National Reimbursement Benchmarks
National commercial rates for CPT 00670 center around BUCA’s average commercial benchmark of $82.60, with individual commercial payers showing meaningful variation. Blue Cross Blue Shield’s interdecile spread (P75–P25) is $34.50, Cigna’s spread is $52.20, Aetna’s spread is $53.00, and UnitedHealth Group’s spread is $27.00, indicating Cigna and Aetna exhibit the widest mid‑distribution dispersion while UnitedHealth Group and Blue Cross Blue Shield are comparatively tighter.
Beyond dispersion, payers also differ in central tendency: Blue Cross Blue Shield and UnitedHealth Group sit below BUCA’s average commercial benchmark on mean rates, while Cigna and Aetna have higher mean benchmarks. These differences reflect a mix of tighter contracted ranges for some payers and broader variability for others, with the largest P75–P25 gaps implying more heterogeneity in allowed amounts across locations or contracts.
