Acute and subacute allergic otitis media (serous), bi

This code signifies inflammation of both middle ears due to an allergic reaction, characterized by the presence of fluid that may be mucoid (thick, sticky), sanguinous (bloody), or serous (thin, watery). It represents an acute or subacute presentation, meaning the condition is of recent onset or has been present for a short duration.

Apply this code when documentation clearly indicates bilateral otitis media with an allergic etiology and specifies the presence of fluid (mucoid, sanguinous, or serous). This is appropriate for patients experiencing symptoms such as ear pain, hearing loss, or aural fullness attributed to an allergic response affecting both middle ears.

• Ensure the documentation explicitly states "allergic" as the cause of the otitis media.
• Confirm the laterality is "bilateral" and the fluid type is specified.
• Distinguish from non-allergic otitis media or chronic conditions, which have different codes.
