Diagnosis Overview

What is Lumbar Foraminal Stenosis?
Essential facts and insights about Lumbar Foraminal Stenosis

Key Clinical Considerations:

  • Radicular pain in the lower extremities
  • Numbness or tingling in the legs
  • Weakness in the lower limbs
  • Key diagnostic tests include MRI or CT scans showing foraminal narrowing
  • Physical exam may reveal decreased reflexes, muscle weakness, or sensory deficits

Clinical Information

Clinical Criteria & Documentation Requirements

  • Document patient's history of symptoms and duration
  • Include imaging results and their interpretations
  • Use specific terms like 'lumbar foraminal stenosis' and 'radiculopathy'
  • Examples: 'Patient presents with bilateral leg pain and MRI shows L4-L5 foraminal stenosis.'

Coding Guidelines

Usage Guidelines & Examples

  • Usage guidelines: Use M48.06 for stenosis and M54.16 for associated radiculopathy.
  • Common errors: Misclassifying stenosis as general back pain (M54.9) instead of specific codes.

Code Exclusions

Important Exclusions

  • Excluded conditions: Spondylolisthesis, herniated discs.
  • Alternative codes: Consider M48.07 for other regions of spinal stenosis.
