Code Classification

  • Neoplasms
    (C00–D49)
    • Benign neoplasms, except benign neuroendocrine tumors
      (D10-D36)
      • Other benign neoplasms of connective and other soft tissue
        (D21)

D21.3 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of connective and other soft tissue of thorax. 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 aorta (thoracic) ; Neoplasm, neoplastic connective tissue NEC axilla ; Neoplasm, neoplastic connective tissue NEC chest (wall) ; Neoplasm, neoplastic connective tissue NEC diaphragm ; Neoplasm, neoplastic connective tissue NEC great vessels NEC ; Neoplasm, neoplastic connective tissue NEC infraclavicular region ; Neoplasm, neoplastic connective tissue NEC intrathoracic ; etc

Clinical Classification

Clinical Information

  • Contraceptive Devices, Female

    contraceptive devices used by females.

  • Diaphragm

    the musculofibrous partition that separates the thoracic cavity from the abdominal cavity. contraction of the diaphragm increases the volume of the thoracic cavity aiding inhalation.

  • Diaphragmatic Eventration

    a congenital abnormality characterized by the elevation of the diaphragm dome. it is the result of a thinned diaphragmatic muscle and injured phrenic nerve, allowing the intra-abdominal viscera to push the diaphragm upward against the lung.

  • Hernia, Diaphragmatic

    protrusion of abdominal structures into the thorax as a result of congenital or traumatic defects in the respiratory diaphragm.

  • Hernia, Diaphragmatic, Traumatic

    the type of diaphragmatic hernia caused by trauma or injury, usually to the abdomen.

  • Hernias, Diaphragmatic, Congenital

    protrusion of abdominal structures into the thorax as a result of embryologic defects in the diaphragm often present in the neonatal period. it can be isolated, syndromic, non-syndromic or be a part of chromosome abnormality. associated pulmonary hypoplasia and pulmonary hypertension can further complicate stabilization and surgical intervention.

  • Inferior Wall Myocardial Infarction

    myocardial infarction in which the inferior wall of the heart is involved. it is often caused by occlusion of the right coronary artery.

  • Pelvic Floor

    soft tissue formed mainly by the pelvic diaphragm, which is composed of the two levator ani and two coccygeus muscles. the pelvic diaphragm lies just below the pelvic aperture (outlet) and separates the pelvic cavity from the perineum. it extends between the pubic bone anteriorly and the coccyx posteriorly.

  • Peritoneal Stomata

    natural openings in the subdiaphragmatic lymphatic plexus in the peritoneum, delimited by adjacent mesothelial cells. peritoneal stomata constitute the principal pathways for the drainage of intraperitoneal contents from the peritoneal cavity to the lymphatic system.

  • Respiratory Paralysis

    complete or severe weakness of the muscles of respiration. this condition may be associated with motor neuron diseases; peripheral nerve diseases; neuromuscular junction diseases; spinal cord diseases; injury to the phrenic nerve; and other disorders.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Benign neoplasm of axilla
  • Benign neoplasm of diaphragm
  • Benign neoplasm of great vessels

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • benign neoplasm of heart D15.1
  • benign neoplasm of mediastinum D15.2
  • benign neoplasm of thymus D15.0

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.
