The ICD-10-CM code C32.1 might also be used to specify conditions or terms like carcinoma of larynx, carcinoma of supraglottis, malignant tumor of aryepiglottic fold - laryngeal aspect, malignant tumor of false cord, malignant tumor of infrahyoid epiglottis, malignant tumor of laryngeal ventricle, etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C32.1:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Malignant neoplasm of aryepiglottic fold or interarytenoid fold, laryngeal aspect
  • Malignant neoplasm of epiglottis (suprahyoid portion) NOS
  • Malignant neoplasm of extrinsic larynx
  • Malignant neoplasm of false vocal cord
  • Malignant neoplasm of posterior (laryngeal) surface of epiglottis
  • Malignant neoplasm of ventricular bands

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • malignant neoplasm of anterior surface of epiglottis C10.1
  • malignant neoplasm of aryepiglottic fold or interarytenoid fold, hypopharyngeal aspect C13.1
  • malignant neoplasm of aryepiglottic fold or interarytenoid fold, marginal zone C13.1
  • malignant neoplasm of aryepiglottic fold or interarytenoid fold NOS C13.1

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • pT3: Tumor limited to the larynx with vocal cord fixation and/or invades any of the following: postcrocoid area, pre-epiglottic tissues, paraglottic space, and/or minor thyroid cartilage erosion
  • pT4a: Tumor invades through the thyroid cartilage and/or invades tissues beyond the larynx
  • pT4b: Tumor invades prevertebral space, encases carotid artery, or invades mediastinal structures
  • Squamous cell carcinoma of epiglottis
  • Supraglottis TNM finding
  • Supraglottis TNM finding
  • Supraglottis TNM finding
  • Supraglottis TNM finding
  • Supraglottis TNM finding
  • T1: Tumor limited to one subsite of supraglottis with normal vocal cord mobility
  • Tumor of infrahyoid epiglottis
  • Tumor of laryngeal ventricle
  • Tumor of suprahyoid epiglottis

  • FY 2017 - No Change, effective from 10/1/2016 through 9/30/2017
  • FY 2018 - No Change, effective from 10/1/2017 through 9/30/2018
  • FY 2019 - No Change, effective from 10/1/2018 through 9/30/2019
  • FY 2020 - No Change, effective from 10/1/2019 through 9/30/2020

Table of Neoplasms

The code C32.1 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

The Tabular must be reviewed for the complete diagnosis code.

Information for Patients


Throat Cancer

Throat cancer is a type of head and neck cancer. Throat cancer has different names, depending on which part of the throat is affected. The different parts of your throat are called the oropharynx, the hypopharynx, the nasopharynx, and the larynx, or voice box.

The main risk factors for throat cancer are using tobacco heavy drinking. Certain types of throat cancer also have other risk factors. For example, having HPV is a risk factor for oropharyngeal cancer.

Symptoms of throat cancer may include

  • A sore throat that does not go away
  • A lump in the neck
  • Pain or ringing in the ears
  • Trouble swallowing
  • Ear pain

To diagnose throat cancers, doctors may do a physical exam and history, imaging tests, and a biopsy. You may also need other tests, depending on the type of cancer. Treatments include surgery, radiation therapy, and chemotherapy. Treatment for some types of throat cancer may also include targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.
