In the ICD-10-CM Tabular List, what does an "Excludes1" note signify?

The excluded code should never be used at the same time as the code above the Excludes1 note, as the two conditions are mutually exclusive.

The excluded condition is not part of the condition represented by the code, but the patient may have both conditions at the same time.
