Summary
Blue Cross Blue Shield of Illinois will implement 18 new claims editing rules in July 2026 that will automatically deny or rebundle claims with specific coding errors, including radiation therapy planning, STI testing combinations, colonoscopy injections, and missing modifiers. Claims receiving these edits will show reason codes with 'G' alpha characters.
Action Required
By July 15, 2026: Billing team must update coding practices to comply with 18 new editing rules including proper modifier usage (50, RT, LT, 54), correct diagnosis sequencing, appropriate place of service coding, and bundling requirements for STI testing. Review all radiation therapy, colonoscopy, anesthesia, and DME claims for compliance. Train staff on Clear Claim Connection software to pre-validate claims before submission. Failure to comply will result in automatic claim denials with 'G' reason codes.
