Computed tomographic angiography (CTA) reimbursement issues
The following article is published by the American Hospital Association’s Central Office on HCPCS in collaboration with the American College of Radiology. Computed tomographic angiography (CTA), a less-invasive technique for imaging vessels (both arteries and veins), has gained widespread usage in clinical practice. Prior to the introduction of this new technique, vascular evaluation was performed primarily by invasive catheter angiography. CTA offers important advantages over conventional angiography, which only depicts the vascular lumen. With CTA, additional information is provided, including vessel wall thickness, relationship to adjacent structures, enhanced depiction of the venous anatomy, and parenchymal information about the...

Article Overview
This article reviews the scope of computed tomographic angiography (CTA) as it relates to hospital coding, chargemaster setup, and outpatient reimbursement. It explains the general categories of CTA services, how CTA is distinguished from related CT and angiography studies, and why payment treatment in the hospital setting became an issue for providers and administrators. The article is aimed at radiology coders, hospital revenue cycle staff, and imaging administrators who need to understand the broader coding and payment context for CTA.
Why This Topic Matters
CTA is a high-volume imaging service with distinct technical and post-processing components, so coding and charge capture can affect reimbursement accuracy. Understanding the article helps hospital and radiology teams recognize the broader billing and payment issues tied to CTA reporting and related imaging services.
Article Sections
-
Description of procedure
Introduces the general elements of CTA image acquisition and post-processing. It also distinguishes CTA from more general CT imaging at a high level.
-
Coding
Summarizes the CTA code family and discusses broad coding relationships to related imaging components and supplies. It also addresses how one CTA category is distinguished from another broad vascular study type.
-
Computed tomography (CT) in conjunction with CTA
Discusses when separate CT and CTA studies may both be performed in the same encounter. The section focuses on the relationship between distinct data sets and separate reporting at a general level.
-
Distinctions between computed tomographic angiography (CTA) and magnetic resonance angiography (MRA)
Compares CTA with MRA in broad operational and reporting terms. It also addresses the relationship of post-processing and separately performed studies across modalities.
-
Distinction between CT and CTA costs, charges and reimbursements
Reviews hospital payment and charge-reporting issues associated with CTA. It discusses the broader reimbursement context, including APC treatment and CMS-related payment concerns.
