2022 ICD-10-CM Code C33

Malignant neoplasm of trachea

Version 2021

Valid for Submission

ICD-10:C33
Short Description:Malignant neoplasm of trachea
Long Description:Malignant neoplasm of trachea

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of respiratory and intrathoracic organs (C30-C39)
      • Malignant neoplasm of trachea (C33)

C33 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of trachea. The code C33 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code C33 might also be used to specify conditions or terms like acantholytic squamous cell carcinoma, adenoid cystic carcinoma of trachea, adenosquamous cell carcinoma, lymphoepithelial carcinoma, malignant neoplasm of carina of bronchus , malignant neoplasm of cartilage of trachea, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] trachea or trachea (cartilage) (mucosa) or windpipe .

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 coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C33:

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Approximate Synonyms

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

Table of Neoplasms

The code C33 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


Head and Neck Cancer

Head and neck cancer includes cancers of the mouth, nose, sinuses, salivary glands, throat, and lymph nodes in the neck. Most begin in the moist tissues that line the mouth, nose, and throat. Symptoms include

Head and neck cancers are twice as common in men. Using tobacco or alcohol increases your risk. In fact, around 75% of head and neck cancers are linked to tobacco use, including smoking and smokeless tobacco. Infection with HPV is a risk factor for some head and neck cancers.

To diagnose head and neck cancer, your doctor will do a physical exam and diagnostic tests. You will have a biopsy, where a sample of tissue is taken out and examined under a microscope. It is the only test that can tell for sure if you have cancer.

If found early, these cancers are often curable. Treatments may include surgery, radiation therapy, chemotherapy, or a combination. Treatments can affect eating, speaking or even breathing, so patients may need rehabilitation.

Tracheal Disorders

Your trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. They also carry carbon dioxide, a waste gas, out of your lungs.

When you inhale, air travels from your nose, through your larynx, and down your windpipe. The windpipe splits into two bronchi that enter your lungs.

Problems with the trachea include narrowing, inflammation, and some inherited conditions. You may need a procedure called a tracheostomy to help you breathe if you have swallowing problems, or have conditions that affect coughing or block your airways. You might also need a tracheostomy if you are in critical care and need to be on a breathing machine.
