Code Description

ICD-10 S31.04 is a billable code used to indicate a diagnosis of puncture wound with foreign body of lower back and pelvis.

Key Diagnostic Point:

A puncture wound with a foreign body in the lower back and pelvis is a specific type of injury that occurs when an object penetrates the skin and underlying tissues in these regions. This type of injury can result from various incidents, including accidents, falls, or assaults. The presence of a foreign body complicates the injury, as it may lead to infection, tissue damage, or further complications if not properly addressed. Clinically, patients may present with localized pain, swelling, and signs of infection such as redness or discharge. Imaging studies, such as X-rays or CT scans, may be necessary to locate the foreign object and assess any associated injuries to the lumbar spine, pelvic structures, or surrounding organs, including the genitourinary system. Emergency surgical intervention may be required to remove the foreign body, repair any damaged tissues, and prevent complications. The management of such injuries often involves a multidisciplinary approach, including trauma surgeons, urologists, and orthopedic specialists, depending on the extent of the injury and the structures involved.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Presence of foreign body complicates diagnosis and treatment.
  • Potential for associated injuries to lumbar spine and pelvic organs.
  • Need for imaging studies to determine the extent of injury.
  • Variability in clinical presentation based on the type of foreign body.

Audit Risk Factors

  • Inadequate documentation of the foreign body type and location.
  • Failure to document associated injuries or complications.
  • Lack of imaging reports to support the diagnosis.
  • Improper coding of related procedures performed during surgery.
