Bullous myringitis, right ear

This code represents an inflammatory condition of the right tympanic membrane characterized by the formation of fluid-filled blisters (bullae) on its surface. It is typically associated with viral infections and can cause significant ear pain and hearing loss.

Use this code when documentation specifically indicates bullous myringitis affecting the right ear. This diagnosis is often made during otoscopic examination, noting the characteristic bullae on the tympanic membrane. Supporting documentation should include the laterality of the condition.

• Ensure laterality is clearly documented (right, left, or bilateral) to select the most specific code.
• Do not confuse with acute serous otitis media or acute suppurative otitis media, which involve fluid in the middle ear space rather than bullae on the tympanic membrane.
• Code any underlying infectious agent (e.g., viral, bacterial) as an additional diagnosis if identified and documented.
