Not Valid for Submission
C34.3 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of malignant neoplasm of lower lobe, bronchus or lung. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: bronchus lower lobe of lung or lung lower lobe .
Specific Coding for Malignant neoplasm of lower lobe, bronchus or lung
Non-specific codes like C34.3 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for malignant neoplasm of lower lobe, bronchus or lung:
Table of Neoplasms
The code C34.3 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
What is lung cancer?
Lung cancer is cancer that forms in tissues of the lung, usually in the cells that line the air passages. It is the leading cause of cancer death in both men and women.
There are two main types: small cell lung cancer and non-small cell lung cancer. These two types grow differently and are treated differently. Non-small cell lung cancer is the more common type.
Who is at risk for lung cancer?
Lung cancer can affect anyone, but there are certain factors that raise your risk of getting it:
- Smoking. This is the most important risk factor for lung cancer. Tobacco smoking causes about 9 out of 10 cases of lung cancer in men and about 8 out of 10 cases of lung cancer in women. The earlier in life you start smoking, the longer you smoke, and the more cigarettes you smoke per day, the greater your risk of lung cancer. The risk is also greater if you smoke a lot and drink alcohol every day or take beta carotene supplements. If you have quit smoking, your risk will be lower than if you had kept smoking. But you will still have a higher risk than people who never smoked.
- Secondhand smoke, which is the combination of smoke that comes from a cigarette and smoke breathed out by a smoker. When you inhale it, you are exposed to the same cancer-causing agents as smokers, although in smaller amounts.
- Family history of lung cancer
- Being exposed to asbestos, arsenic, chromium, beryllium, nickel, soot, or tar in the workplace
- Being exposed to radiation, such as from
- Radiation therapy to the breast or chest
- Radon in the home or workplace
- Certain imaging tests such as CT scans
- HIV infection
- Air pollution
What are the symptoms of lung cancer?
Sometimes lung cancer does not cause any signs or symptoms. It may be found during a chest x-ray done for another condition.
If you do have symptoms, they may include
- Chest pain or discomfort
- A cough that doesn't go away or gets worse over time
- Trouble breathing
- Blood in sputum (mucus coughed up from the lungs)
- Loss of appetite
- Weight loss for no known reason
- Trouble swallowing
- Swelling in the face and/or veins in the neck
How is lung cancer diagnosed?
Your health care provider may use many tools to make a diagnosis:
- A medical history, which includes asking about your symptoms
- A family history
- A physical exam
- Imaging tests, such as a chest x-ray or chest CT scan
- Lab tests, including tests of your blood and sputum
- A biopsy of the lung
If you do have lung cancer, your provider will do other tests to find out how far it has spread through the lungs, lymph nodes, and the rest of the body. This is called staging. Knowing the type and stage of lung cancer you have helps your provider decide what kind of treatment you need.
What are the treatments for lung cancer?
For most patients with lung cancer, current treatments do not cure the cancer.
Your treatment will depend on which type of lung cancer you have, how far it has spread, your overall health, and other factors. You may get more than one type of treatment.
The treatments for small cell lung cancer include
- Radiation therapy
- Laser therapy, which uses a laser beam to kill cancer cells
- Endoscopic stent placement. An endoscope is a thin, tube-like instrument used to look at tissues inside the body. It may be used to put in a device called a stent. The stent helps to open an airway that has been blocked by abnormal tissue.
The treatments for non-small cell lung cancer include
- Radiation therapy
- Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells
- Laser therapy
- Photodynamic therapy (PDT), which uses a medicine and a certain type of laser light to kill cancer cells
- Cryosurgery, which uses an instrument to freeze and destroy abnormal tissue
- Electrocautery, a treatment that uses a probe or needle heated by an electric current to destroy abnormal tissue
Can lung cancer be prevented?
Avoiding the risk factors may help to prevent lung cancer:
- Quitting smoking. If you don't smoke, don't start.
- Lower your exposure to hazardous substances at work
- Lower your exposure to radon. Radon tests can show whether your home has high levels of radon. You can buy a test kit yourself or hire a professional to do the test.

Lung cancer is a disease in which certain cells in the lungs become abnormal and multiply uncontrollably to form a tumor. Lung cancer may not cause signs or symptoms in its early stages. Some people with lung cancer have chest pain, frequent coughing, blood in the mucus, breathing problems, trouble swallowing or speaking, loss of appetite and weight loss, fatigue, or swelling in the face or neck. Additional symptoms can develop if the cancer spreads (metastasizes) into other tissues. Lung cancer occurs most often in adults in their sixties or seventies. Most people who develop lung cancer have a history of long-term tobacco smoking; however, the condition can occur in people who have never smoked.
Lung cancer is generally divided into two types, small cell lung cancer and non-small cell lung cancer, based on the size of the affected cells when viewed under a microscope. Non-small cell lung cancer accounts for 85 percent of lung cancer, while small cell lung cancer accounts for the remaining 15 percent.
Small cell lung cancer grows quickly and in more than half of cases the cancer has spread beyond the lung by the time the condition is diagnosed. Small cell lung cancer often metastasizes, most commonly to the liver, brain, bones, and adrenal glands (small hormone-producing glands located on top of each kidney). After diagnosis, most people with small cell lung cancer survive for about 1 year; less than seven percent survive 5 years.
Non-small cell lung cancer is divided into three main subtypes: adenocarcinoma, squamous cell carcinoma, and large cell lung carcinoma. Adenocarcinoma arises from the cells that line the small air sacs (alveoli) located throughout the lungs. Squamous cell carcinoma arises from squamous cells that line the passages leading from the windpipe (trachea) to the lungs (bronchi). Large cell carcinoma arises from epithelial cells that line the lungs. Large cell carcinoma encompasses non-small cell lung cancers that do not appear to be adenocarcinomas or squamous cell carcinomas. The 5-year survival rate for people with non-small cell lung cancer is usually between 11 and 17 percent; it can be lower or higher depending on the subtype and stage of the cancer.
