Other idiopathic scoliosis, lumbar region

This code signifies a curvature of the spine in the lumbar region (lower back) that is not attributable to a known cause (idiopathic). It represents a non-specific form of idiopathic scoliosis affecting only the lower back, distinct from congenital, neuromuscular, or other secondary forms.

Use this code when documentation specifies idiopathic scoliosis localized to the lumbar spine, without further specification of type (e.g., infantile, juvenile, adolescent). Supporting documentation should clearly indicate the lumbar region as the primary or sole affected area and rule out other etiologies for the spinal curvature.

• Ensure documentation explicitly states "idiopathic" and specifies the "lumbar region" to avoid miscoding.
• Do not use this code if the scoliosis extends into other spinal regions (e.g., thoracolumbar, thoracic); use a more specific code.
• Always review for laterality if specified, though not applicable to this particular code, it's a general scoliosis coding consideration.
