Summary & Overview
CPT 63056: Transpedicular Lumbar Discectomy
CPT code 63056 denotes a transpedicular surgical approach to repair a bulging lumbar intervertebral disc without direct manipulation of the spinal cord. This targeted decompression procedure is used to relieve pressure on the spinal cord, cauda equina, or nerve roots and is clinically relevant for patients with radiculopathy or neurocompression originating from a posterior-lateral lumbar disc. Nationally, the code is important for surgical practice patterns, site-of-service planning, and payer coverage policies for spinal decompression techniques.
Key payers in this context include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical intent and service settings, typical billing and documentation considerations, and the payer landscape most likely to impact coverage and reimbursement determinations. The publication provides benchmarks and policy context relevant to utilization of coded transpedicular lumbar discectomy, highlights coding specificity for approach and anatomical target, and summarizes implications for facility and professional claims. Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.
Billing Code Overview
CPT code 63056 describes a surgical procedure using a transpedicular approach to repair a bulging lumbar intervertebral disc without manipulating the spinal cord. The procedure is performed through the side of the pedicle of a lumbar vertebra to remove or decompress disc material compressing neural structures.
Service Type
- Surgical decompression / discectomy via transpedicular approach
Typical Site of Service
- Hospital operating room
- Ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents with a 6-week history of progressively worsening right-sided radicular lower extremity pain, numbness in the L4 distribution, and limited ambulation despite conservative management including physical therapy, oral analgesics, and epidural steroid injection. MRI of the lumbar spine demonstrates a posterolateral transpedicular herniation at L4-L5 causing compression of the L4 nerve root. Neurological exam shows decreased right ankle reflex and weakness in ankle dorsiflexion. After preoperative evaluation and informed consent, the patient is brought to an outpatient ambulatory surgery center or hospital operating room. Under general anesthesia, the spine surgeon performs a transpedicular microdiscectomy via a lateral transpedicular approach to remove the herniated nucleus pulposus and decompress the affected nerve root without direct manipulation of the spinal cord. Intraoperative fluoroscopy is used to localize the pedicle, and standard sterile technique is followed. Postoperative care includes monitoring in the PACU, multimodal analgesia, mobilization next day, and wound checks with follow-up in clinic for neurologic assessment and activity progression.
