Notes
**Note 1**: If there is fixation of hemilarynx or larynx, code to 550, not 420 or 450. **Note 2**: Use code 300 for localized tumor only if no information is available to assign code 100, 200, or 305. **Note 3**: Use code 305, 455, 565, 638, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.Default
