Code Description

ICD-10 M54.40 is a billable code used to indicate a diagnosis of lumbago with sciatica, unspecified side.

Key Diagnostic Point:

Lumbago with sciatica, unspecified side (M54.40) refers to a condition characterized by lower back pain (lumbago) accompanied by pain radiating down the leg(s) due to irritation or compression of the sciatic nerve. This condition can arise from various underlying causes, including herniated discs, spinal stenosis, or degenerative disc disease. Patients often present with symptoms such as sharp or shooting pain, numbness, or weakness in the affected leg, which may worsen with prolonged sitting or standing. The term 'unspecified side' indicates that the documentation does not specify whether the symptoms are unilateral or bilateral, which can complicate treatment planning. Management typically involves conservative approaches such as physical therapy, pain management, and lifestyle modifications. In more severe cases, surgical interventions like discectomy or laminectomy may be considered. Accurate coding is essential for proper reimbursement and to reflect the severity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Unspecified side may lead to ambiguity in treatment planning.
  • Differentiating between lumbago and other back pain conditions.
  • Need for comprehensive documentation to support the diagnosis.
  • Potential overlap with other codes related to sciatica.

Audit Risk Factors

  • Insufficient documentation of symptoms and their severity.
  • Failure to specify the side of sciatica when applicable.
  • Inadequate justification for conservative vs. surgical management.
  • Lack of follow-up documentation to support ongoing treatment.

Frequently Asked Questions

What is the difference between M54.40 and M54.41?

M54.40 is used when the side of sciatica is unspecified, while M54.41 is used when sciatica is present on the right side. Accurate coding requires documentation of the side affected.
