SinusMaxillary

CS Extension

Note 1: Use code 300 for localized tumor ONLY if no information is available to assign code 100.
Note 2: Code Base of skull NOS only if no information available to code to more specific bony structures in skull.
Note 3: 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.
