Summary & Overview
CPT 9003F: CT-Documented Aortic Aneurysm, 5.5–5.9 cm
CPT code 9003F denotes documentation that a CT imaging study identified an aortic aneurysm measuring 5.5 to 5.9 cm in diameter. This code captures a specific imaging-derived clinical finding that can affect clinical decision-making, surveillance intervals, and eligibility for surgical or endovascular intervention. Nationally, clear clinical documentation of aneurysm size is important for care coordination between imagers, vascular surgeons, and payers.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on the clinical meaning of aortic aneurysm sizing on CT, the typical service setting where the finding is recorded, and the implications for downstream care pathways. The publication also outlines benchmarking and coding usage perspectives where available, discusses policy-related considerations tied to imaging documentation, and highlights areas where payers commonly focus review efforts.
This summary is intended for healthcare administrators, coding professionals, and clinicians seeking a concise reference on the purpose of CPT code 9003F, its clinical context, and where it fits into imaging-driven documentation and subsequent care processes. Data not available in the input has been noted and omitted from detailed payer-specific benchmarks.
Billing Code Overview
CPT code 9003F documents an aortic aneurysm identified on computed tomographic (CT) imaging with a measured diameter of 5.5 to 5.9 cm. The notation describes a weakened, bulging section of the aorta at that specific size range and is used to record the imaging-based finding in the medical record.
Service Type: Imaging-derived diagnostic documentation of an aortic aneurysm
Typical Site of Service: Hospital radiology department or outpatient imaging center, where CT imaging studies of the chest or abdomen are performed.
Clinical & Coding Specifications
Clinical Context
A 72-year-old male with a history of hypertension and smoking undergoes contrast-enhanced computed tomography (CT) of the chest and abdomen for evaluation of suspected aortic disease after an enlarged aortic silhouette was noted on chest radiograph and the patient reports new-onset back pain. The CT demonstrates an infrarenal aortic aneurysm measuring 5.7 cm in maximal diameter. The vascular surgery team documents the finding in the radiology report and the treating provider documents the diagnosis and size in the medical record, noting the diameter within the range of 5.5 to 5.9 cm. The clinical workflow includes imaging acquisition, radiologist interpretation, documentation of aneurysm size and location, vascular surgery consultation, and discussion of management options (surveillance vs. elective repair). Billing for the encounter includes reporting of the documented diagnosis code for aortic aneurysm and the quality-reporting CPT/HCPCS measure code 9003F to indicate that the provider documented an aortic aneurysm with diameter 5.5–5.9 cm on CT imaging.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician interpretation portion of a diagnostic imaging service. |
TC | Technical component | Use when billing only the facility/technical portion of a diagnostic imaging service. |
59 | Distinct procedural service | Use when a separate, distinct service is performed on the same day and is not normally bundled. |
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of a procedure | Use when an E/M visit is performed and documented separately from the imaging interpretation or procedure. |
78 | Return to operating room for related procedure during postoperative period | Use when a patient returns to the OR for a related procedure during the global period after aneurysm repair. |
79 | Unrelated procedure or service by the same physician during the postoperative period | Use when an unrelated procedure is performed during the postoperative global period. |
52 | Reduced services | Use when a service is partially reduced or not completed as documented. |
QW | CLIA-waived test | Not typically applicable to imaging; included for completeness when waived tests are performed during the same encounter. |
GC | Service performed in part by a resident under direction of a teaching physician | Use when a resident documents or participates and attestation meets teaching physician rules. |
RT | Right side | Use when laterality is required and the right side is specifically reported (rare for aortic imaging). |

Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
I71.4 | Abdominal aortic aneurysm, without rupture | Most commonly associated diagnosis when a CT documents an infrarenal aortic aneurysm measuring 5.5–5.9 cm; guides management decisions. |
I71.2 | Thoracic aortic aneurysm, without rupture | Relevant if the aneurysm is located in the thoracic aorta and documented on chest CT. |
I71.3 | Thoracoabdominal aortic aneurysm, without rupture | Used when the aneurysm spans thoracic and abdominal segments documented on imaging. |
I71.9 | Aortic aneurysm, unspecified, without rupture | Used when documentation does not specify location; less ideal but clinically accepted when specifics are lacking. |
I71.8 | Other aortic aneurysm and dissection | Used when complex aortic pathology or combined aneurysm and dissection findings are present on imaging. |
