Adhesive right middle ear disease

This code describes a condition where the right middle ear's structures, such as the ossicles or tympanic membrane, are abnormally bound together by fibrous adhesions. This can restrict movement and impair sound conduction, leading to conductive hearing loss. It represents a chronic inflammatory process resulting in scarring within the middle ear space.

Use this code when documentation specifies adhesive otitis media or tympanosclerosis affecting the right middle ear. This diagnosis is typically made based on otoscopic examination findings, audiometry showing conductive hearing loss, and sometimes imaging. Ensure the laterality (right ear) is clearly documented.

• Differentiate from other middle ear conditions like otosclerosis or cholesteatoma, which have distinct codes.
• Confirm laterality; separate codes exist for left (H74.12) and bilateral (H74.13) involvement.
• If associated with hearing loss, code the hearing loss separately as a secondary diagnosis.
