C32.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of glottis. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic commissure laryngeal ; Neoplasm, neoplastic cord (true) (vocal) ; Neoplasm, neoplastic glottis ; Neoplasm, neoplastic larynx, laryngeal NEC commissure (anterior) (posterior) ; Neoplasm, neoplastic larynx, laryngeal NEC intrinsic ; Neoplasm, neoplastic vocal cords (true) ; etc

Approximate Synonyms

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

  • Carcinoma of glottis
  • Carcinoma of vocal cord
  • Malignant tumor of anterior commissure
  • Malignant tumor of glottis
  • Malignant tumor of posterior commissure
  • Malignant tumor of vocal cord
  • Primary carcinoma of glottis
  • Primary carcinoma of larynx
  • Primary carcinoma of larynx
  • Primary carcinoma of vocal cord
  • Primary malignant neoplasm of glottis
  • Primary malignant neoplasm of laryngeal commissure

Clinical Classification

Clinical Information

  • Glottis

    the vocal apparatus of the larynx, situated in the middle section of the larynx. glottis consists of the vocal folds and an opening (rima glottidis) between the folds.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.

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 intrinsic larynx
  • Malignant neoplasm of laryngeal commissure (anterior)(posterior)
  • Malignant neoplasm of vocal cord (true) NOS

Convert C32.0 to ICD-9-CM

  • ICD-9-CM Code: 161.0 - Malignant neo glottis

Table of Neoplasms

This code is referenced 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.

Patient Education

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 drugs or other substances that attack specific cancer cells with less harm to normal cells.
