Summary & Overview

CPT 74175: Abdominal CT Angiography with Contrast

CPT code 74175 denotes computed tomography angiography (CTA) of the abdomen performed with intravenous contrast, including angiographic reconstruction and interpretation; non-contrast images, if obtained, are part of the procedure. This imaging code is central to evaluation of abdominal vascular pathology — including suspected aneurysm, dissection, stenosis, or thrombosis — and is widely used across acute care, outpatient imaging, and preoperative planning. Nationally, CTA of the abdomen is a high-volume diagnostic service with implications for access to advanced imaging, utilization management, and coverage policy.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and common sites of service, a summary of payer coverage considerations and coding context, and benchmarking insights where available. The publication highlights common billing modifiers and service-line considerations, summarizes clinical contexts in which 74175 is typically reported, and notes where input data were not provided. This resource is intended for coding professionals, compliance staff, and policy analysts seeking a focused reference on national use, coding definition, and payer landscape for CPT code 74175.

Billing Code Overview

CPT code 74175 describes a computed tomography angiography (CTA) of the abdomen performed with contrast material. The procedure includes acquisition of contrast-enhanced images, reconstruction and post-processing of angiographic datasets, and interpretation. Non-contrast images, if obtained, are also included in the procedure.

Service type: Diagnostic imaging — CT angiography with contrast and image reconstruction

Typical site of service: Outpatient imaging centers, hospital radiology departments, and emergency department imaging suites

Data not available in the input: Associated taxonomies, ICD-10 diagnoses, and related codes.

Clinical & Coding Specifications

Clinical Context

A 68-year-old male with a history of peripheral arterial disease and poorly controlled hypertension presents with progressive abdominal and flank pain and an acute decline in renal function. The clinician suspects an abdominal aortic aneurysm with possible involvement of the renal or mesenteric vessels. The patient is referred to radiology for a contrast-enhanced computed tomography angiography of the abdomen to evaluate aortic caliber, aneurysm morphology, branch vessel patency, and potential endoleak if prior repair exists. In the radiology workflow the patient is screened for contrast allergy and renal function, intravenous access is established, and contrast is administered per protocol. The CT technologist acquires arterial-phase CTA images of the abdomen; post-processing performs multiplanar reconstructions and 3D angiographic reformats. The radiologist interprets the images, documents vessel measurements, describes stenosis or occlusion, and provides findings that inform vascular surgery or interventional planning. Non-contrast images (if obtained for calcification or baseline) are included in the overall study interpretation.

`I71.4`	Abdominal aortic aneurysm, without rupture	CTA assesses aneurysm morphology and branch involvement for surveillance or elective repair planning.
`I77.1`	Stricture of artery	CTA identifies arterial stenosis location and severity in mesenteric or renal arteries.
`K55.0`	Acute vascular insufficiency of intestine	CTA can detect mesenteric ischemia and vascular occlusion causing intestinal ischemia.
