Summary & Overview
CPT 75833: Supervision & Interpretation of Renal Selective Venography
CPT code 75833 denotes the physician supervision and interpretation of selective venography of both kidneys, an invasive imaging study using contrast to visualize renal veins and detect thrombus or venous obstruction. This code matters nationally because selective renal venography is a definitive diagnostic tool when noninvasive imaging is inconclusive, and its oversight and interpretation have implications for procedure utilization, facility resource use, and specialty billing patterns.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, payer coverage considerations, and benchmarking topics relevant to utilization and billing for invasive venography. The publication summarizes how this service fits into vascular and interventional radiology workflows and the typical sites of service where the procedure is performed.
The report provides benchmarks and coverage themes, flags areas where policy updates or prior authorization practices can affect access, and outlines the clinical indications that commonly drive use. Data not available in the input is noted where applicable. The focus is national in scope and intended for payers, billing professionals, and clinical administrators seeking a clear reference on CPT code 75833.
Billing Code Overview
CPT code 75833 describes the provider supervision and interpretation of selective venography of both kidneys. This is an invasive diagnostic imaging procedure in which contrast dye is injected into the renal venous system and X-ray images are taken to identify the location and degree of venous clot or obstruction.
-
Service type: Invasive diagnostic venography with provider supervision and interpretation
-
Typical site of service: Hospital radiology department or interventional radiology suite; may also occur in specialized outpatient imaging centers equipped for invasive vascular procedures

Clinical & Coding Specifications
Clinical Context
A typical patient is a 56-year-old hospitalized individual with acute flank pain, hematuria, or unexplained decline in renal function and clinical suspicion for renal vein thrombosis after inconclusive noninvasive imaging (ultrasound, CT venography). The patient is referred to interventional radiology for diagnostic selective renal venography. Pre-procedure workflow includes review of indications and anticoagulation status, informed consent, assessment of renal function and contrast allergy, and placement into an angiography suite. Under conscious sedation or monitored anesthesia, vascular access (commonly femoral or jugular) is obtained, catheterization of bilateral renal veins is performed, iodinated contrast is injected selectively, and fluoroscopic imaging is obtained to identify thrombus location and extent. The supervising physician documents supervision and interpretation of the venograms, including hemodynamic measurements if obtained, and provides a formal report describing clot presence, degree of occlusion, collateral flow, and any recommended next steps. Post-procedure includes monitoring for access-site complications, contrast nephropathy, and documentation of findings and plan for anticoagulation or endovascular therapy if indicated.
