ICD-10-CM Code C32.3

Malignant neoplasm of laryngeal cartilage

Version 2020 Billable Code Neoplasm Malignant Primary

Valid for Submission

C32.3 is a billable code used to specify a medical diagnosis of malignant neoplasm of laryngeal cartilage. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C32.3 might also be used to specify conditions or terms like malignant neoplasm of arytenoid cartilage, malignant neoplasm of cricoid cartilage, malignant neoplasm of cuneiform cartilage, malignant neoplasm of thyroid cartilage, malignant tumor of laryngeal cartilage, primary malignant neoplasm of laryngeal cartilage, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: arytenoid (cartilage) ; cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] arytenoid ; cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] cricoid ; cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] cuneiform ; cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] larynx, laryngeal ; cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] thyroid ; cricoid cartilage ; etc

Short Description:Malignant neoplasm of laryngeal cartilage
Long Description:Malignant neoplasm of laryngeal cartilage


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

  • Malignant neoplasm of arytenoid cartilage
  • Malignant neoplasm of cricoid cartilage
  • Malignant neoplasm of cuneiform cartilage
  • Malignant neoplasm of thyroid cartilage
  • Malignant tumor of laryngeal cartilage
  • Primary malignant neoplasm of laryngeal cartilage
  • Primary squamous cell carcinoma of laryngeal cartilage
  • Tumor of arytenoid

Table of Neoplasms

The code C32.3 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.

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.
