Understanding Peritoneal Mesothelioma ICD9: A Comprehensive Guide : mesothelioma.id

Hello and welcome to our definitive guide on peritoneal mesothelioma ICD9. In this article, we will cover everything you need to know about this rare form of cancer, including its symptoms, diagnosis, treatment options, and more. Mesothelioma is a type of cancer that affects the mesothelial cells that line the body’s internal organs. Peritoneal mesothelioma is a form of this cancer that affects the lining of the abdominal cavity. If you or someone you know has been diagnosed with peritoneal mesothelioma, this guide is for you. Let’s get started.

What is Peritoneal Mesothelioma?

Peritoneal mesothelioma is a rare form of cancer that affects the lining of the abdominal cavity. The disease is caused by exposure to asbestos, a mineral once commonly used in building materials such as insulation, roofing, and flooring. When asbestos fibers are inhaled or ingested, they can become lodged in the lining of the organs, causing damage and leading to cancer.

The symptoms of peritoneal mesothelioma can be vague and nonspecific, making diagnosis difficult. However, early detection is crucial for effective treatment. Let’s take a closer look at the symptoms of this disease.

Symptoms of Peritoneal Mesothelioma

The symptoms of peritoneal mesothelioma can include:

  • Abdominal pain and swelling
  • Nausea and vomiting
  • Loss of appetite
  • Weight loss
  • Fluid buildup in the abdomen (ascites)

These symptoms can be similar to those of other abdominal conditions, making diagnosis challenging. If you are experiencing any of these symptoms and have a history of asbestos exposure, it’s essential to see a doctor right away.

Diagnosis of Peritoneal Mesothelioma

Diagnosing peritoneal mesothelioma can be challenging, and several tests may be necessary to determine if you have this type of cancer. Let’s take a closer look at the diagnostic process.

Imaging Tests

Your doctor may order imaging tests, such as X-rays, CT scans, or MRI scans, to look for abnormalities in your abdominal cavity. These tests can help identify any tumors or fluid buildup in the abdomen.


A biopsy is the most definitive way to diagnose peritoneal mesothelioma. During a biopsy, a small sample of tissue is removed from the lining of the abdomen and examined under a microscope for cancer cells. There are several ways to perform a biopsy, including:

  • Fine-needle aspiration biopsy
  • Core biopsy
  • Surgical biopsy

Your doctor will determine which type of biopsy is best for you based on your specific circumstances.

Peritoneal Mesothelioma ICD9 Code

The ICD9 code for peritoneal mesothelioma is 158.8. This code is used to identify the disease in medical records and for insurance billing purposes. It’s essential to ensure that your medical records accurately reflect your diagnosis to ensure that you receive the appropriate treatment and care.

Treatment Options for Peritoneal Mesothelioma

Peritoneal mesothelioma is a challenging disease to treat, and there is no cure. However, several treatment options can help manage the symptoms and improve quality of life. Let’s take a closer look at these options.


Surgery may be an option for some patients with peritoneal mesothelioma. The goal of surgery is to remove as much of the tumor as possible and slow the progression of the disease. Several surgical procedures can be used, including:

  • Debulking surgery
  • Cytoreductive surgery
  • Peritonectomy

These procedures can be complex and carry a significant risk of complications, so they are typically reserved for patients who are otherwise healthy and have a good chance of benefiting from surgery.


Chemotherapy involves using drugs to kill cancer cells. It can be administered orally or intravenously and is often used in combination with surgery or radiation therapy. Common chemotherapy drugs used to treat peritoneal mesothelioma include:

  • Cisplatin
  • Carboplatin
  • Alimta

Chemotherapy can cause side effects, such as nausea, fatigue, and hair loss.

Radiation Therapy

Radiation therapy uses high-energy beams to kill cancer cells. It’s often used in combination with surgery or chemotherapy to control the growth and spread of cancer. Radiation therapy can cause side effects, such as fatigue, skin irritation, and nausea.

Living with Peritoneal Mesothelioma: FAQs

If you or a loved one has been diagnosed with peritoneal mesothelioma, you likely have many questions about the disease and its treatment. Here are some frequently asked questions about living with peritoneal mesothelioma.

Q: Is peritoneal mesothelioma curable?

A: There is no cure for peritoneal mesothelioma, but treatments are available that can help manage the symptoms and improve quality of life.

Q: What is the prognosis for peritoneal mesothelioma?

A: The prognosis for peritoneal mesothelioma varies depending on several factors, including the stage of the disease, the patient’s overall health, and the treatment options available. However, the disease is often challenging to treat, and the 5-year survival rate is approximately 20%.

Q: Can peritoneal mesothelioma be prevented?

A: The primary cause of peritoneal mesothelioma is exposure to asbestos, so avoiding exposure to this mineral is the best way to reduce your risk of developing the disease. If you work with asbestos or in a building that contains asbestos, take all necessary precautions to limit your exposure, such as wearing protective clothing and equipment and following proper safety protocols.

Q: What should I do if I think I have peritoneal mesothelioma?

A: If you are experiencing symptoms of peritoneal mesothelioma, such as abdominal pain or swelling, nausea, or weight loss, see a doctor right away. Be sure to inform your doctor of any history of asbestos exposure, as this can help with diagnosis and treatment.


Peritoneal mesothelioma is a rare and challenging disease, but with proper diagnosis and treatment, it’s possible to manage the symptoms and improve quality of life. If you have been diagnosed with peritoneal mesothelioma, work closely with your doctor to develop a treatment plan that is tailored to your specific needs and circumstances. With the right care and support, it’s possible to live a full and satisfying life with this disease.
