Understanding Head Injuries in ICD-10
Head injuries encompass a broad spectrum of trauma affecting the skull, scalp, brain, and associated structures. In ICD-10, head injuries are categorized under the broader classification of injuries of the head, with specific codes assigned based on the nature, severity, and location of the injury. Proper understanding and application of these codes facilitate accurate documentation and effective management.

Classification of Head Injuries in ICD-10
ICD-10 classifies head injuries primarily into traumatic brain injuries (TBIs) and skull injuries, with further subdivisions based on severity and specific features.
1. Traumatic Brain Injury (TBI)
Traumatic brain injuries are injuries that result from external mechanical force causing brain dysfunction. In ICD-10, TBIs are categorized under codes S06, which cover various types of intracranial injuries.
Key subcategories include:
- S06.0 – Concussion
- S06.1 – Diffuse traumatic brain injury
- S06.2 – Focal traumatic brain injury
- S06.3 – Epidural hemorrhage
- S06.4 – Subdural hemorrhage
- S06.5 – Intracerebral hemorrhage
- S06.6 – Traumatic subarachnoid hemorrhage
- S06.7 – Other specified intracranial injuries
- S06.8 – Other intracranial injuries
- S06.9 – Unspecified intracranial injury
Note: The classification allows clinicians to specify the precise nature of the brain injury, which is crucial for prognosis and treatment.
2. Skull Fractures
Skull fractures are classified under the code S02, with further differentiation based on the type and location of the fracture.
Key subcategories include:
- S02.0 – Fracture of vault of skull
- S02.1 – Fracture of base of skull
- S02.2 – Multiple fractures of skull
- S02.3 – Other and unspecified skull fractures
Additional details:
- Open vs. closed fractures
- Comminuted fractures
- Depressed fractures
3. Scalp Injuries
While less severe, scalp injuries are also coded under S00-S09, depending on the severity and specific region.

Key ICD-10 Codes for Head Injuries
Accurate coding requires detailed documentation of the injury type, location, and severity. Below are some common ICD-10 codes associated with head injuries:
- Concussion (S06.0): Mild traumatic brain injury characterized by transient neurological dysfunction.
- Contusion of brain (S06.2): Bruising of brain tissue, often associated with focal neurological deficits.
- Epidural hemorrhage (S06.3): Bleeding between the dura mater and skull.
- Subdural hemorrhage (S06.4): Bleeding beneath the dura mater, often following tearing of bridging veins.
- Skull fracture, vault (S02.0): Fractures involving the cranial vault.
- Skull fracture, base (S02.1): Fractures involving the bones at the base of the skull, often associated with CSF leaks or cranial nerve injury.

Clinical Features and Severity of Head Injuries
Head injuries vary widely in presentation, from minor bumps to life-threatening trauma. The ICD-10 classification reflects this diversity, aiding clinicians in diagnosis and management.
1. Mild Head Injuries
- Often involve concussion
- Symptoms: brief loss of consciousness, confusion, headache, dizziness
- Usually do not involve structural brain damage
2. Moderate Head Injuries
- May involve brief loss of consciousness
- Symptoms: persistent headache, vomiting, amnesia
- Possible intracranial hemorrhages
3. Severe Head Injuries
- Prolonged unconsciousness or coma
- Significant neurological deficits
- Risk of death or permanent disability

Diagnosis and Evaluation
Diagnosis of head injuries involves a combination of clinical assessment and imaging studies.
1. Clinical Examination
- Glasgow Coma Scale (GCS) assessment
- Neurological examination
- Assessment of signs such as pupillary response, motor function, and signs of skull fracture
2. Imaging Modalities
- Computed Tomography (CT) scan: Primary modality for detecting intracranial hemorrhages, skull fractures, and brain contusions
- Magnetic Resonance Imaging (MRI): Used for detailed brain tissue assessment, especially in subacute or chronic phases
---
Management and Treatment of Head Injuries
The treatment approach depends on injury severity and type.
1. Conservative Management
- Observation
- Rest
- Analgesics
- Monitoring neurological status
2. Surgical Intervention
- Evacuation of hematomas
- Fracture repair
- CSF leak repair
3. Rehabilitation
- Physical therapy
- Cognitive therapy
- Psychosocial support
---
Prevention of Head Injuries
Preventive measures are crucial in reducing the incidence and severity of head injuries.
Strategies include:
- Wearing helmets during high-risk activities
- Use of seat belts and child restraints
- Fall prevention in the elderly
- Safety regulations in workplaces
- Public awareness campaigns
---
Legal and Coding Guidelines for Head Injuries
Accurate ICD-10 coding is vital for legal documentation, insurance claims, and health statistics.
1. Documentation Requirements
- Precise description of injury type, location, and severity
- Imaging findings
- Treatment administered
2. Coding Tips
- Use the most specific code available
- Combine injury codes with external cause codes for context
- Follow national or institutional coding guidelines
3. Common Pitfalls to Avoid
- Under-coding or over-coding
- Ignoring injury severity
- Using unspecified codes when more precise codes are available

Conclusion
Injury of head ICD 10 encompasses a broad range of traumatic injuries affecting the skull and brain. Proper classification and coding are essential for effective clinical management, accurate data collection, and insurance processing. Recognizing the various types of head injuries—such as concussions, intracranial hemorrhages, and skull fractures—and understanding their clinical implications enable healthcare professionals to deliver appropriate care. Moreover, preventive strategies play a critical role in reducing the burden of head injuries worldwide. As medical technology and coding systems evolve, continuous education and adherence to guidelines will ensure optimal patient outcomes and reliable health data.

Frequently Asked Questions
What are the most common ICD-10 codes used for head injuries?
Common ICD-10 codes for head injuries include S06.0 (Concussion), S06.5 (Traumatic subdural hemorrhage), S06.3 (Epidural hemorrhage), and S06.2 (Diffuse brain injury).
How is a concussion classified in ICD-10 coding?
A concussion is classified under ICD-10 code S06.0, which specifies a concussion of the brain resulting from head injury.
What ICD-10 code should be used for skull fractures resulting from head trauma?
Skull fractures are coded as S02.0 (Fracture of skull) or S02.1 (Multiple fractures of skull), depending on the specific injury details.
Are there specific ICD-10 codes for minor versus severe head injuries?
Yes, minor head injuries like concussion are coded under S06.0, while more severe injuries such as intracranial hemorrhages have codes like S06.5 or S06.3, indicating increased severity.
How does ICD-10 differentiate between open and closed head injuries?
ICD-10 codes differentiate open versus closed head injuries based on specific codes; for example, S06.2 refers to diffuse brain injury (closed), while S06.5 indicates traumatic subdural hemorrhage, which can be open or closed depending on the injury specifics.
