Code Description

ICD-10 M41.126 is a billable code used to indicate a diagnosis of adolescent idiopathic scoliosis, lumbar region.

Key Diagnostic Point:

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity characterized by lateral curvature of the spine, typically occurring during the growth spurt just before puberty. The lumbar region is specifically affected in this code, indicating that the curvature is primarily located in the lower back. The etiology of AIS remains largely unknown, although genetic factors and environmental influences may play a role. Clinically, patients may present with asymmetry in shoulder height, rib prominence, and waistline irregularities. Diagnosis is confirmed through physical examination and imaging studies, such as X-rays, which reveal the degree of curvature measured in degrees using the Cobb angle. Treatment options vary based on the severity of the curvature and the patient's age, ranging from observation and bracing to surgical interventions like spinal fusion. Early detection and management are crucial to prevent progression and associated complications, including pain and impaired function.

Frequently Asked Questions

What is the significance of the Cobb angle in scoliosis?

The Cobb angle is a critical measurement used to assess the severity of scoliosis. It helps determine the need for treatment and the potential for progression of the curvature.
