CPT® Code 63285

The procedure described by CPT® Code 63285 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm that is located intradurally and intramedullarily within the cervical region of the spinal cord. An intraspinal neoplasm refers to a tumor that can be benign, malignant, or of uncertain behavior, and is situated within the protective dura mater surrounding the spinal cord. This procedure is critical for diagnosing and treating tumors that may affect spinal cord function. During the laminectomy, an incision is made in the skin over the cervical area, allowing access to the spine. The surgical approach requires careful retraction of muscle and removal of bone to expose the spinal cord and the tumor. The tumor is then accessed through an incision in the dura mater, and a biopsy may be taken for pathological examination. If the tumor is deemed excisable, it is meticulously dissected from surrounding tissues using an operating microscope to ensure complete removal while preserving spinal cord integrity. The procedure concludes with the closure of the dura mater, which may involve sutures or a dural patch graft to ensure proper healing and protection of the spinal cord.
