Summary & Overview
CPT 9002F: Aortic Aneurysm Documented 5.0–5.4 cm on CT
CPT code 9002F represents provider documentation of an aortic aneurysm with a diameter of 5.0 to 5.4 cm identified on computed tomography. Accurate size documentation for aortic aneurysms is clinically important because diameter thresholds inform surveillance intervals and decisions about elective repair; standardized coding supports consistent reporting for quality measurement and payer adjudication. Nationally, this type of documented finding influences imaging follow-up, specialty referral patterns, and population-level monitoring of aortic disease.
This analysis covers major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks for utilization and coverage trends, context on clinical thresholds tied to the code, and notes on documentation practices that affect claims processing. The report also summarizes how the code fits into clinical workflows for diagnostic imaging and vascular surgery referral pathways.
What readers will learn: the clinical meaning of the code and its implications for care coordination; typical sites of service where the code is recorded; payer coverage considerations and common claims issues; and where documentation quality affects reporting and payment. Data not available in the input is clearly marked in the relevant sections.
Billing Code Overview
CPT code 9002F documents an aortic aneurysm measuring 5.0 to 5.4 cm in diameter as identified on a computed tomographic (CT) imaging study. This code indicates that the provider recorded the presence and size of a weakened, bulging section of the aorta using CT imaging.
-
Service type: Diagnostic imaging interpretation and clinical documentation of aortic aneurysm size
-
Typical site of service: Hospital radiology department or outpatient imaging center
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a history of hypertension and tobacco use presents for surveillance imaging after an incidental abdominal aortic aneurysm (AAA) was identified on prior imaging. The patient undergoes a contrast-enhanced computed tomographic (CT) angiography of the abdomen and pelvis to characterize aneurysm size, extent, and features. The radiologist documents an aortic aneurysm with a maximal transverse diameter of 5.0 to 5.4 cm. Clinical workflow: outpatient referral from primary care or vascular surgery → pre-procedure assessment and IV contrast screening → CT angiography performed in the radiology suite → radiologist measures aneurysm dimensions, assesses for mural thrombus, dissection, or rupture signs, and issues an official read; results are communicated to the referring vascular surgeon for management planning (continued surveillance vs. elective repair). Typical site of service: hospital outpatient radiology department or freestanding imaging center.
