What do payers pay radiation-oncology groups in IL?

Across 164 NPIs, the median published rate is 140% of locality-adjusted Medicare (September 2026 files).

Data as of the September 2026 payer files.

Across 31 procedure codes and 3 payers, the median published rate is 140 percent of locality-adjusted Medicare in the September 2026 payer files. UnitedHealthcare publishes the highest median at 164 percent and Cigna the lowest at 134 percent, a spread of 30 points on identical work. 3 of 3 payers sit at or above Medicare. The best-covered row rests on 164 confirmed NPIs, and any combination under five is withheld rather than shown thin. These are contracted amounts the payer published, not what a practice was paid, and every row clears the ghost-rate filter, so each NPI counted here actually billed the code in the Medicare utilization file.

How this is measured

Rates come from each payer's published Transparency in Coverage machine-readable file, filtered to this specialty's codes and to NPIs the CMS Medicare utilization file shows billing that code. Percentiles are computed per payer, code and site of service across those NPIs, then divided by the locality-adjusted Medicare amount for the same code and place. Full methodology.
