BUCA (average commercial) sits near the center of the national commercial distribution for CPT 00211 with a mean of $72.30 and an interquartile context consistent with other national payers. Among named commercial carriers, Cigna posts the highest mean at $93.10 while Blue Cross Blue Shield averages $64.30 and UnitedHealth Group averages $67.30; Aetna’s mean is $80.50. This positions BUCA as a moderate anchor between Cigna’s upper-tier pricing and BCBS/UnitedHealth Group’s mid-tier levels.

Dispersion measured by the interquartile range (P75 minus P25) is widest for Cigna at $53.20 (P75 $119.90 minus P25 $67.70), indicating greater variability in commercial contract rates, while UnitedHealth Group is the tightest at $27.80 (P75 $80.80 minus P25 $52.00). Blue Cross Blue Shield and Aetna show intermediate dispersion of $39.00 and $53.00 respectively, with BUCA’s IQR at $41.10, reflecting moderate spread around the average commercial rate.

Clinical Context

A 62-year-old male with atrial fibrillation on anticoagulation presents to the emergency department with acute-onset right-sided weakness and decreasing level of consciousness. CT head demonstrates a left-sided acute subdural hematoma with midline shift requiring urgent evacuation via a small craniotomy (burr hole/craniectomy) to remove the clot. The anesthesia team (Anesthesiology or Critical Care Medicine) evaluates the patient preoperatively for airway risk, hemodynamic instability, anticoagulation reversal status, and intracranial pressure management. General endotracheal anesthesia with invasive arterial monitoring and central venous access is induced in the operating room; anesthetic care includes neuroanesthesia techniques (controlled ventilation to target PaCO2, maintenance of cerebral perfusion pressure, and timely emergence planning). Postoperative handoff to the neurosurgical intensive care unit includes documentation of anesthetic agents, intraoperative events (blood loss, transfusions, vasoactive medications), and recommendations for postoperative monitoring and pain control. This scenario corresponds to anesthesia for intracranial procedure to remove a hematoma as described by 00211.
