Computer-Aided Detection (CAD) System for Use with Chest Radiographs


The use of computer-aided detection (CAD) systems with chest radiographs is considered experimental/investigational and, therefore, not covered because the safety and/or effectiveness of this service cannot be established by review of the available published literature.


There is no Medicare coverage criteria addressing this service; therefore, the Company policy is applicable.


Subject to the terms and conditions of the applicable Evidence of Coverage, the use of computer-aided detection (CAD) systems with chest radiographs is not eligible for payment under the medical benefits of the Company’s Medicare Advantage products because the service is considered experimental/investigational and, therefore, not covered.

Services that are experimental/investigational are excluded for the Company’s Medicare Advantage products. Therefore, they are not eligible for reimbursement consideration.


The RapidScreen™ RS-2000 (Deus Technologies, Rockville, MD) received premarket approval (PMA) on July 12, 2001, from the FDA for use as a computer-aided detection (CAD) system.


A computer-aided detection (CAD) system is used as an adjunctive tool in assessing chest radiographs. The basic function of CAD is to provide radiologists with a computer algorithm that assists with interpreting radiological images. CAD is thought to improve the accuracy and consistency of radiological diagnosis by reducing the time it takes to interpret images.

The RapidScreen™ RS-2000 (Deus Technologies, Rockville, MD) is a CAD system that identifies and marks regions of interest on digitized frontal chest radiographs. It is believed to identify features associated with solitary pulmonary nodules from 9 mm to 30 mm in size, which could represent early-stage lung cancer. The device is intended for use as an aid only after a physician has performed a preliminary interpretation of the radiograph.

The published literature regarding CAD for chest X-rays consists primarily of the technical capabilities of CAD systems. High-quality, randomized trials examining the effect of CAD systems for chest X-rays on lung cancer morbidity and mortality are necessary to determine the true impact of this technology on health outcomes. There is a paucity of literature that supports the efficacy of this modality at this time.
