CPT code 22532 defines thoracic spinal arthrodesis performed through a lateral extracavitary approach to fuse two vertebrae and alleviate pain or instability from disorders such as herniated disks, spinal stenosis, or traumatic injury. The code captures a complex operative technique that provides enhanced visualization of the thoracic spine and enables removal of disk material and preparation of bone for fusion. Nationally, procedures represented by CPT code 22532 are clinically significant given the resource intensity, surgical expertise, and potential impact on patient outcomes and post-acute care needs.

Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks and coverage patterns relevant to these payers, plus discussion of clinical context and service-line implications. The publication outlines utilization and payment benchmarks, coding and billing considerations, and policy updates that affect hospital and surgical center reimbursement for thoracic fusion procedures. Clinical indications, typical sites of service, and the operative approach are summarized to orient billing, finance, and clinical teams to the factors that drive coding, authorization, and claims adjudication for CPT code 22532.
