What it means

An Excludes 1 note in ICD-10-CM means the excluded condition cannot occur with the code being referenced — these are mutually exclusive conditions. For example, if a code has "Excludes 1: congenital cholera (A00.0)" it means a patient cannot have both the referenced condition and congenital cholera simultaneously. Unlike Excludes 2, you cannot bill both codes on the same claim. The distinction matters for correct claim coding and audit compliance.

How to say it

Sentences a patient might use with a doctor, nurse, pharmacist, or insurer:

The Excludes 1 note means I cannot report both of these codes on the same claim.

La nota Excluye 1 significa que no puedo reportar ambos códigos en el mismo reclamo.

My claim was rejected because of an Excludes 1 conflict in the ICD-10-CM coding.

Mi reclamo fue rechazado debido a un conflicto de Excluye 1 en la codificación ICD-10-CM.
