Frequently asked questions

How do Illinois internal medicine rates compare with the rest of the country?

Illinois ranks 31st of 51 states with an index of 94; 6 of 25 codes are above the national median.

Which internal medicine code has the biggest premium in Illinois?

CPT 93000 (Electrocardiogram complete), at 114% of the national median.

Are these Medicare or commercial rates?

Commercial in-network negotiated rates from four national payers' published files; the Medicare comparison column uses the CY2026 Medicare physician fee schedule.

Methodology

How these numbers are calculated
  • Source: in-network negotiated-rate files published under the federal Transparency in Coverage rule, August 2026 snapshot: UnitedHealthcare Choice plans (74 files); Aetna commercial plans (70 files); Cigna national PPO (1 files); BCBS licensees' own-network files (5,387 files). Payer comparisons describe these files, not each payer's entire book of business.
  • Sample: rates come from a random sample of up to 150 providers per state and specialty. Counts on this page are sampled providers and TINs, not totals.
  • Which providers count: only providers in a specialty relevant to the code, because a rate in a payer file attaches to a provider group and is listed under every provider in that group.
  • Filters: fee-for-service, professional billing class, no modifier, negotiated or fee-schedule dollar rates. Rates outside 1% to 1,000% of the Medicare rate are excluded.
  • Statistic: one median rate per provider, then percentiles across providers. A cell is shown only with at least 15 sampled providers and 4 TINs.
  • Medicare benchmark: CY2026 national physician fee schedule, non-QPP conversion factor, unadjusted for locality. Where the non-facility rate is more than twice the facility rate (office rates that include device or supply cost), the facility rate is used so comparisons are like for like.
