Bullous myringitis, bilateral

This code signifies an inflammatory condition affecting both eardrums, characterized by the formation of fluid-filled blisters (bullae) on the tympanic membrane. It is typically caused by viral or bacterial infections and can lead to significant ear pain and hearing impairment.

Apply this code when documentation explicitly states "bullous myringitis" affecting both ears. This diagnosis is often made during otoscopic examination, revealing vesicles or bullae on the tympanic membranes of both the left and right ears.

• Ensure documentation specifies "bilateral" involvement; otherwise, a unilateral code (H73.011 or H73.012) or unspecified code (H73.019) would be more appropriate.
• Do not confuse with acute serous otitis media (H65.0-) or other forms of myringitis without bullae.
• Code any underlying infectious agent (e.g., influenza, bacterial infection) as an additional diagnosis, if identified and documented.
