Adhesive middle ear disease, unspecified ear

This code signifies a condition where the middle ear structures, such as the ossicles or tympanic membrane, are abnormally bound together by fibrous adhesions. This can restrict the normal movement of these structures, leading to conductive hearing loss. It represents a non-specific diagnosis of adhesive otitis media without further detail on the specific ear affected.

Use this code when documentation indicates the presence of adhesive middle ear disease, but the medical record does not specify whether it affects the right or left ear, or if it is bilateral. This diagnosis is typically supported by otoscopic examination findings, audiometry results showing conductive hearing loss, and sometimes imaging studies.

• Avoid using this code if the laterality (right, left, or bilateral) is clearly documented; instead, choose a more specific code from the H74.1- subcategory.
• Ensure documentation supports the "unspecified ear" aspect; if the ear is mentioned, even implicitly, a more precise code is required.
• Consider co-reporting with codes for associated symptoms like conductive hearing loss (H90.0-) if documented and not inherent to the adhesive disease.
