Summary & Overview
CPT 63285: Cervical Intradural Intramedullary Lesion Excision
CPT code 63285 represents a complex neurosurgical procedure: removal of a portion of a cervical lamina and excision of an intradural, intramedullary spinal cord lesion with tissue submitted for pathology. This code captures high-acuity, technically demanding interventions on the cervical spinal cord and is relevant to national discussions about surgical resource utilization, perioperative risk, and appropriate hospital-level care. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of clinical context (indications and typical operative setting), payer coverage patterns and benchmarks where available, and coding considerations that affect service-line reporting and facility billing. The publication highlights national implications for surgical services and hospital throughput, reimbursement variability among major payers, and areas where policy updates or utilization review commonly arise. Data not available in the input is noted where applicable; the piece focuses on providing clear definitions, typical site-of-service expectations, and what stakeholders should consider when encountering CPT code 63285 in claims and clinical documentation.
Billing Code Overview
CPT code 63285 describes a surgical procedure in which a surgeon removes part of the cervical vertebral lamina and excises an intradural, intramedullary spinal cord lesion, with submission of a portion of the lesion for pathological testing. Intradural indicates the lesion is located inside the dura mater; intramedullary indicates the lesion is within the spinal cord substance itself.
Service type: Surgical excision of intradural intramedullary spinal cord lesion with laminectomy/laminotomy
Typical site of service: Hospital inpatient or outpatient surgical center, operating room
Clinical & Coding Specifications
Clinical Context
A 48-year-old patient presents with progressive cervical myelopathic symptoms including hand weakness, gait instability, and sensory changes. MRI of the cervical spine demonstrates an enhancing intradural, intramedullary lesion at the C4–C5 level consistent with a spinal cord tumor such as an ependymoma or astrocytoma. After multidisciplinary review, the neurosurgeon schedules an operative intervention: a posterior cervical laminectomy with microsurgical intradural myelotomy and partial resection of the intramedullary lesion with tissue sent for frozen section and permanent pathology.
Preoperative workflow includes neurologic examination, cervical spine imaging (MRI with and without contrast), baseline labs, anesthesiology evaluation, and informed consent that documents risks of cord manipulation. Intraoperative steps include patient positioning prone, posterior midline exposure, removal of the lamina (laminectomy) at the affected level, durotomy, microsurgical dissection of the intramedullary tumor, biopsy or partial resection with hemostasis, dural closure, and multilayer wound closure. Postoperative care involves ICU or step-down monitoring for neurologic status, pain control, imaging as indicated, and coordination with pathology for diagnosis and oncology for adjuvant therapy if needed.
