    National Reimbursement Benchmarks

    Commercial national rates for CPT 01933 center around BUCA’s average commercial benchmark of $75.00, while individual payers vary: Aetna and UnitedHealth Group cluster below BUCA’s mean with medians near $48 and $63.50 respectively, Blue Cross Blue Shield sits slightly above with a median near $59, and Cigna is notably higher with a median of $97.90. The highest single reported ceiling is Blue Cross Blue Shield at $215.40 and the lowest floor is BCBS at $3.40, indicating endpoints outside the interquartile comparisons.

    Dispersion measured by the interquartile range (P75−P25) reveals Cigna as the widest at $93.00 (P75 $133.00 minus P25 $77.70), followed by UnitedHealth Group at $29.20, Blue Cross Blue Shield at $43.99, Aetna at $49.30, and BUCA at $39.00. Cigna’s substantially larger IQR highlights greater variability in commercial contracted rates relative to other major carriers.

    Clinical & Coding Specifications

    Clinical Context

    A 58-year-old patient with a history of progressive headaches and radiographically confirmed dural venous sinus thrombosis is scheduled for an endovascular thrombolysis and mechanical thrombectomy involving the intracranial venous system. The patient arrives at the interventional radiology suite after pre-procedure evaluation in the hospital. An anesthesiology team performs a focused pre-anesthesia assessment including airway evaluation, review of anticoagulation and imaging, and consent for monitored anesthesia care or general endotracheal anesthesia depending on procedural complexity and patient comorbidities. Induction of anesthesia (general or monitored anesthesia care) occurs in the IR suite with invasive hemodynamic monitoring as needed. During the therapeutic interventional radiological procedure involving the intracranial venous or lymphatic system, the anesthesiologist manages ventilation, hemodynamics, and neurologic monitoring in coordination with the interventional radiologist/neurointerventionalist. Post-procedure, the patient is extubated in the suite or recovered in the post-anesthesia care unit with ongoing neurologic checks and anticoagulation management per the interventional team.
