Chronic myringitis without mention of otitis media

This code signifies a persistent inflammation of the tympanic membrane (eardrum) that is not associated with an active middle ear infection. It describes a chronic, localized inflammatory process affecting the eardrum itself, often characterized by thickening, granulation, or other structural changes.

Apply this code when documentation explicitly states "chronic myringitis" without any co-occurring otitis media. This typically occurs after acute otitis media has resolved, or as a primary, long-standing inflammatory condition of the eardrum. Supporting documentation would include otoscopic findings detailing chronic changes to the tympanic membrane.

• Differentiate from acute myringitis (384.0) based on the chronicity documented by the provider.
• Ensure the absence of otitis media is clearly stated or implied; if otitis media is present, a more specific code for the otitis media should be used.
• Do not use this code if the myringitis is described as bullous or hemorrhagic, as those have separate, more specific codes.
