Use Additional Code
- code to identify pneumonia or other manifestations, such as:
- pneumonia due to COVID-19 J12.82
- code, if applicable, for associated conditions such as:
- COVID-19 associated coagulopathy D68.8
- disseminated intravascular coagulation D65
- hypercoagulable states D68.69
- thrombophilia D68.69
Type 2 Excludes
- coronavirus as the cause of diseases classified elsewhere B97.2
- pneumonia due to SARS-associated coronavirus J12.81
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
