ICD-10-CM Code D15.2

Benign neoplasm of mediastinum

Version 2021 Billable Code Neoplasm Benign

Valid for Submission

D15.2 is a billable code used to specify a medical diagnosis of benign neoplasm of mediastinum. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code D15.2 might also be used to specify conditions or terms like anterior mediastinum mass, benign mediastinal teratoma, benign neoplasm of lower anterior mediastinum, benign neoplasm of lower middle mediastinum, benign neoplasm of lower posterior mediastinum, benign neoplasm of mediastinum, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic mediastinum, mediastinal or Neoplasm, neoplastic mediastinum, mediastinal anterior or Neoplasm, neoplastic mediastinum, mediastinal posterior or Neoplasm, neoplastic substernal .

Diagnostic Related Groups

The ICD-10 code D15.2 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2020 through 09/30/2021.

Table of Neoplasms

The code D15.2 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


Benign Tumors

Also called: Benign neoplasms, Noncancerous tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.
