Summary & Overview
CPT 22100: Excision of Posterior Cervical Vertebral Bone
CPT code 22100 covers the surgical excision of a portion of the posterior element of a single cervical vertebra to remove a bony lesion contained within that bone. This targeted spinal procedure is clinically important for treating benign or localized destructive processes of a cervical vertebra and can prevent neurological compromise or progression of disease. Nationally, it is relevant to hospital and ambulatory surgery billing, surgical specialty workflows, and Medicare payment policies.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, common billing considerations, and where this service typically occurs. The publication summarizes benchmark information and payer coverage patterns where available, notes common modifiers used in practice, and highlights policy or coding guidance that affects claims processing.
This summary equips clinicians, coding professionals, and policy analysts with an overview of CPT code 22100, clarifies the procedure’s clinical intent and site-of-service expectations, and outlines the types of documentation and coding points that commonly influence reimbursement and utilization review. Data not available in the input is identified where applicable.
Billing Code Overview
CPT code 22100 describes the surgical excision of part of the posterior element of a cervical vertebra to remove a bony lesion confined to a single cervical vertebral bone. This procedure involves removing bone from the back portion of one cervical vertebra to access and excise a localized diseased or abnormal bony area.
-
Service type: Surgical excision of posterior cervical vertebral bone (open surgical procedure)
-
Typical site of service: Hospital operating room or ambulatory surgical center, performed by a spine surgeon or neurosurgeon
Clinical & Coding Specifications
Clinical Context
A typical patient is a middle-aged or older adult presenting with localized neck pain, focal cervical spine tenderness, or neurologic symptoms (radiculopathy or myelopathy) attributable to a solitary bony lesion of a single cervical vertebra. Imaging (cervical spine radiographs, CT, and MRI) demonstrates an isolated lytic or sclerotic lesion confined to the posterior elements of one cervical vertebra (lamina or spinous process) suspicious for a benign tumor, bone cyst, metastatic deposit, or osteomyelitic focus. The surgical team—commonly an orthopedic spine surgeon or neurosurgeon—performs a posterior cervical approach under general anesthesia in an operating room. Intraoperative neuromonitoring and fluoroscopy or CT navigation may be used. The provider excises the diseased portion of the posterior vertebral element (laminectomy or partial excision of the lamina/spinous process) to remove the lesion while preserving spinal stability; bone specimens are sent for pathology and microbiology as indicated. Postoperative care includes pain control, wound management, possible cervical immobilization, and follow-up imaging. Typical site of service is an inpatient or outpatient hospital operating room depending on extent of surgery and patient comorbidity.
