5 Conclusion
Syndrome-specific ICD-10 codes for monogenic epilepsies are markedly underutilized, even for patients with confirmed molecular diagnoses and established clinical syndromes. In our cohort, fewer than two-thirds of eligible patients were ever documented with their syndrome-specific ICD-10 code, and when used, these codes were applied inconsistently across encounters, specialties, and time. Such gaps hinder the reliable identification of patients for precision therapies, clinical trials, and research studies, limiting the intended value of these codes.
