CPT code 71101 denotes a three-view unilateral radiologic study of the ribs that includes a posteroanterior chest view. The code captures imaging performed to identify rib fractures, bony lesions, or other rib-related conditions and is commonly used across emergency departments, outpatient imaging centers, and hospital radiology departments. Nationally, accurate coding for rib radiography affects clinical documentation, claims processing, and utilization tracking for musculoskeletal and trauma care.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for performing this study, typical sites of service, and common claim considerations tied to radiology service lines. The publication summarizes benchmarks and coding practice patterns where available, highlights documentation elements that support code selection, and outlines areas where payers commonly require clarity (for example, laterality and inclusion of chest PA view). It also points to policy and billing nuances relevant to emergency and inpatient settings.

This summary provides clinicians, coders, and billing professionals with a practical reference to understand when CPT code 71101 is used and what aspects of documentation and service setting influence its application.
