Summary & Overview
CPT 22548: Cervical Spine Arthrodesis (Anterior/Transoral)
CPT code 22548 represents anterior or transoral cervical arthrodesis (spinal fusion) performed to permanently join two vertebrae in the neck. The procedure treats persistent pain and neurologic compromise from herniated disks, spinal stenosis, or traumatic injury by stabilizing the cervical spine. Nationally, cervical fusion procedures are significant contributors to surgical spine care volume and to resource use in both inpatient and ambulatory surgical settings.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and service setting, common payer coverage patterns, relevant billing and coding context, and benchmarking information where available. The publication highlights allowable sites of service, typical surgical approach options (anterior neck and transoral), and how the code fits within broader spinal surgery service lines.
This summary is intended for clinicians, coding and billing professionals, and policy analysts seeking a national perspective on CPT code 22548, including clinical context, payer coverage considerations, and the types of benchmarks and policy updates that affect utilization and reimbursement. Data not available in the input will be identified in relevant sections of the full publication.
Billing Code Overview
CPT code 22548 describes arthrodesis (spinal fusion) of the cervical spine, a surgical procedure that permanently joins two vertebrae in the neck. The provider accesses the cervical vertebrae through an incision in the mouth (transoral approach) or in the anterior neck (anterior cervical approach) and may include excision of the first cervical vertebra when clinically indicated. The procedure is performed to alleviate persistent neck pain and neurologic symptoms caused by conditions such as herniated or bulging intervertebral disks, spinal canal narrowing (spinal stenosis), or traumatic spinal injuries.
Service type: Surgical — cervical spinal fusion (anterior/transoral arthrodesis)
Typical site of service: Hospital operating room or ambulatory surgical center (inpatient or outpatient surgical setting depending on clinical factors and payer policies)
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with progressive neck pain, cervical radiculopathy and weakness in the upper extremity after conservative care including physical therapy and epidural steroid injections failed over several months. Imaging (MRI and CT) demonstrates multilevel cervical spondylosis with foraminal stenosis and a symptomatic degenerative disc at C4–C5 with foraminal nerve root compression and instability. The spine surgeon recommends an anterior cervical arthrodesis (spinal fusion) to decompress the neural elements and stabilize the cervical segment.
Preoperative workflow includes history and physical, optimization of medical comorbidities, informed consent discussing risks (infection, dysphagia, neurovascular injury), and anesthesia evaluation. The procedure is performed in an operating room with general anesthesia. The surgeon makes an anterior approach through an incision in the neck (or transoral approach in select high cervical cases), performs discectomy and decompression, prepares endplates, places an interbody spacer or bone graft, and secures fixation with anterior plating or screws to achieve arthrodesis. Intraoperative neuromonitoring and fluoroscopy are commonly used. Postoperative care includes short inpatient observation or overnight stay, pain control, wound checks, cervical immobilization as indicated, and outpatient follow-up with imaging to assess fusion progress.
