Code Description

ICD-10 S61.002 is a billable code used to indicate a diagnosis of unspecified open wound of left thumb without damage to nail.

Key Diagnostic Point:

An unspecified open wound of the left thumb without damage to the nail indicates a traumatic injury where the skin is broken, exposing underlying tissues but not affecting the nail structure. This type of injury can occur due to various mechanisms, such as lacerations from sharp objects, punctures, or abrasions. The clinical presentation may include bleeding, pain, swelling, and potential contamination of the wound. Proper assessment is crucial to determine the extent of injury, which may involve evaluating for associated conditions such as tendon injuries, fractures, or nerve damage. Treatment typically involves cleaning the wound, possibly suturing, and monitoring for infection. In some cases, surgical intervention may be necessary if deeper structures are involved. Accurate coding is essential for appropriate reimbursement and to reflect the severity of the injury in medical records.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of wound depth and extent
  • Potential for associated injuries (e.g., fractures, tendon damage)
  • Need for precise anatomical localization
  • Differentiation from similar codes for other finger injuries

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the depth of the wound
  • Lack of follow-up documentation on healing or complications
  • Misclassification of the wound type
