Valid for Submission
C38.4 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of pleura. The code C38.4 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 C38.4 might also be used to specify conditions or terms like malignant neoplasm of parietal pleura, malignant neoplasm of visceral pleura, malignant tumor of pleura, neoplasm of parietal pleura, neoplasm of visceral pleura , primary malignant neoplasm of parietal pleura, etc.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: pleura, pleural (cavity) or pleura, pleural (cavity) parietal or pleura, pleural (cavity) visceral .
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Malignant neoplasm of parietal pleura
- Malignant neoplasm of visceral pleura
- Malignant tumor of pleura
- Neoplasm of parietal pleura
- Neoplasm of visceral pleura
- Primary malignant neoplasm of parietal pleura
- Primary malignant neoplasm of pleura
- Primary malignant neoplasm of visceral pleura
- T1: Tumor limited to ipsilateral parietal and/or visceral pleura
- T2: Pleural tumor invades any of the following: ipsilateral lung, endothoracic fascia, diaphragm, or pericardium
- T3: Pleural tumor invades any of the following: ipsilateral chest wall muscle, ribs, or media-stinal organs or tissues
- T4: Pleural tumor directly extends to any of the following: contralateral pleura, contralateral lung, peritoneum, intra-abdominal organs, cervical tissues

|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|180||RESPIRATORY NEOPLASMS WITH MCC||04||1.7378|
|181||RESPIRATORY NEOPLASMS WITH CC||04||1.1209|
|182||RESPIRATORY NEOPLASMS WITHOUT CC/MCC||04||0.7875|
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.
Convert C38.4 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C38.4 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Table of Neoplasms
The code C38.4 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
Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, immunotherapy or other types of biologic therapy, or stem cell transplantation.

Your pleura is a large, thin sheet of tissue that wraps around the outside of your lungs and lines the inside of your chest cavity. Between the layers of the pleura is a very thin space. Normally it's filled with a small amount of fluid. The fluid helps the two layers of the pleura glide smoothly past each other as your lungs breathe air in and out.
Disorders of the pleura include
- Pleurisy - inflammation of the pleura that causes sharp pain with breathing
- Pleural effusion - excess fluid in the pleural space
- Pneumothorax - buildup of air or gas in the pleural space
- Hemothorax - buildup of blood in the pleural space
Many different conditions can cause pleural problems. Viral infection is the most common cause of pleurisy. The most common cause of pleural effusion is congestive heart failure. Lung diseases, like COPD, tuberculosis, and acute lung injury, cause pneumothorax. Injury to the chest is the most common cause of hemothorax. Treatment focuses on removing fluid, air, or blood from the pleural space, relieving symptoms, and treating the underlying condition.
