Acute myringitis, bilateral

This code signifies an acute inflammatory condition affecting the tympanic membrane (eardrum) in both ears. It is characterized by the sudden onset of inflammation, often presenting with pain, redness, and sometimes blistering of the eardrum.

Use this code when documentation clearly indicates an acute inflammation of the eardrum affecting both ears. This diagnosis is typically supported by otoscopic examination findings such as erythema, bullae, or granular appearance of the tympanic membrane bilaterally.

• Differentiate from chronic myringitis, which has a separate code.
• Ensure laterality is explicitly documented as bilateral; otherwise, unspecified or unilateral codes may be more appropriate.
• Code any associated otitis media separately if present and documented.
