Illinois downcoding bill passes legislature unanimously

By AI, Created 1:31 PM UTC, May 29, 2026, /AGP/ – Illinois lawmakers approved a bill to curb automatic downcoding by health insurers, sending the measure to Gov. J.B. Pritzker after unanimous votes in both chambers. The Illinois State Medical Society says the change would make claims handling more transparent and give physicians a clearer way to challenge reduced reimbursements.

Why it matters: - Senate Bill 3114 would bar health insurers from automatically assigning a lower billing code than the one that matches the service provided. - Supporters say the change could reduce denied or reduced reimbursements for physicians, especially those treating complex or chronic conditions. - The measure could also make the claims process more transparent for patients and doctors.

What happened: - The Illinois House passed the “Transparency in Downcoding Act” on Wednesday evening by a 111-0 vote. - The Illinois Senate approved the bill unanimously earlier in the month. - The Illinois State Medical Society backed the legislation. - Gov. J.B. Pritzker is expected to review the bill next.

The details: - The bill prohibits a health insurance issuer from using an automated process, system or tool to downcode a claim. - The legislation requires a live person to complete a thorough review of claims and supporting clinical documentation before any downcoding decision is made. - Physicians must be clearly notified when a claim is downcoded and reimbursed at a lower level. - The notice must include the clinical reason for the downcoding. - Health insurers must create a clear and accessible process to dispute downcoded claims. - Appeals must be reviewed by an individual with experience in the medical condition being managed and the services being downcoded. - Reviews must use the most up-to-date AMA CPT® Coding Guideline. - The bill also bars insurers from using downcoding to discriminate against physicians who treat patients with complex or chronic conditions.

Between the lines: - ISMS framed the bill as both a patient-access issue and a physician-workforce issue. - Dr. Tripti Kataria said the measure would bring greater clarity to the claims process and ensure a live person reviews medical claims and clinical documentation. - The unanimous votes suggest little public resistance to tightening insurer billing practices in Illinois.

What’s next: - The bill now awaits action from Pritzker. - If signed, Illinois would add a new consumer- and provider-facing restriction on automated claims reduction. - ISMS said it is hopeful the governor will sign the measure into law.

The bottom line: - Illinois lawmakers unanimously moved to limit automated downcoding, setting up a likely change in how insurers review and pay claims in the state.
