Bullous myringitis, left ear

This code signifies an inflammatory condition of the left tympanic membrane characterized by the formation of fluid-filled blisters (bullae). It is typically caused by a viral or bacterial infection and often presents with acute otalgia and hearing loss.

Apply this code when documentation specifically indicates bullous myringitis affecting the left ear. This diagnosis is commonly made during an otoscopic examination revealing characteristic vesicles or bullae on the eardrum.

• Ensure laterality is clearly documented; differentiate between left, right, and bilateral involvement.
• Do not confuse with acute otitis media without bullae, even if the etiology is similar.
• Code any underlying infectious agent (e.g., influenza, bacterial infection) as an additional diagnosis if identified and documented.
