Summary & Overview
CPT 75733: Bilateral Selective Adrenal Artery Angiography, Radiological Supervision and Interpretation
CPT code 75733 covers the radiological supervision and interpretation associated with bilateral selective catheter placement in the adrenal arteries during an angiographic study. This code captures the physician or qualified professional component for targeted adrenal vessel imaging that informs diagnosis and interventions for adrenal vascular or endocrine conditions. Nationally, accurate coding of angiographic interpretation affects clinical documentation, billing consistency, and appropriate use of advanced imaging resources.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context, typical sites of service, and the role of the procedure in care pathways. The publication includes benchmarking and payment context where available, coding guidance on service attribution, and summary notes on common modifiers and reporting scenarios. It also outlines clinical situations that commonly prompt bilateral adrenal angiography and operational considerations for imaging departments.
This overview is intended for billing specialists, radiology clinicians, and revenue cycle staff seeking a national-level summary of CPT code 75733, its clinical purpose, and the administrative context relevant to its use.
Billing Code Overview
CPT code 75733 describes the radiological supervision and interpretation of a bilateral selective catheter placement in the adrenal arteries as part of an angiographic study. Angiography uses a radiopaque contrast agent to visualize blood vessels under X‑ray to help diagnose and guide treatment of vascular and endocrine conditions affecting the adrenal circulation.
Service type: Radiological supervision and interpretation for bilateral selective adrenal arterial catheterization
Typical site of service: Hospital radiology suite, interventional radiology lab, or outpatient imaging center
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with refractory hypertension and episodic headaches despite multi‑drug therapy. Noninvasive testing (plasma metanephrines and CT imaging) suggests an adrenal lesion suspicious for a functioning pheochromocytoma. Interventional radiology is consulted for diagnostic angiography to evaluate adrenal arterial anatomy and to localize tumor vascular supply prior to possible embolization or surgical planning. The patient is admitted to the hospital same‑day for the procedure.
The clinical workflow includes pre‑procedure review of labs and imaging, informed consent, arterial access (commonly common femoral artery), selective catheterization of the right and left adrenal arteries under fluoroscopic guidance, injection of radiopaque contrast for arteriography, radiological supervision and interpretation by the attending interventional radiologist, and post‑procedure monitoring for access site complications and contrast reactions. The service represented by 75733 covers the radiological supervision and interpretation of the bilateral selective placement of a catheter in the adrenal artery.
