Code Description

ICD-10 G57.23 is a billable code used to indicate a diagnosis of lesion of femoral nerve, bilateral lower limbs.

Key Diagnostic Point:

The femoral nerve is responsible for innervating the anterior compartment of the thigh, which includes the quadriceps muscle, and plays a crucial role in knee extension and hip flexion. A lesion of the femoral nerve can result from various causes, including trauma, compression, or systemic diseases such as diabetes mellitus. Patients may present with symptoms such as weakness in knee extension, sensory loss in the anterior thigh and medial aspect of the leg, and difficulty in ambulation. Bilateral involvement suggests a more systemic or widespread issue, potentially indicating conditions like bilateral nerve entrapment syndromes or neuropathies. Diagnosis typically involves a thorough clinical examination, nerve conduction studies, and imaging to identify the underlying cause of the nerve lesion. Treatment may include physical therapy, pain management, and addressing the underlying condition causing the nerve damage. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Bilateral involvement complicates the clinical picture.
  • Differentiating between various causes of nerve lesions.
  • Need for comprehensive documentation of symptoms and diagnostic tests.
  • Potential overlap with other neuropathies and nerve entrapments.

Audit Risk Factors

  • Inadequate documentation of bilateral symptoms.
  • Failure to specify the underlying cause of the nerve lesion.
  • Misinterpretation of nerve conduction study results.
  • Lack of clarity in the clinical rationale for the diagnosis.
