Code Description

ICD-10 M41.04 is a billable code used to indicate a diagnosis of infantile idiopathic scoliosis, thoracic region.

Key Diagnostic Point:

Infantile idiopathic scoliosis is a spinal deformity characterized by an abnormal lateral curvature of the spine that occurs in children under the age of three. This condition is classified as idiopathic, meaning the exact cause is unknown, although it is believed to involve a combination of genetic and environmental factors. The thoracic region is specifically affected, leading to a curvature that can impact respiratory function and overall physical development. Diagnosis typically involves clinical examination and imaging studies such as X-rays to assess the degree of curvature. Treatment options vary based on the severity of the curvature and may include observation, bracing, or surgical intervention. Surgical options often involve spinal fusion procedures to correct the curvature and stabilize the spine, particularly in cases where the curvature is progressive or severe. Early detection and intervention are crucial to prevent complications and improve outcomes for affected children.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of scoliosis in infants
  • Need for precise imaging documentation
  • Differentiation from other types of scoliosis
  • Potential for associated conditions affecting coding

Audit Risk Factors

  • Inadequate documentation of curvature measurements
  • Failure to specify the thoracic region
  • Misclassification of idiopathic versus secondary scoliosis
  • Lack of follow-up documentation on treatment outcomes

Specialty Focus

Frequently Asked Questions

What is the primary treatment for infantile idiopathic scoliosis?

The primary treatment for infantile idiopathic scoliosis depends on the severity of the curvature. Mild cases may be monitored, while moderate to severe cases may require bracing or surgical intervention, such as spinal fusion, to correct the curvature and prevent complications.
