Antes de codificar un alta del 1 de octubre en adelante

  • Usa la versión vigente en la fecha de alta (hospitalización) o la fecha de servicio (ambulatorio), no la fecha en que codificas. Un paciente dado de alta el 30 de septiembre se codifica con FY2026 aunque lo hagas en noviembre.
  • 15 códigos no desaparecen, pero dejan de ser facturables. CMS los ha desglosado en códigos más específicos, así que siguen resultando familiares en tus listas y plantillas, y una reclamación que los use desde el 1 de octubre se rechaza. Aparecen primero abajo, con los códigos que los sustituyen.
  • La nueva categoría QA1 da códigos propios a los síndromes hereditarios de predisposición al cáncer: síndrome de Lynch (QA1.71), síndromes de cáncer familiar con mutación patogénica de BRCA1 o BRCA2 (QA1.790, QA1.791) y síndrome de Li-Fraumeni (QA1.792). Hasta el 30 de septiembre se codificaban con Z15.09 (susceptibilidad genética a otra neoplasia maligna), que sigue siendo facturable para los demás casos.

Códigos que dejan de ser facturables (desglosados) (15)

Siguen en la clasificación como encabezados de categoría, así que es fácil pasarlos por alto. Codifica el hijo más específico.

Cómo se construye esta página

Los dos conjuntos de códigos salen de los archivos de CMS Code Descriptions in Tabular Order (actualización de abril de 2026 y FY2027), los mismos que usa el buscador de códigos ICD-10. Un código cuenta como nuevo si es facturable en FY2027 y no lo era antes; como desglosado si sigue en la clasificación pero pierde el indicador de facturable; como eliminado si desaparece. Los sustitutos combinan los códigos nuevos que cuelgan del antiguo y las correspondencias de la tabla de conversión de NCHS de FY2027. Las cifras coinciden con la adenda de CMS de FY2027: 190 códigos añadidos y 30 retirados de la lista de facturables.

ICD-10-CM se publica solo en inglés: las descripciones de los códigos son el texto oficial de CMS y se muestran sin traducir.
