Headline: New CPT code 0879T flags specialized workflow for chest CT imaging sent for interstitial lung disease classification

Lead: CPT code 0879T captures the clinical and technical workflow in which a provider prepares and transmits chest computed tomography imaging to a specialized program that performs separate classification of interstitial lung disease. The code recognizes a distinct, billable step in the imaging-to-analytics pathway as imaging platforms and AI-driven classifiers are more frequently used in ILD evaluation.

CPT code 0879T represents a procedural descriptor for image preparation and transmission rather than image acquisition or interpretation alone. Nationally, the code matters because it delineates a discrete service that may be billed when chest CT data is routed to third-party or specialized analytic programs for ILD classification, affecting billing workflows across radiology practices and imaging centers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how the code is defined, the clinical context for use in interstitial lung disease evaluation, and the service settings where the code applies. The publication also provides benchmarks and policy context relevant to reimbursement coding, common modifiers encountered, and implications for documentation and claims processing.

This summary is intended for national audiences seeking concise guidance on the clinical role and billing context of CPT code 0879T.
