M41.84
ICD-10-CMThis code identifies a non-specific type of lateral curvature of the spine affecting the thoracic region, not classified as congenital, neuromuscular, or idiopathic. It encompasses various less common or ill-defined forms of scoliosis localized to the mid-back.
Apply this code when documentation specifies scoliosis in the thoracic spine that doesn't fit into more specific categories like congenital (Q67.5), neuromuscular (G80.x, G81.x), or adolescent idiopathic (M41.12-). This is often used when the etiology is unknown or described vaguely as "other" or "secondary" without further specification.
