In the ICD-10-CM coding system, what notation is found just under code E16.0 in the Tabular List?

In the ICD-10-CM coding system, the notation found just under code E16.0 in the Tabular List indicates "Use additional" to provide specific instructions regarding coding. This notation is crucial as it informs the coder that there are additional codes that may need to be assigned to capture the complete clinical picture of the patient's condition.

When "Use additional" is indicated, it usually suggests that there is a related condition or situation that should be documented alongside the primary diagnosis to provide more context, enhance the accuracy of the coding, and ultimately improve data quality for treatment and statistical purposes. This structure ensures that healthcare providers have a comprehensive view of the patient's health status, which can be essential for treatment, billing, and reporting purposes.

The other options do not serve the same purpose. For instance, "Use secondary" is related to coding conventions rather than directly referring to coding additional relevant conditions. "Do not code" indicates situations where certain conditions or symptoms should not be coded, limiting the coders' options rather than expanding them. "Code also" implies a similar meaning to "Use additional" but typically has a different coding function regarding the necessity of including multiple codes. Therefore, "Use additional" is the correct notation under E16
