Summary & Overview
CPT 63277: Lumbar Extradural Lesion Excision with Vertebral Resection
CPT code 63277 represents a spinal surgical procedure involving removal of part of a lumbar vertebra (laminectomy or partial vertebral resection) and excision of an extradural spinal lesion with tissue sent for pathologic analysis. Nationally, this code matters because it captures a high-complexity operative spine intervention that intersects neurosurgery and orthopedic spine practice and has implications for inpatient resource use, surgical complication coding, and specialist reimbursement. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context of the procedure, the typical sites of service where it is performed, and how this service is represented in billing. The publication provides benchmarks and comparative guidance on coding practices, documentation elements tied to lesion excision and specimen submission, and policy-relevant notes for major national payers. It also outlines common clinical indications and procedural components that affect coding specificity and potential audit focus. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 63277 describes a surgical procedure in which the provider removes a portion of a lumbar vertebra and excises an extradural growth of the spinal cord, with a portion of the lesion sent for pathologic testing. Extradural indicates the lesion is located outside the dura, the tough outer membrane surrounding the central nervous system.
Service Type: Surgical – spinal decompression and lesion excision
Typical Site of Service: Inpatient or outpatient hospital operating room; specialized surgical center for spine procedures

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with progressive lower back pain, radicular symptoms to the lower extremity, and imaging that identifies an extradural lumbar spinal mass causing neural compression. The neurosurgical team evaluates neurologic deficits, reviews MRI showing an extradural lesion at L2–L4 with foraminal extension, and recommends surgical decompression with partial laminectomy and excision of the extradural growth. Preoperative workup includes history and physical, anesthesia evaluation, baseline labs, and informed consent for possible intraoperative biopsy and frozen section. In the operating room under general anesthesia, the surgeon performs a partial lumbar vertebral removal (laminotomy/laminectomy as indicated), identifies and excises the extradural lesion, and sends a portion of the specimen for pathologic evaluation. Postoperative workflow includes immediate recovery monitoring, pain control, neurologic checks, wound care instructions, and coordination of pathology results to guide further oncologic or infectious disease management if required.
