M43.5X5
ICD-10-CMThis code signifies a condition where vertebrae in the thoracolumbar spine (the junction between the thoracic and lumbar regions) repeatedly slip out of their normal alignment. This dislocation is not due to a fracture and is considered "other" to differentiate it from congenital or traumatic types. It implies an instability that leads to recurrent episodes of vertebral displacement.
Apply this code when documentation clearly indicates a diagnosis of recurrent vertebral dislocation specifically affecting the thoracolumbar region. This diagnosis should be made by a physician and supported by imaging studies (e.g., X-ray, MRI) confirming the instability and recurrent nature of the dislocation. It is appropriate for patients experiencing repeated episodes of pain, neurological symptoms, or functional limitations due to this instability.
