Summary & Overview
CPT 22612: Lumbar Spinal Fusion (Arthrodesis)
Headline: CPT code 22612: Lumbar spinal fusion (arthrodesis) for stabilization and pain relief
Lead: CPT code 22612 identifies lumbar spine arthrodesis procedures in which a surgeon applies bone graft material to fuse two vertebrae, stabilizing the lower back and addressing pain from conditions such as herniated discs, spinal stenosis, and injury. This code captures a high-cost, high-impact surgical intervention with implications for utilization management and postoperative care pathways across payers.
Why it matters: Lumbar fusion procedures are common drivers of surgical spending and care variation nationwide. CPT code 22612 is used to bill for posterior and posterolateral approaches to lumbar fusion and is relevant to inpatient stays, same-day surgeries in ambulatory surgical centers, and bundled payment arrangements.
Payers covered: Analysis and benchmarking typically consider major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication provides clinical context for CPT code 22612, explains typical sites of service and service type, and summarizes payer coverage patterns and common billing modifiers where available. It highlights points of policy interest for national payers, utilization drivers, and areas of clinical documentation that commonly affect claim adjudication.
Data limitations: Data not available in the input for associated taxonomies, ICD-10 diagnoses, related codes, and detailed payer-specific reimbursement rates.
Billing Code Overview
CPT code 22612 describes arthrodesis (spinal fusion) of the lumbar spine, a surgical procedure that permanently joins two vertebrae to stabilize the lower back and reduce pain. The provider applies bone graft material to promote fusion at the back of the vertebrae, at the back and side, or at the side and across to achieve a solid osseous union.
Service type: Surgical procedure — lumbar spinal fusion (arthrodesis).
Typical site of service: Hospital operating room or ambulatory surgical center (inpatient or outpatient surgical setting depending on clinical factors).
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with chronic low back pain and neurogenic claudication refractory to conservative therapy (physical therapy, lumbar epidural steroid injections, and analgesics) presents with progressive radiographic lumbar degenerative spondylolisthesis and multilevel lumbar spinal stenosis. Imaging with MRI and standing radiographs demonstrates instability at L4–L5 with foraminal compromise and degeneration of the facet joints. The spine surgeon recommends posterior lumbar arthrodesis to stabilize the segment and decompress neural elements. The typical clinical workflow includes preoperative evaluation and medical optimization, informed consent discussing risks and benefits, preoperative imaging review, intraoperative general anesthesia, posterior approach with decompression (laminectomy/foraminotomy as indicated), placement of bone graft (autograft or allograft) and instrumentation as necessary, intraoperative neuromonitoring when used, postoperative recovery in the hospital or ambulatory surgery center depending on complexity and patient comorbidities, and routine postoperative follow-up with wound checks and radiographic assessment for fusion.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work, time, and effort for the fusion are substantially greater than typical due to extensive scarring, prior surgery, or unexpected complexity. |
| 23 | Unusual anesthesia | Use when the procedure is performed under general anesthesia but circumstances prevent the use of regional or local anesthesia when normally expected.
