CPT® Code 63015

Laminectomy with exploration and/or decompression of spinal cord and/or cauda equina, without facetectomy, foraminotomy or discectomy (eg, spinal stenosis), more than 2 vertebral segments; cervical

Laminectomy, specifically referred to in CPT® Code 63015, is a surgical procedure that involves the excision of the lamina, which is the bony structure forming the posterior aspect of the vertebral arch. This procedure is primarily performed to investigate the underlying causes of back pain and to alleviate pressure on critical structures such as the spinal cord, spinal nerve roots, and/or cauda equina. The surgical approach typically begins with a posterior skin incision made over the affected area of the spine, allowing access to the lamina. Once the incision is made, the overlying fat and muscle tissues are carefully retracted to expose the lamina. The excision of the lamina is followed by the removal of the paired ligaments, known as the ligamentum flavum, which connect the laminae of adjacent vertebrae. This step is crucial as it allows for the exposure and exploration of the spinal canal. During the procedure, any adhesions that may have formed between the dura mater and the ligamentum flavum are lysed, facilitating a clearer view and access to the spinal nerve roots and cauda equina. The procedure is specifically indicated for cases involving more than two contiguous vertebral segments in the cervical region. If stabilization of the spine is necessary, a separate arthrodesis may be performed. It is important to note that laminectomy procedures are categorized based on the spinal region, with specific codes assigned for more than two vertebral segments in the cervical, thoracic, and lumbar regions, respectively.
