Code Description

ICD-10 S01.402 is a billable code used to indicate a diagnosis of unspecified open wound of left cheek and temporomandibular area.

Key Diagnostic Point:

The code S01.402 refers to an unspecified open wound located on the left cheek and temporomandibular area. This type of injury can occur due to various mechanisms, including blunt trauma, lacerations from sharp objects, or bites. The temporomandibular area is critical for jaw function, and injuries here can lead to complications such as pain, restricted movement, and potential damage to the underlying structures, including nerves and blood vessels. Clinical assessment typically involves a thorough physical examination to evaluate the extent of the wound, associated injuries, and any signs of infection. Imaging studies may be warranted to rule out fractures or deeper tissue damage. Management often includes wound cleaning, suturing if necessary, and monitoring for complications such as infection or scarring. The complexity of this injury lies in its potential impact on facial aesthetics and function, necessitating careful documentation and follow-up.

Complexity Factors

  • Variability in injury severity and type
  • Potential for associated fractures or deeper tissue damage
  • Need for multidisciplinary management (e.g., surgery, dentistry)
  • Documentation of wound characteristics and treatment

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the extent of the wound
  • Misclassification of the injury type
  • Lack of follow-up documentation
