Acute upper respiratory infections of other multiple sites

This code signifies an acute infection affecting multiple parts of the upper respiratory tract, such as the nose, pharynx, larynx, and/or sinuses, that are not specified elsewhere. It represents a widespread, sudden onset inflammation of these interconnected structures.

Use this code when documentation indicates an acute upper respiratory infection impacting several unspecified sites, such as "acute upper respiratory infection involving multiple areas" or "generalized acute URI." It is appropriate when the physician's assessment points to a broader infection rather than a localized one.

• Do not use if a more specific code for a localized acute upper respiratory infection (e.g., acute sinusitis, acute pharyngitis) can be assigned.
• Ensure documentation explicitly states involvement of "multiple sites" or "other multiple sites" within the upper respiratory system.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
