Collaborative Stage

Collaborative Stage for TNM 7 - Revised 09/26/2010 [ Schema ]

LarynxOther

CS Extension

Note 1: Impaired vocal cord mobility may be described as vocal cord paresis, and may suggest invasion of intrinsic laryngeal muscle. Fixation of the vocal cord maybe described as immobility of the arytenoids noted on endoscopy, paralysis of the vocal cords, or deviation of larynx to the fixed side.
Note 2: Use code 450 for localized tumor only if no information is available to assign codes 100 through 400.
Note 3: Use code 375, 630, 775, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.
