C33 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of trachea. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

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

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

MS-DRG	MS-DRG Title	MCD	Relative Weight
180	RESPIRATORY NEOPLASMS WITH MCC	04	1.6939
181	RESPIRATORY NEOPLASMS WITH CC	04	1.1337
182	RESPIRATORY NEOPLASMS WITHOUT CC/MCC	04	0.8875

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

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

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:

A lump or sore that does not heal
A sore throat that does not go away
Trouble swallowing
A change or hoarseness in the voice

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.
