CPT 0807T: CT and Cinefluorography Fusion for Lung Ventilation Quantification

CPT code 0807T covers an advanced, software-driven imaging service that combines cinefluorograph sequences with prior CT scans to quantify pulmonary tissue ventilation, provide interpretation, and produce a clinical report. The code reflects growing adoption of image-fusion analytics to support diagnosis and management of regional lung function, with implications for preprocedural planning, monitoring of disease progression, and assessing response to therapies. Nationally, the code matters as payers, imaging centers, and clinical teams negotiate coverage, coding workflows, and integration of quantitative imaging into care pathways.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of payer coverage patterns, customary sites of service and clinical contexts for use, typical service components included in the code, and benchmarks where available. The publication also summarizes coding considerations, common procedural modifiers, and operational impacts for imaging and pulmonary service lines.

This report is intended to inform stakeholders about the clinical purpose of 0807T, how it is billed and documented, and the broader policy and reimbursement context affecting adoption across outpatient imaging and hospital settings.

Billing Code Overview

CPT code 0807T describes a software-assisted analysis of pulmonary ventilation that fuses separately captured cinefluorograph images with previously acquired CT images. The service covers data preparation and transmission, quantitative measurement of pulmonary tissue ventilation, clinician review and interpretation, and generation of a diagnostic report.

Service type: Advanced image-processing diagnostic service combining fluoroscopy and CT-based ventilation quantification
Typical site of service: Hospital outpatient imaging centers, ambulatory imaging centers, and specialized radiology or pulmonary function laboratories

Clinical Context

A 68-year-old patient with chronic obstructive pulmonary disease and progressive dyspnea is referred for functional assessment of regional lung ventilation to guide treatment planning. The patient previously underwent a diagnostic chest CT that captured volumetric lung anatomy. At the fluoroscopy suite, the provider performs cinefluorography focused on targeted lung regions while the patient performs controlled breathing maneuvers. The provider uses specialized software that combines the newly captured cinefluorograph sequences with the previously acquired CT dataset to quantify regional pulmonary tissue ventilation. Clinical workflow steps include: patient check-in and consent; retrieval and quality check of prior CT images; acquisition of cinefluorograph images with dose-minimization protocols; secure transmission of cine and CT data to the analytic software; automated and manual data preparation and registration; software-derived ventilation quantification; physician review, interpretation, and documentation; and generation of a finalized report communicated to the referring pulmonologist or thoracic surgeon for treatment planning (for example, lung volume reduction, bronchoscopic intervention, or radiation planning). Typical site of service is an outpatient hospital radiology or interventional fluoroscopy suite, or an ambulatory imaging center with fluoroscopic capability. Typical patient scenario involves pre-procedural functional mapping, evaluation of heterogeneous emphysema, or assessment of regional ventilation before targeted therapies.
