]> C32.3 Laryngeal cartilage C32.8 Overlapping lesion of larynx C32.9 Larynx, NOS Note: AJCC 7 TNM staging will be derived for primary site codes of C32.8 and C32.9 only &generalsize; 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.

The complete definitions are provided in the General Rules, Section 2. Note 2: For head and neck schemas, additional information about lymph nodes (size of involved nodes, extracapsular extension, levels involved, and location of involved nodes above or below the lower border of the cricoids cartilage) is coded in CS Site-Specific Factors 1, 3-9. Note 3: If laterality of lymph nodes is not specified, assume nodes are ipsilateral. Midline nodes are considered ipsilateral. Note 4: For head and neck cancers, if lymph nodes are described only as "supraclavicular", try to determine if they are in Level IV (deep to the sternocleidomastoid muscle, in the lower jugular chain) or Level V (in the posterior triangle, inferior to the transverse cervical artery) and code appropriately. If the specific level cannot be determined, consider them as Level V nodes. Note 5: The description of lymph nodes has been standardized across the head and neck schemas. All lymph node levels and groups listed here are considered regional nodes for AJCC staging. Summary Stage 1977 and Summary Stage 2000 divide these nodes into regional and distant groups. Note 6: Level III and Level IV nodes have been moved from code 100 in CS Version 1 to code 110. Mandibular nodes are included with Facial nodes.
