National Reimbursement Benchmarks
Medicare’s mean rate of $39.5 sits well below BUCA’s average commercial mean of $188.7, indicating a sizable gap between public and that commercial benchmark for CPT 96138. That gap of $149.2 highlights how commercial reimbursement can be multiple times higher than Medicare for this behavioral assessment code, with Medicare values clustered (median $39, P25 $36, P75 $41) compared with the broader commercial average.
Dispersion measured as P75 minus P25 is narrowest for Aetna at $13.6 and for Medicare at $5, reflecting tight clustering around their central tendencies. The widest dispersion appears with Blue Cross Blue Shield at $48.9 and BUCA at $38.5, signaling substantial variability among commercial contracts; UnitedHealth Group ($35.2) and Cigna ($24.9) fall in between. These ranges illustrate where payers exhibit consistent versus highly variable payment behavior for this CPT.
