Summary
Independence Blue Cross updated ICD-10 diagnosis codes effective 10/01/2026 for Policy 05.00.77g (Implantable Cardioverter Defibrillators). Three codes were terminated (I42.0, I42.8, I49.8) and nine new codes were added with greater specificity, including new codes for Brugada syndrome (I49.81), catecholaminergic polymorphic ventricular tachycardia (I47.22), ventricular bigeminy (I49.82), and arrhythmogenic cardiomyopathy (I42.81). The policy itself was not fully reviewed; this is a routine annual ICD-10 code update.
Action Required
By 10/01/2026: Billing team must update diagnosis code mapping in billing software to remove terminated ICD-10 codes (I42.0, I42.8, I49.8) and add nine new codes (I42.00, I42.01, I42.09, I42.81, I42.89, I47.22, I49.81, I49.82, I49.89) for all ICD claims submitted to Independence Blue Cross Commercial plans. Update claim validation logic and EMR documentation templates to reflect the new code specificity, particularly for cardiomyopathy and cardiac arrhythmia diagnoses. Providers must ensure claims for ICD procedures (CPT 33216-33241, HCPCS C1721, C1722, C1895, C1896) include only the updated diagnosis codes after the effective date. Claims submitted with the terminated codes after 10/01/2026 will be denied or require resubmission. Train providers on proper code selection for the new granular categories (e.g., I42.01 for familial-genetic dilated cardiomyopathy vs. I42.09 for other dilated cardiomyopathy).
