Code Description

ICD-10 S31.133 is a billable code used to indicate a diagnosis of puncture wound of abdominal wall without foreign body, right lower quadrant without penetration into peritoneal cavity.

Key Diagnostic Point:

A puncture wound of the abdominal wall in the right lower quadrant is characterized by a breach in the skin and underlying tissues without the introduction of a foreign body and without penetration into the peritoneal cavity. This type of injury may occur due to various mechanisms, including accidental trauma from sharp objects or intentional injuries. Clinically, patients may present with localized pain, swelling, and tenderness in the right lower quadrant, but without signs of peritoneal irritation such as rebound tenderness or guarding. Diagnostic imaging may be warranted to rule out deeper organ injury, particularly to the appendix or other structures in the right lower quadrant. Management typically involves wound care, monitoring for infection, and ensuring that no underlying organ injury has occurred. Surgical intervention is rarely required unless complications arise, such as abscess formation or if there is a concern for deeper tissue involvement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between types of abdominal wall injuries
  • Understanding the implications of non-penetrating versus penetrating wounds
  • Identifying associated injuries in the right lower quadrant
  • Documenting the absence of foreign bodies accurately

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the absence of foreign bodies
  • Misclassification of the injury type
  • Lack of follow-up documentation for potential complications

Frequently Asked Questions

What is the difference between S31.133 and S31.134?

S31.133 refers to a puncture wound without penetration into the peritoneal cavity, while S31.134 indicates a puncture wound that does penetrate the peritoneal cavity, which may require different management and coding.
