National Reimbursement Benchmarks
Nationally, Medicare’s mean rate of $825.50 for CPT 93457 sits well below BUCA’s average commercial mean of $3,225.80, indicating a substantial gap between federal reimbursement and this commercial benchmark. That difference of $2,400.30 highlights how much higher BUCA’s commercial contracting can be compared with Medicare; other commercial payers’ means cluster between these endpoints, with Aetna at $967.00 and UnitedHealth Group and Cigna near $1,384.50 and $1,381.50 respectively.
Dispersion measured as the interquartile spread (P75–P25) varies notably: Blue Cross Blue Shield shows the widest IQR at $5,128.70 ($6,661.50–$1,532.80), reflecting very high variability across contracts, while Aetna’s IQR is relatively tight at $700.90 ($1,256.00–$540.10). UnitedHealth Group ($1,049.00) and Cigna ($1,169.90) show moderate dispersion; BUCA’s IQR is $3,348.50 ($4,508.70–$1,160.20), and Medicare’s IQR is $800.00 ($1,159.00–$359.00).
