Summary & Overview
CPT 22856: Cervical Artificial Disc Replacement, Single Level
CPT code 22856 represents single-level cervical total disc arthroplasty, a surgical procedure that removes a diseased intervertebral disc, relieves neural compression by removing osteophytes, and implants an artificial disc to preserve motion. This code is clinically important as an alternative to fusion for select patients with degenerative disc disease and related cervical disc pathologies, and it has implications for device coverage, utilization patterns, and postoperative outcomes across the U.S.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and typical settings, an explanation of how the code is used in billing, and what to expect from payer coverage policies. The publication also summarizes benchmarking metrics where available, recent policy trends affecting coverage and prior authorization, and notes on clinical context such as target diagnoses and procedural goals.
This material is intended to inform clinicians, coding professionals, and policy analysts about the role of CPT code 22856 in surgical spine practice and payer interactions at a national level. Data not available in the input is indicated where applicable.
Billing Code Overview
CPT code 22856 describes total disc arthroplasty of the cervical spine at a single intervertebral level. The procedure involves removal of the intervertebral disc, excision of osteophytes (bone spurs) at the adjacent vertebral endplates to decompress neural elements, and placement of an artificial cervical disc to restore disc height and motion.

Clinical & Coding Specifications
Clinical Context
A 48-year-old patient with a multi-year history of progressive neck pain radiating into the right upper extremity, refractory to conservative care (physical therapy, oral analgesics, and epidural steroid injection), presents with objective neurologic findings of right C6 radiculopathy and MRI-confirmed single-level cervical disc degeneration with posterior osteophyte formation causing neural foraminal and central canal compromise. After multidisciplinary review and informed consent, the patient undergoes an anterior cervical discectomy with insertion of a single-level cervical artificial disc (CPT 22856) to remove the degenerated intervertebral disc and osteophytes and restore disc height and motion. Typical clinical workflow: preoperative evaluation and clearance, intraoperative neuromonitoring and fluoroscopic localization, anterior cervical approach, discectomy and osteophyte removal, implantation of the cervical disc prosthesis, wound closure, immediate postoperative recovery in the PACU, and planned short inpatient observation or same-day discharge depending on comorbidities and institutional protocol. Typical site of service is an ambulatory surgery center or hospital operating room staffed by an orthopedic spine or neurosurgery team. Typical service type is major surgical orthopedic/spinal implant procedure requiring general anesthesia.
