Summary & Overview
HCPCS Level II S2350: Anterior Lumbar Diskectomy with Decompression
HCPCS Level II code S2350 represents an anterior lumbar diskectomy with decompression of the spinal cord and/or nerve roots, including osteophytectomy at a single interspace. This surgical code captures a common spine procedure intended to relieve nerve compression and associated radiculopathy or myelopathy. Nationally, accurate coding for this service affects hospital and surgical facility billing, utilization tracking, and coverage determinations for spine surgery.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise overview of clinical context for the procedure, typical sites of service, and how the code is applied in facility billing. The publication outlines common benchmarking items and policy-relevant topics that influence coverage and payment, such as site-of-service variations and documentation needed to support medical necessity.
This report provides: a clear clinical description of the service captured by S2350; guidance on where the procedure is typically performed; and a summary of payer coverage considerations and benchmarking topics. Data not available in the input are noted where applicable.
Billing Code Overview
HCPCS Level II code S2350 describes a diskectomy, anterior, with decompression of spinal cord and/or nerve root(s), including osteophytectomy; lumbar, single interspace. This procedure involves anterior access to the lumbar spine to remove disc material and bony spurs (osteophytes) to decompress neural elements.
-
Service type: Surgical procedure — anterior lumbar discectomy with decompression and osteophytectomy
-
Typical site of service: Inpatient or outpatient hospital operating room; may also occur in an ambulatory surgery center depending on clinical complexity and payer policies
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient presents with progressive low back pain radiating to the anterior thigh and lower leg with associated neurogenic claudication and objective motor weakness. Conservative management including physical therapy, oral analgesics, and epidural steroid injections has failed over 12 weeks. MRI of the lumbar spine demonstrates a large central and foraminal disc herniation at L4-L5 with compression of the thecal sac and L5 nerve roots and associated osteophyte formation. The spine surgeon schedules an anterior lumbar discectomy with decompression of the spinal cord and/or nerve roots, including osteophytectomy at a single lumbar interspace.
Typical clinical workflow:
-
Preoperative evaluation and clearance by primary care and anesthesia.
-
Preoperative imaging review (MRI, CT if needed) and informed consent documenting neurologic deficits and indication for anterior approach.
-
Operating room: patient positioned supine or in lateral decubitus per surgeon preference; anterior retroperitoneal or transperitoneal exposure to the lumbar spine; discectomy performed at a single interspace with removal of herniated disc material and osteophytectomy; decompression of neural elements confirmed.
-
Closure and transfer to PACU; postoperative inpatient monitoring for neurologic status, hemodynamics, and wound/visceral complications.
-
Postoperative follow-up includes wound check, activity restrictions, pain management, and progressive rehabilitation as indicated.
