Other acute nonsuppurative otitis media, left ear

This code signifies an acute inflammation of the middle ear, specifically the left ear, that is not characterized by the formation of pus. It represents a sudden onset of middle ear infection without purulent discharge, often associated with viral infections or allergic reactions.

Use this code when documentation specifies acute, non-suppurative otitis media affecting the left ear. This typically occurs when a patient presents with ear pain, pressure, or hearing changes, and otoscopic examination reveals inflammation of the tympanic membrane without evidence of purulence. Supporting documentation would include physician notes detailing the laterality and absence of suppuration.

• Always confirm laterality (left ear) from the physician's documentation.
• Distinguish carefully from suppurative otitis media (H66.-) which involves pus formation.
• Do not use if the condition is chronic; refer to codes in the H65.2- or H65.3- series for chronic non-suppurative otitis media.
