Code Description

ICD-10 S02.651 is a billable code used to indicate a diagnosis of fracture of angle of right mandible.

Key Diagnostic Point:

The fracture of the angle of the right mandible refers to a break in the bone at the posterior aspect of the mandible, where the vertical ramus meets the horizontal body of the mandible. This type of fracture is commonly associated with trauma, such as motor vehicle accidents, physical assaults, or falls. The angle of the mandible is a critical area as it supports the lower jaw and is involved in mastication and speech. Clinical presentation may include pain, swelling, and difficulty in opening the mouth (trismus). Diagnosis typically involves a thorough clinical examination and imaging studies, such as X-rays or CT scans, to assess the fracture's location and severity. Management may include conservative treatment with pain control and dietary modifications or surgical intervention, such as open reduction and internal fixation, depending on the fracture's complexity and displacement. Complications can include malunion, nonunion, or infection, particularly if surgical intervention is required. Accurate coding is essential for proper reimbursement and tracking of injury patterns.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in fracture types and locations
  • Need for precise documentation of injury mechanism
  • Potential for associated injuries in polytrauma cases
  • Differentiation from other mandibular fractures

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify laterality or fracture type
  • Misclassification of fracture severity
  • Inconsistent coding of associated injuries

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Documentation must include a detailed account of the mechanism of injury, clinical findings, and any imaging results.

Common Clinical Scenarios

Patients presenting with facial trauma from accidents or assaults requiring immediate assessment and imaging.

Billing Considerations

Ensure that all relevant injuries are documented to support coding for multiple trauma cases.

Surgery

Documentation Requirements

Operative reports must detail the surgical approach, fixation methods, and any complications encountered during the procedure.

Common Clinical Scenarios

Surgical management of displaced fractures requiring open reduction and internal fixation.

Billing Considerations

Accurate coding of surgical procedures must align with the diagnosis to avoid discrepancies.

Coding Guidelines

Inclusion Criteria
