Juvenile idiopathic scoliosis, site unspecified

This code signifies a lateral curvature of the spine that develops before the age of 10, without an identifiable underlying cause such as congenital anomalies, neuromuscular disorders, or trauma. It is a diagnosis of exclusion, indicating that other forms of scoliosis have been ruled out. The "site unspecified" indicates that the specific region of the spine affected (e.g., thoracic, lumbar) is not documented.

Use this code when documentation confirms a diagnosis of idiopathic scoliosis in a patient under 10 years old, and the specific spinal region involved is not specified. This typically occurs when the initial diagnosis is made, or if the provider's documentation does not detail the exact location of the curvature. Supporting documentation includes physician notes detailing the age of onset and ruling out secondary causes.

• Ensure the patient's age at diagnosis is clearly documented as under 10 years to differentiate from adolescent idiopathic scoliosis (M41.12-).
• Avoid using this code if the specific site of the scoliosis (e.g., thoracic, lumbar) is known and documented; instead, select a more specific code from the M41.11- series.
• Confirm that no underlying cause for the scoliosis is identified, as this is a diagnosis of exclusion.
