or facial bone, or the bony orbit, without replacing it.

The fifth character specifies an Open approach, which exposes the site through the skin or mucous membrane. The sixth character is No Device, and the seventh is No Qualifier.
