What S27 covers · when clinicians use it
ICD-10 code S27 identifies Injury of other and unspecified intrathoracic organs in the U.S. ICD-10-CM clinical and billing record set. It sits within the Injury, Poisoning & External Causes chapter (S00–T88), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply S27 when an encounter's findings match the Injury of other and unspecified intrathoracic organs description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify S27 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for S27 and is a coding reference, not clinical, diagnostic, or billing advice.
ICD10 code S27 is used to document Injury of other and unspecified intrathoracic organs, covering injuries affecting the chest wall, ribcage, spine, heart, blood vessels, and other thoracic structures.
Symptoms
- Bruising or superficial trauma to the chest – S20
- Penetrating wounds and open injuries to thorax – S21
- Rib, sternum, or thoracic spine fractures – S22
- Joint dislocations and ligament sprains in thoracic region – S23
- Neurological deficits from thoracic spinal cord trauma – S24
- Vascular bleeding or damage to thoracic vessels – S25
- Blunt or penetrating cardiac injuries – S26
- Lung, esophageal, or mediastinal trauma – S27
- Crushing injuries and amputations involving thorax – S28
- Other thoracic injuries not specified elsewhere – S29
Diagnosis
Thoracic injuries are diagnosed using clinical examination, chest X-ray, CT scan, ultrasound (e.g., FAST exam), and echocardiography to detect fractures, bleeding, organ damage, or vascular injury.
ICD10 Code Usage
S27 is commonly used in emergency departments, trauma registries, cardiothoracic surgery, orthopedics, and billing systems to accurately classify and track thoracic injuries.

FAQs
Q1: What is ICD10 code S27?
A: It documents injuries involving the thorax, including the ribcage, heart, lungs, spine, and blood vessels.
Q2: How dangerous are thoracic injuries?
A: Thoracic trauma can be life-threatening if it involves major organs, vessels, or the spinal cord.
Q3: What imaging is preferred for chest injuries?
A: Chest X-rays and CT scans are most commonly used for rapid diagnosis.
Q4: How is a thoracic spinal cord injury identified?
A: MRI imaging and neurological examinations are key tools for diagnosing thoracic spinal cord injuries.
Q5: Can thoracic injuries cause long-term disability?
A: Yes, severe injuries to the spine, lungs, or heart may lead to chronic complications or disabilities.
Conclusion
ICD10 code S27 provides essential documentation for Injury of other and unspecified intrathoracic organs, ensuring proper clinical management, legal documentation, and insurance reporting of thoracic injuries.
