    National Reimbursement Benchmarks

    Across commercial payers, BUCA’s mean of $65.50 serves as a practical average for CPT 01173, with individual carriers diverging around that level. Cigna and UnitedHealth Group sit on opposite ends of the mean spectrum: Cigna’s mean is $92.80 while UnitedHealth Group’s mean is $67.30, and Aetna and Blue Cross Blue Shield cluster below Cigna with means near $59.10 and $58.10 respectively. This positions BUCA slightly below Cigna but above Aetna and Blue Cross Blue Shield in terms of average commercial reimbursement.

    Dispersion measured by the interquartile range (P75–P25) highlights variability: Blue Cross Blue Shield’s IQR is $33.60 ($72.50–$40.90) and Aetna’s IQR is $41.40 ($78.00–$36.60), indicating moderate spread. UnitedHealth Group’s IQR is $28.80 ($80.80–$52.00), the tightest among listed payers. Cigna shows the widest IQR at $53.30 ($120.00–$67.70), signaling the greatest middle-range variability in commercial rates for this code.

    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old male presents with a displaced pelvic fracture involving the acetabulum after a motor vehicle collision. He is scheduled for an open reduction and internal fixation (ORIF) of the pelvic ring and acetabular column under general anesthesia. Preoperative evaluation in the preoperative clinic documents a history of right knee osteoarthritis with a prior right total knee arthroplasty (Z96.651), well-controlled hypertension, and ASA physical status P3. The anesthesia team (anesthesiologist or Certified Registered Nurse Anesthetist) conducts a focused airway assessment, reviews imaging and baseline labs, obtains informed consent for anesthesia risks, and plans for arterial line placement and possible central venous access due to anticipated blood loss and potential prolonged case duration.

    Intraoperative workflow includes induction of general endotracheal anesthesia, placement of invasive monitoring, standardized multimodal analgesia including regional nerve block or neuraxial adjunct if indicated, active warming, fluid and blood product management, and coordination with the surgical team for timed additional procedures. Postoperatively the patient is transferred to the post-anesthesia care unit (PACU) with orders for pain control, thromboprophylaxis, and monitoring for hemorrhage or hemodynamic instability. If extended postoperative anesthesia care is needed (e.g., return to OR for revision), appropriate anesthesia modifiers and documentation are applied.
