Code Classification

  • Neoplasms
    (C00–D49)
    • Benign neoplasms, except benign neuroendocrine tumors
      (D10-D36)
      • Benign neoplasm of other and unspecified intrathoracic organs
        (D15)

D15.2 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of mediastinum. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis 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 .

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • 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
  • Benign neoplasm of posterior mediastinum
  • Benign neoplasm of superior mediastinum
  • Ganglioneuroma
  • Ganglioneuroma of mediastinum
  • Neoplasm of anterior mediastinum
  • Neoplasm of posterior mediastinum
  • Neoplasm of posterior mediastinum

Clinical Classification

Clinical Information

  • Ganglioneuroma

    a benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. the tumor may present clinically with horner syndrome or diarrhea due to ectopic production of vasoactive intestinal peptide. (from devita et al., cancer: principles and practice of oncology, 5th ed, p966)
  • Horner Syndrome

    a syndrome associated with defective sympathetic innervation to one side of the face, including the eye. clinical features include miosis; mild blepharoptosis; and hemifacial anhidrosis (decreased sweating)(see hypohidrosis). lesions of the brain stem; cervical spinal cord; first thoracic nerve root; apex of the lung; carotid artery; cavernous sinus; and apex of the orbit may cause this condition. (from miller et al., clinical neuro-ophthalmology, 4th ed, pp500-11)

Table of Neoplasms

This code is referenced 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.

Patient Education


Benign 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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
