Code Description

ICD-10 S61.221 is a billable code used to indicate a diagnosis of laceration with foreign body of left index finger without damage to nail.

Key Diagnostic Point:

S61.221 describes a specific type of injury characterized by a laceration on the left index finger that is accompanied by a foreign body embedded in the wound, but without any damage to the nail. This condition often arises from accidents involving sharp objects, such as glass, metal, or wood, which can penetrate the skin and become lodged in the finger. The presence of a foreign body complicates the injury, as it may lead to infection, delayed healing, or further tissue damage if not properly addressed. Treatment typically involves careful removal of the foreign body, thorough cleaning of the wound, and possibly suturing to promote healing. The absence of nail damage is significant, as it indicates a lower risk of complications related to nail growth and integrity. Clinicians must assess for potential tendon or nerve involvement, as these structures can be affected by deep lacerations, necessitating further intervention or surgical repair. Accurate coding of this condition is essential for appropriate treatment planning and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Presence of foreign body complicates treatment and documentation.
  • Need for detailed clinical descriptions to differentiate from similar codes.
  • Potential for associated injuries (tendon, nerve) that may require additional coding.
  • Variability in documentation standards across specialties.

Audit Risk Factors

  • Inadequate documentation of the foreign body and its removal.
  • Failure to document the extent of the laceration.
  • Lack of follow-up notes regarding healing and complications.
  • Misclassification of the injury type or location.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of injuries, including the differentiation of lacerations with and without foreign bodies. This specificity improves the accuracy of medical records and enhances the ability to track injury patterns and outcomes.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of injuries, including the differentiation of lacerations with and without foreign bodies. This specificity improves the accuracy of medical records and enhances the ability to track injury patterns and outcomes.
