Code Description

ICD-10 G83.4 is a billable code used to indicate a diagnosis of cauda equina syndrome.

Key Diagnostic Point:

Cauda equina syndrome (CES) is a serious neurological condition that occurs when the cauda equina, a bundle of spinal nerves located at the lower end of the spinal cord, becomes compressed. This compression can lead to a variety of symptoms, including severe lower back pain, loss of sensation in the legs, bowel and bladder dysfunction, and motor weakness. The condition can result from various causes, including herniated discs, spinal stenosis, tumors, or trauma. Prompt diagnosis and treatment are critical, as untreated CES can lead to permanent paralysis, loss of bladder and bowel control, and other significant mobility impairments. Patients may experience varying degrees of paralysis, including paraplegia (loss of function in the lower limbs) or quadriplegia (loss of function in all four limbs), depending on the severity and location of the nerve compression. The management of CES often involves surgical intervention to relieve pressure on the nerves, followed by rehabilitation to address mobility impairments and improve quality of life.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Variety of underlying causes leading to CES
  • Potential for co-existing conditions affecting mobility
  • Need for detailed documentation of neurological deficits
  • Variability in clinical presentation among patients

Audit Risk Factors

  • Inadequate documentation of neurological examination findings
  • Failure to specify the cause of cauda equina syndrome
  • Lack of evidence for surgical intervention or treatment plan
  • Misclassification of severity of paralysis or mobility impairment

Specialty Focus

Neurology

Documentation Requirements

Detailed neurological examination findings, including motor and sensory assessments, and imaging results.

Common Clinical Scenarios

Patients presenting with acute lower back pain and neurological deficits, requiring urgent evaluation.

Billing Considerations

Ensure clear documentation of the onset of symptoms and any interventions performed.

Orthopedic Surgery

Documentation Requirements

Surgical notes detailing the procedure performed to relieve nerve compression and post-operative assessments.

Common Clinical Scenarios

Patients undergoing decompression surgery for herniated discs or spinal stenosis leading to CES.

Billing Considerations

Document the rationale for surgical intervention and any pre-existing mobility impairments.

Coding Guidelines

Inclusion Criteria

Use G83.4 When
  • According to ICD
  • 10 coding guidelines, G83
  • 4 should be used when there is clear documentation of cauda equina syndrome with specific neurological deficits

Exclusion Criteria

Frequently Asked Questions

What are the common causes of cauda equina syndrome?

Common causes include herniated discs, spinal stenosis, tumors, and trauma. Each cause can lead to varying degrees of nerve compression and associated symptoms.

How is cauda equina syndrome diagnosed?

Diagnosis typically involves a thorough clinical examination, assessment of neurological function, and imaging studies such as MRI or CT scans to visualize nerve compression.

What are the treatment options for cauda equina syndrome?

Treatment often involves surgical intervention to relieve pressure on the cauda equina, followed by rehabilitation to address mobility impairments and restore function.
