What good radiology billing execution looks like for Illinois providers.

The Illinois radiology billing market has its own quirks. Here is the operating discipline we install on every Illinois engagement.

  1. Professional / technical component (26 / TC) disciplineRadiology billing requires precise 26 (professional read) vs TC (technical equipment + staff) split per encounter. Illinois radiology practices and imaging centers need clean component billing.
  2. Autonomous coding for radiology reportsRadiology is one of the most mature specialties for autonomous coding, because structured reports and standardized terminology give the coding engine consistent input.
  3. Prior authorization for advanced imagingMRI, CT, PET, and nuclear medicine require PA from most commercial payers, often through radiology benefit managers (AIM, eviCore). Illinois imaging centers need PA automation tuned for RBM workflows.
  4. AUC status: rescinded, off the claimCMS paused the Medicare Appropriate Use Criteria program and rescinded its regulation at 42 CFR 414.94, effective January 1, 2024, so no decision support consultation, G-code or modifier is reported. Payer and benefit manager imaging criteria still apply. Read the 2026 radiology billing brief.
  5. Interventional radiology procedure codingIR procedures carry complex code stacks (radiologic supervision + interpretation, embolization, biopsy, drainage) with bundling rules. Specialty coders required.
  6. Multi-procedure payment reduction (MPPR) awarenessMPPR reduces payment on second and subsequent radiology procedures on the same date of service. Illinois radiology billing needs MPPR-aware revenue forecasting.
