Code Description

ICD-10 S02.109 is a billable code used to indicate a diagnosis of fracture of base of skull, unspecified side.

Key Diagnostic Point:

A fracture of the base of the skull is a serious injury that can occur due to high-impact trauma, such as motor vehicle accidents, falls from significant heights, or violent assaults. The base of the skull is the area that supports the brain and houses critical structures such as the brainstem and cranial nerves. Fractures in this area can lead to complications such as cerebrospinal fluid leaks, cranial nerve damage, and intracranial hemorrhage. Symptoms may include headache, confusion, loss of consciousness, and neurological deficits. Diagnosis typically involves imaging studies such as CT scans or MRIs to assess the extent of the fracture and any associated injuries. Management may require surgical intervention, especially if there is significant displacement or associated complications. The prognosis depends on the severity of the fracture and the presence of any additional injuries.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and symptoms
  • Need for imaging studies for accurate diagnosis
  • Potential for associated injuries complicating coding
  • Differentiation from other types of skull fractures

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the side of the fracture when applicable
  • Misclassification of fracture type
  • Lack of imaging documentation to support diagnosis
