Understanding the Mesothelioma ICD9 Code : mesothelioma.id

Hello and welcome to this comprehensive guide on the mesothelioma ICD9 code. In this journal article, we’ll be discussing everything you need to know about this medical code, including its definition, uses, coding guidelines, and more.

What is the Mesothelioma ICD9 Code?

The mesothelioma ICD9 code, also known as the International Classification of Diseases, Ninth Revision code, is a medical code used to identify and classify mesothelioma in patients. Mesothelioma is a rare form of cancer that affects the tissue that lines various organs in the body, most commonly the lungs. It is caused by exposure to asbestos, a naturally occurring mineral that was once widely used in construction and manufacturing.

Mesothelioma ICD9 Code Definition

The mesothelioma ICD9 code is a five-digit alphanumeric code that is used to classify mesothelioma in patients. The code identifies the location and type of mesothelioma, as well as any associated symptoms or complications.

Uses of the Mesothelioma ICD9 Code

The mesothelioma ICD9 code is used by healthcare providers, researchers, and insurers to track the prevalence and incidence of mesothelioma in populations. It also helps with billing and reimbursement for medical services related to mesothelioma treatment.

Coding Guidelines for Mesothelioma ICD9 Code

There are specific coding guidelines that must be followed when using the mesothelioma ICD9 code. These guidelines are designed to ensure accuracy and consistency in coding. Some of the key guidelines include:

– Use the most specific code available to describe the type and location of mesothelioma
– Use additional codes to describe any associated symptoms or complications
– Use separate codes for bilateral mesothelioma
– Use a secondary code to describe any underlying asbestos exposure

Table 1: Mesothelioma ICD9 Code Examples

Mesothelioma Type ICD9 Code Description
Pleural mesothelioma 163.0 Malignant neoplasm of pleura
Peritoneal mesothelioma 158.8 Malignant neoplasm of retroperitoneum and peritoneum, other and unspecified
Pericardial mesothelioma 164.8 Malignant neoplasm of other and ill-defined sites within the respiratory system and intrathoracic organs

FAQs about the Mesothelioma ICD9 Code

What is the difference between the ICD9 and ICD10 codes for mesothelioma?

The ICD10 code is a newer version of the ICD9 code that provides more specificity and detail in coding for mesothelioma. The ICD10 code includes separate codes for the histology, laterality, and extent of the disease, whereas the ICD9 code uses a more general classification system.

Does the mesothelioma ICD9 code apply to all types of mesothelioma?

Yes, the mesothelioma ICD9 code is used to classify all types of mesothelioma, including pleural, peritoneal, and pericardial mesothelioma.

Can the mesothelioma ICD9 code be used for billing and reimbursement purposes?

Yes, the mesothelioma ICD9 code can be used for billing and reimbursement purposes related to mesothelioma treatment. However, it is important to ensure that the code is used correctly and in accordance with coding guidelines.

Is the mesothelioma ICD9 code used internationally?

No, the mesothelioma ICD9 code is an outdated coding system that is no longer used by most countries. The newer ICD10 coding system is now used globally to classify and code diseases and conditions.

Symptom ICD9 Code Description
Pain in chest 786.50 Chest pain, unspecified
Dyspnea 786.05 Shortness of breath
Weight loss 783.21 Loss of weight


In conclusion, the mesothelioma ICD9 code is a vital classification system used to identify, classify, and track mesothelioma in patients. It helps healthcare providers, researchers, and insurers to accurately and consistently code and bill for mesothelioma treatment. It is important to follow coding guidelines and use the most specific code available to ensure accuracy in coding.
