CPT code 72040 denotes a 2– or 3–view radiographic examination of the cervical spine. This common diagnostic radiology service is used to assess cervical vertebrae for fractures, malalignment, and degenerative changes, making it a frequent component of emergency, outpatient, and inpatient care pathways nationwide. The code matters nationally because cervical spine radiography remains a first-line imaging study in many clinical scenarios and influences downstream imaging and clinical decision-making.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coding definitions, clinical context for when a 2– or 3–view cervical spine series is typically obtained, and operational considerations for sites of service that commonly perform the study. The publication will also summarize common modifiers and billing practices used with radiography codes, benchmark payment and utilization patterns where available, and recent policy developments that affect how payers adjudicate cervical spine X-ray claims.
