Summary
Independence Blue Cross updated ICD-10 diagnosis codes for policy MA05.027f effective 10/01/2026. Six codes were removed (I42.0, I42.8) and six new codes were added (I42.00, I42.01, I42.09, I42.81, I42.89, I47.22) to align with the 2026 ICD-10 code set update. This is a routine annual coding maintenance with no changes to coverage criteria or clinical requirements.
Action Required
By September 30, 2026: Billing team must update diagnosis code mappings in the billing system to remove outdated codes (I42.0, I42.8) and implement new granular codes (I42.00, I42.01, I42.09, I42.81, I42.89, I47.22) for ICD claims under policy MA05.027f. Update encoder software and any internal code reference documents used by billing and coding staff. Test claims submission with new codes before the effective date. Communicate changes to providers and clinical documentation staff to ensure proper diagnosis code selection. Claims submitted after 10/01/2026 using terminated codes will be subject to denial or delay.
