National Reimbursement Benchmarks
Commercial averages sit notably above Medicare: Blue Cross Blue Shield’s mean ($4,681.10) and BUCA’s mean ($3,158.30) contrast with Medicare’s mean ($756.80), indicating a substantial premium for commercial contracts relative to the federal program. Blue Cross Blue Shield leads on mean compensation, while Medicare’s mean aligns closer to lower-mid commercial tiers such as Aetna and Cigna.
Dispersion measured by the interquartile range (P75–P25) is widest for Blue Cross Blue Shield at $5,087.10, reflecting heavy variation across geographies or contract structures. UnitedHealth Group ($970.20) and Cigna ($1,037.20) show moderate dispersion. The tightest spreads are Aetna ($693.00) and BUCA ($3,294.40), though BUCA’s larger absolute mean means its IQR reflects high but relatively concentrated commercial pricing compared with Blue Cross Blue Shield.
