Code first

Code the underlying condition first, then this code.

• , if applicable, associated influenza (J09.X1, J10.0-, J11.0-)

Use additional code

Add a second code for the following, when documented.

• code, if applicable, to identify resistance to antimicrobial drugs (Z16.-)

Code also

A second code may be needed. Sequencing depends on the encounter.

• , if applicable, any associated condition such as:
• aspiration pneumonia (J69.-)
