Neuromuscular scoliosis, thoracic region

This code identifies a spinal curvature (scoliosis) in the thoracic region that is directly caused by an underlying neuromuscular disorder. This type of scoliosis is often progressive and can be associated with conditions affecting muscle control and strength, such as cerebral palsy, muscular dystrophy, or spinal muscular atrophy.

Assign this code when documentation explicitly links thoracic scoliosis to a primary neuromuscular condition. This typically applies to patients with known neurological or muscular diseases who develop a C-shaped or S-shaped spinal curve in the mid-back. Supporting documentation should include a definitive diagnosis of the neuromuscular disorder and a clear statement indicating its causative role in the scoliosis.

• Always sequence the underlying neuromuscular disorder code first, as it is the etiology.
• Ensure the documentation specifies the thoracic region; codes exist for other spinal regions (e.g., lumbar, cervicothoracic).
• Distinguish from idiopathic scoliosis (M41.1-) or congenital scoliosis (Q67.5), which have different etiologies.
