Which instruction in the ICD-10-CM tabular list means "not included here" and indicates a patient may be diagnosed with all conditions at the same time?

In the ICD-10-CM coding system, an "Excludes note" indicates that certain conditions should not be coded together because doing so can lead to redundancy or misrepresentation of the patient’s diagnosis. Specifically, when you see "Excludes1," it means that the condition listed cannot occur with the code in question due to the nature of the diagnoses being mutually exclusive. Conversely, if you come across an "Excludes2" note, it indicates that while the two conditions can exist simultaneously, the coder should still be aware that one does not inherently include the other for coding purposes.

In contrast, "Includes notes" provide additional clarification about the conditions or terms that are considered part of a specific code. They help define the range of diagnoses encompassed by that code, rather than suggesting anything about the exclusivity of various diagnoses.

"Combination codes" are specific codes that capture multiple conditions or a condition along with associated symptoms or manifestations in one single code, simplifying the coding process for complex cases.

Lastly, "Code also notes" inform the coder that additional codes may be necessary to fully capture the clinical picture or related conditions influencing the principal diagnosis.

The understanding of these terms is crucial for accurate coding practices, as they inform the coder about how codes
