CS Extension

Note 1: Involvement of or extension to bone ncludes any type of tumor extension to the bone, such as erosion, invasion, extension, penetration, or destruction.
Note 2: Use code 300 for localized tumor only if no information is available to assign code 100.
Note 3: Code Base of skull, NOS only if no information available to code to more specific bony structures in skull.
Note 4: Use code 665, 685, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.
