M41.86
ICD-10-CMThis code identifies a type of spinal curvature that is not congenital, neuromuscular, or idiopathic, specifically affecting the lumbar spine. It encompasses various less common or atypical forms of scoliosis localized to the lower back. This diagnosis indicates a lateral deviation of the vertebral column in the lumbar region due to causes other than those classified elsewhere.
Use this code when documentation specifies scoliosis in the lumbar region that does not fit into categories such as congenital, neuromuscular, or adolescent idiopathic scoliosis. This applies to cases where the etiology is described as "other" or unspecified but clearly impacts the lumbar spine. Supporting documentation should clearly state the affected spinal region and rule out more specific forms of scoliosis.
