Code Description

ICD-10 M43.01 is a billable code used to indicate a diagnosis of spondylolysis, occipito-atlanto-axial region.

Key Diagnostic Point:

Spondylolysis in the occipito-atlanto-axial region refers to a defect or fracture in the bony arch of the vertebrae located at the junction of the skull and the first two cervical vertebrae (the atlas and axis). This condition can lead to instability in the cervical spine, resulting in pain, neurological deficits, or other complications. Spondylolysis may be caused by congenital factors, trauma, or repetitive stress. Patients often present with neck pain, limited range of motion, and may experience headaches or neurological symptoms if the spinal cord or nerve roots are affected. Diagnosis typically involves imaging studies such as X-rays, CT scans, or MRIs to visualize the defect and assess any associated spinal deformities. Treatment options may include conservative management with physical therapy and pain management, or surgical intervention in cases of significant instability or neurological compromise. Understanding the implications of spondylolysis in this region is crucial for effective management and coding.
