National Reimbursement Benchmarks
Medicare’s mean of $82.8 sits well below BUCA’s average commercial mean of $1,554.6, highlighting a large gulf between federal reimbursement and what a BUCA commercial mix yields for CPT 93503. This gap underscores how Medicare pricing benchmarks a lower baseline while certain commercial cohorts capture substantially higher average payments, with BUCA’s mean roughly $1,471.8 higher than Medicare’s mean.
Dispersion measured by the interquartile range (P75−P25) is widest for Blue Cross Blue Shield at $957.9 (P75 $3,232.2 minus P25 $2,275.3), followed by BUCA with a spread of $587.2 (P75 $1,925.2 minus P25 $1,337.2). Narrowest spreads appear with Aetna at $79.0 and Cigna at $113.6, while UnitedHealth Group’s IQR is $96.1, indicating relatively tighter clustering for those payers compared with the wider commercial variability seen in Blue Cross Blue Shield and BUCA.
