National Reimbursement Benchmarks
Medicare’s mean allowed amount is $27.70, notably lower than BUCA’s commercial average of $77.00, indicating Medicare reimburses roughly one-third of this commercial benchmark for CPT 92020. That gap highlights the split between government and commercial purchasing power for this ophthalmology evaluation code, with BUCA sitting well above Medicare on a national mean basis.
Examining dispersion (P75 minus P25) highlights variability by payer: Blue Cross Blue Shield has the widest interquartile spread at $43.20 ($131.70 - $89.50), followed by Aetna at $17.20 ($30.00 - $12.80). UnitedHealth Group and Cigna show similar mid-level spreads of $20.90 ($45.80 - $24.70) and $23.30 ($48.00 - $24.70) respectively, while BUCA’s spread is $32.90 ($92.90 - $60.00). Medicare’s interquartile spread is narrow at $2.00 ($28.00 - $26.00).
