Summary & Overview
CPT 63011: Laminectomy of One or Two Sacral Segments
CPT code 63011 identifies a laminectomy targeting one or two sacral vertebral segments performed to explore and/or decompress the spinal cord and/or cauda equina. This focused posterior decompression is distinct because it explicitly excludes facetectomy, foraminotomy, and discectomy. As a surgical spine code, 63011 matters nationally due to its role in treating severe neural compression syndromes that can affect mobility, bladder and bowel function, and pain management, and because it has implications for surgical resource use and facility planning.
Key payers in national coverage of this procedure include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context and typical sites of service, plus benchmarking and policy-oriented content where available. The publication highlights expected utilization patterns, coding distinctions from related spinal procedures, and payer coverage considerations. When payer-specific benchmarks or policy updates are present, the report summarizes those trends and any notable national policy guidance affecting surgical spine care.
Data not available in the input for associated taxonomies, specific ICD-10 diagnoses tied to billing, and payer-specific fee benchmarks. The report focuses on clinical definition, coding boundaries, typical care settings, and the areas where payers and policy intersect for this procedure.
Billing Code Overview
CPT code 63011 describes a laminectomy of one or two sacral vertebral segments with exploration and/or decompression of the spinal cord and/or cauda equina. The description specifies that the procedure does not include a facetectomy, foraminotomy, or discectomy.
-
Service type: Surgical spinal decompression procedure involving posterior removal of lamina at one or two sacral levels to explore and/or decompress neural elements.
-
Typical site of service: Hospital inpatient or outpatient surgical setting or ambulatory surgery center, depending on clinical severity and facility resources.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents with progressive lower extremity weakness, saddle anesthesia, and worsening neurogenic claudication after conservative care (physical therapy, analgesics) failed. MRI shows central canal stenosis at the sacral segments with compression of the cauda equina. The neurosurgery team schedules a laminectomy of one sacral vertebral segment to decompress the cauda equina. Preoperative workflow includes history and physical, informed consent, anesthesia evaluation, and surgical planning with imaging review. Operative care involves general anesthesia, prone positioning, a midline sacral incision, removal of the lamina for one sacral level without facetectomy, foraminotomy, or discectomy, hemostasis, and layered closure. Postoperative care includes neurologic checks, pain control, wound care, physical therapy as indicated, and discharge planning with follow-up for wound check and neurologic assessment.
