Illinois physicians report widespread insurer downcoding

A new Illinois State Medical Society survey finds 72% of physicians say their practices have experienced automatic downcoding of properly documented claims. The findings point to lower reimbursements, rising billing disputes and added pressure on medical practices across the state. Why it matters: - Automatic downcoding can lower payment for care that physicians say was properly documented and actually delivered. - The practice can reduce reimbursements, create billing uncertainty and strain practice finances. - The survey suggests the issue is widespread in Illinois, not isolated to a small number of claims. What happened: - The Illinois State Medical Society released a new report on downcoding among Illinois physicians and healthcare professionals. - More than 330 physicians and healthcare professionals responded to the survey. - ISMS conducted the survey from Jan. 25 to Feb. 25, 2026. - The report says 72% of respondents reported their practice has experienced automatic downcoding of appropriately documented claims. The details: - Downcoding is the automatic assignment of a lower-level billing code by a health insurer that overrides the level of service submitted on a medical claim. - The practice is frequently driven by algorithms or standardized payment policies. - Downcoding can lead to lower reimbursement that does not reflect the time and complexity of treatment provided. - Seventy-seven percent of physicians said they have seen automatic downcoding increase over the past five years. - Seventy-two percent said remittance advice for downcoded claims rarely or never includes a specific reason. - The report says that leaves practices without clear guidance on why a claim was reduced or what information the payer wants to change the decision. Between the lines: - The survey points to a growing gap between how physicians code care and how insurers process payment. - Missing explanations for downcoded claims can make appeals harder and slow revenue recovery. - ISMS is framing the issue as a threat to both patient care and the viability of medical practices. - In a statement, ISMS President Dr. Tripti Kataria said health insurer barriers make it harder to care for patients and endanger practice sustainability. What’s next: - ISMS is directing readers to the full report for more findings and context. - The survey results could add pressure on insurers and policymakers to explain downcoding decisions more clearly. - Illinois physicians are likely to keep pushing for payment transparency and fewer automatic claim reductions. The bottom line: - Illinois physicians say automatic downcoding is common, opaque and getting worse, and they want clearer payment decisions before it further squeezes practice revenue.
