Code Description

ICD-10 M54.42 is a billable code used to indicate a diagnosis of lumbago with sciatica, left side.

Key Diagnostic Point:

Lumbago with sciatica, left side (M54.42) refers to lower back pain (lumbago) that is accompanied by pain radiating down the left leg due to irritation or compression of the sciatic nerve. This condition often arises from various underlying causes, including herniated discs, spinal stenosis, or degenerative disc disease. Patients typically present with symptoms such as sharp or shooting pain, numbness, or weakness in the left leg, which may be exacerbated by prolonged sitting, standing, or certain movements. Diagnosis is primarily clinical, supported by imaging studies like MRI or CT scans when necessary. Treatment options vary and can include conservative management such as physical therapy, medications (NSAIDs, muscle relaxants), and lifestyle modifications. In cases where conservative measures fail, surgical interventions like discectomy or laminectomy may be considered. Understanding the nuances of this condition is crucial for accurate coding and effective patient management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between lumbago and other types of back pain
  • Identifying the specific side of sciatica
  • Understanding the underlying causes of sciatica
  • Documenting the severity and duration of symptoms

Audit Risk Factors

  • Inadequate documentation of the side affected
  • Failure to specify the underlying cause of sciatica
  • Misclassification of the type of back pain
  • Lack of evidence for conservative treatment attempts
