Mesothelioma ICD Code: Understanding the Classification and Diagnosis of the Disease :

Hello and welcome to this comprehensive guide on mesothelioma ICD code. If you or a loved one has been diagnosed with mesothelioma, you may have come across the term “ICD code” while discussing treatment options with your healthcare provider. In this article, we will provide a detailed overview of mesothelioma ICD code, including its classification, diagnosis, and treatment options.

What is Mesothelioma?

Mesothelioma is a rare and aggressive form of cancer that develops in the mesothelial cells, which are the protective lining that covers the internal organs of the body. This disease is primarily caused by exposure to asbestos, a naturally occurring mineral that was commonly used in construction materials and other products prior to its ban in the 1970s.

The symptoms of mesothelioma can take decades to develop, and they often mimic those of other respiratory conditions, making early diagnosis challenging. However, with advancements in medical technology and increased awareness of the disease, mesothelioma can be detected and treated at an earlier stage.

What is ICD Code?

ICD code stands for International Classification of Diseases code. This is a system of alphanumeric codes that are used to classify medical conditions and diseases for the purpose of diagnosis, treatment, and reimbursement. ICD codes are updated periodically to ensure that they reflect the most current medical knowledge and terminology.

In the case of mesothelioma, the ICD code is used by doctors and other healthcare providers to classify the disease for diagnostic and treatment purposes. A correct ICD code is also essential for insurance billing purposes.

ICD-10 Code for Mesothelioma

The current version of ICD code is ICD-10, which was introduced by the World Health Organization (WHO) in 1990. The ICD-10 code for mesothelioma is C45, which falls under the category of “Malignant neoplasms of mesothelial and soft tissue.”

In addition to the primary code of C45, there are also secondary codes that can be used to describe the location and laterality of the mesothelioma. These codes are as follows:

Site/Location ICD-10 Code
Peritoneum C45.0
Pleura C45.1
Pericardium C45.2
Other sites C45.7
Unspecified site C45.9

Diagnosing Mesothelioma with ICD Code

The diagnosis of mesothelioma typically involves a combination of imaging tests, such as X-rays, CT scans, and MRIs, as well as a biopsy of the affected tissue. Once mesothelioma has been confirmed, the doctor will assign the appropriate ICD code to the patient’s medical record.

It is important to note that mesothelioma can be difficult to diagnose, as the symptoms can mimic those of other respiratory conditions. As a result, it is essential for patients with a history of asbestos exposure to inform their healthcare provider, as this will help with early detection and diagnosis of the disease.

Mesothelioma FAQs

Q: What are the risk factors for mesothelioma?

A: The primary risk factor for mesothelioma is exposure to asbestos. Other risk factors include a family history of mesothelioma, radiation exposure, and certain genetic mutations.

Q: What are the symptoms of mesothelioma?

A: The symptoms of mesothelioma can vary depending on the location of the cancer, but they often include shortness of breath, chest pain, coughing, weight loss, and fatigue.

Q: How is mesothelioma treated?

A: The treatment options for mesothelioma depend on the stage of the disease and the patient’s overall health. Treatment may include surgery, chemotherapy, radiation therapy, or a combination of these therapies. In some cases, clinical trials may be an option.

Q: What is the survival rate for mesothelioma?

A: The survival rate for mesothelioma depends on several factors, such as the stage of the disease, the location of the cancer, and the patient’s overall health. According to the American Cancer Society, the five-year survival rate for mesothelioma is approximately 20%.

Q: How can I reduce my risk of developing mesothelioma?

A: The best way to reduce your risk of developing mesothelioma is to avoid exposure to asbestos. If you work in an industry that involves asbestos, be sure to follow all safety protocols and wear protective gear. It is also important to seek medical attention if you suspect that you may have been exposed to asbestos.


Mesothelioma is a rare and aggressive form of cancer that can be challenging to diagnose and treat. However, with the right knowledge and tools, patients and healthcare providers can work together to manage the disease and improve the patient’s quality of life. By understanding the mesothelioma ICD code and its role in diagnosis and treatment, patients and their loved ones can be better equipped to navigate the complexities of this disease.
