Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Injuries to the thorax
      (S20-S29)
      • Injury of other and unspecified intrathoracic organs
        (S27)

S27.309A is a billable diagnosis code used to specify a medical diagnosis of unspecified injury of lung, unspecified, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

S27.309A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like unspecified injury of lung unspecified. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Unspecified diagnosis codes like S27.309A are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Acute Lung Injury

    a condition of lung damage that is characterized by bilateral pulmonary infiltrates (pulmonary edema) rich in neutrophils, and in the absence of clinical heart failure. this can represent a spectrum of pulmonary lesions, endothelial and epithelial, due to numerous factors (physical, chemical, or biological).
  • Transfusion-Related Acute Lung Injury

    a rare but serious transfusion-related reaction in which fluid builds up in the lungs unrelated to excessively high infusion rate and/or volume (transfusion-associated circulatory overload). signs of transfusion-related acute lung injury include pulmonary secretions; hypotension; fever; dyspnea; tachypnea; tachycardia; and cyanosis.
  • Chylothorax

    the presence of chyle in the thoracic cavity. (dorland, 27th ed)
  • Traumatic Chylothorax

    accumulation of lymph fluid in the pleural cavity as a result of thoracic trauma.
  • Acquired Chylothorax

    chylothorax that results from malignancies (usually lymphoma), trauma to the thoracic duct, tuberculosis, or sarcoidosis.
  • Chylothorax

    an accumulation of chyle in the pleural cavity.
  • Chylothorax, CTCAE|Chylothorax|Chylothorax|Chylothorax

    a disorder characterized by milky pleural effusion (abnormal collection of fluid) resulting from accumulation of lymph fluid in the pleural cavity.
  • Chylothorax|Chylous Pleural Effusion

    a milky pleural effusion resulting from accumulation of lymph fluid in the pleural cavity. causes include malignancies (usually lymphoma), trauma to the thoracic duct, tuberculosis, sarcoidosis, and congenital causes.
  • Congenital Chylothorax

    chylothorax that is present at birth.
  • Grade 1 Chylothorax, CTCAE|Grade 1 Chylothorax|Grade 1 Chylothorax

    asymptomatic; clinical or diagnostic observations only; intervention not indicated
  • Grade 2 Chylothorax, CTCAE|Grade 2 Chylothorax|Grade 2 Chylothorax

    symptomatic; medical intervention indicated (e.g., fat-restricted diet); thoracentesis or tube drainage indicated
  • Grade 3 Chylothorax, CTCAE|Grade 3 Chylothorax|Grade 3 Chylothorax

    severe symptoms; elective operative intervention indicated
  • Grade 4 Chylothorax, CTCAE|Grade 4 Chylothorax|Grade 4 Chylothorax

    life-threatening respiratory or hemodynamic compromise; intubation or urgent intervention indicated
  • Grade 5 Chylothorax, CTCAE|Grade 5 Chylothorax|Grade 5 Chylothorax

    death

Coding Guidelines

The appropriate 7th character is to be added to each code from block Injury of other and unspecified intrathoracic organs (S27). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Unspecified codes - Unspecified codes exist in the ICD-10-CM classification for circumstances when documentation in the medical record does not provide the level of detail needed to support reporting a more specific code. However, in the inpatient setting, there should generally be very limited and rare circumstances for which the laterality (right, left, bilateral) of a condition is unable to be documented and reported. The following pages contain the list of unspecified ICD-10-CM diagnosis codes for which there is a more specific code to identify laterality (right, left, bilateral) within that code family.

Convert S27.309A to ICD-9-CM

  • ICD-9-CM Code: 861.20 - Lung injury NOS-closed
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Chest Injuries and Disorders

What is the chest?

The chest is the part of your body between your neck and your abdomen (belly). The medical term for your chest is thorax.

Your chest holds many important structures for breathing, digestion, blood circulation, and other important body functions. These structures include your:

  • Ribs and breastbone
  • Esophagus, the tube between your mouth and stomach
  • Trachea, your windpipe
  • Bronchi, the tubes that carry air from your windpipe to your lungs
  • Lungs
  • Pleura, a thin layer of tissue that covers the lungs and lines the inside wall of the chest space
  • Heart and large blood vessels
  • Thymus, a gland that's part of your immune system
  • Nerves

What are chest injuries and disorders?

Chest injuries and disorders are problems that affect any of the organs or structures located in your chest.

There are many types of chest injuries and disorders, for example:

  • Broken ribs
  • Esophagus disorders
  • Swallowing disorders, also called dysphagia
  • Tracheal disorders
  • Bronchial disorders
  • Lung diseases and collapsed lung
  • Pleural disorders
  • Heart diseases
  • Mediastinal diseases, which are tumors, inflammation, and other problems with the structures in the mediastinum, which is the space between your lungs, breastbone, and spine
  • Thoracic aortic aneurysm
  • Thoracic outlet syndrome

Chest injuries may happen from the force of car accidents, falls, or sports injuries. Or the chest may be pierced by a bullet or sharp object. Because your chest holds so many important structures, certain chest injuries may be life-threatening.

How are chest injuries and disorders diagnosed?

Diagnosis of chest injuries or disorders depends on the type of symptoms you're having and whether you've had a chest injury. Injuries are usually obvious, but in most cases, you'll need tests to know how serious an injury is.

There are many types of tests for diagnosing different types of chest injuries and disorders, for example:

  • Diagnostic imaging tests
  • Heart tests
  • Lung function tests
  • Bronchoscopy
  • Pleural fluid analysis
  • Dysphagia tests
  • Biopsy

Treatments will depend on the type of chest injury or disorder you have.

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.
