Guidelines for Head and Neck The head and neck rules cover the following sites: Lip C000-C009, Oral Cavity C019-C069, Salivary Gland C079-C089, Tonsil C090-C099, Oropharynx C100-C109, Nasopharynx C110-C119, Pyriform Sinus C129, Hypopharynx C130-C139, Other and Ill-defined Sites in Lip, Oral cavity and Pharynx C140-C148, Nasal Cavity C300, Middle Ear C301, Accessory Sinuses C310-C319, and Larynx C320-C329.
Head and neck tumors frequently extend into adjacent anatomic sites, or overlap multiple contiguous sites. The workup for these tumors often includes physical examinations, imaging, scans, endoscopies, biopsies and surgical observations. Each of these diagnostic tools provides a unique view of the tumor. More than one anatomic location may be involved with tumor and reports may contain conflicting information regarding the primary site.
Coding the Primary Site Code the site where the tumor originated; do not simply code the biopsy site.
When there are multiple biopsies and the primary site is not documented, or when there is discrepant information, code the primary site using the following priority order.
Priority Order 1. Tumor board a. Specialty b. General 2. Staging physician’s site assignment a. AJCC staging form b. TNM statement in medical record
If neither 1 nor 2 are available, the priority order for using information depends upon whether the patient had a surgical resection of the primary tumor.
3. Total (complete) resection of primary tumor
Note: The primary tumor is completely removed. The surgical margins may be microscopically positive.
a. Surgeon’s statement from operative report b. Final diagnosis from pathology report

4. No resection (biopsy only): Documentation from:
a. Endoscopy (physical exam with scope) b. Radiation oncologist c. Diagnosing physician d. Primary care physician e. Other physician f. Radiologist impression from diagnostic imaging g. Physician statement based on physical exam (clinical impression)
When the point of origin cannot be determined, use a topography code for overlapping sites: • C02.8 Overlapping lesion of tongue • C08.8 Overlapping lesion of major salivary glands • C14.8 Overlapping lesion of lip, oral cavity, and pharynx.
Equivalent or Equal Terms • In situ, noninvasive, intraepithelial • Squamous cell carcinoma, squamous cell epithelioma, epidermoid carcinoma • Tumor, mass, lesion, neoplasm • Contiguous, continuous
Definitions
In Situ: A tumor that is confined to the epithelium without penetration of the basement membrane
Invasive: A tumor that penetrates the basement membrane and involves at least the lamina propria
Most invasive: The tumor with the greatest continuous extension (see focal and foci definitions in the general instructions). The least to the greatest extension for mouth and oral cavity:
• epithelium • lamina propria, submucosa (not found in gum and hard palate) • muscularis propria (not found in gum and hard palate)

Chart 1 – Head and Neck Histology Groups and Specific types
Note: Greater than 85% of cancers in the Head and Neck are squamous cell carcinoma
Chart Instructions: Use this chart with the histology rules to code the most specific histologic term. The tree is arranged in descending order. Each branch is a histology group, starting with the NOS or group terms and descending into the specific types for that group. As you follow the branch down, the terms become more specific.

Undifferentiated Carcinoma (8020)

Papillary carcinoma (8050) Verrucous carcinoma (8051) Papillary squamous cell carcinoma; Papillary epidermoid carcinoma
