Summary & Overview
CPT 75840: Adrenal Vein Selective Venography Supervision & Interpretation
CPT code 75840 represents the physician supervision and interpretation component for a selective adrenal venography performed on one side. This service is used when targeted venous imaging of the adrenal gland is required to evaluate vascular anatomy or localize hormone-secreting lesions. Nationally, the code is relevant for radiology and endocrinology workflows where specialized venous sampling and imaging inform diagnosis and treatment plans.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines coverage and reimbursement benchmarks, common billing practices, and the clinical context in which selective adrenal venography is performed. Readers will find concise benchmarks for utilization and payment patterns, discussion of coding and documentation essentials for supervision and interpretation services, and clinical considerations tied to imaging location and procedural role. The content also highlights common modifiers and payer-specific billing nuances where available.
Data not available in the input for specific payer rates, related taxonomies, ICD-10 diagnoses, and associated service-line mappings. The article focuses on national-level implications for billing, clinical workflow, and administrative handling of CPT code 75840.
Billing Code Overview
CPT code 75840 describes the supervision and interpretation of a selective venography of the adrenal vein on one side of the body. The service involves real-time oversight of contrast injection and fluoroscopic imaging, followed by interpretation of the venographic images to evaluate adrenal venous anatomy and drainage.
-
Service type: Diagnostic vascular imaging supervision and interpretation
-
Typical site of service: Hospital radiology department or outpatient imaging center (interventional radiology suite)
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult referred for adrenal vein venography to evaluate suspected primary hyperaldosteronism or an adrenal mass with possible hormonal activity. The patient presentation often includes hypertension resistant to medical therapy, hypokalemia, or biochemical evidence of aldosterone excess. The interventional radiology team performs the procedure in an angiography suite or interventional radiology operating room under moderate sedation or general anesthesia depending on comorbidities and institutional practice. Vascular access is obtained (commonly via a femoral or internal jugular approach), selective catheterization of the unilateral adrenal vein is performed, contrast is injected, and fluoroscopic imaging is acquired. The supervising physician performs real‑time interpretation of venographic images, documents findings (venous anatomy, venous drainage patterns, presence of thrombus or filling defects, and contrast reflux), and provides a diagnostic impression and recommendations for further management. The typical site of service is an outpatient ambulatory surgery center or hospital-based interventional radiology suite. Post‑procedure monitoring includes observation for access site complications, vital sign stability, and confirmation of no allergic reaction to contrast before discharge or admission if indicated.
