Collaborative Stage

Collaborative Stage for TNM 7 - Revised 09/30/2010 [ Schema ]

LarynxGlottic

CS Extension

Note 1: Impaired vocal cord mobility, also described as vocal cord paresis, may suggest invasion of intrinsic laryngeal muscle. Fixation of the vocal cord may be described as immobility of the arytenoids noted on endoscopy, vocal cord paralysis, or deviation of larynx to 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 130, 375, 530, 775, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.
