ICD-10 Code H73.92 – Unspecified disorder of tympanic membrane, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.92 – Unspecified disorder of tympanic membrane, left ear
What it is
This code identifies a disorder of the left tympanic membrane, or eardrum, when the specific condition is not further described. Use it when documentation confirms a left eardrum abnormality but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an abnormal-appearing left tympanic membrane on otoscopic exam, such as scarring, thickening, retraction, perforation, or other nonspecific changes.
When to use this code
Use H73.92 when the provider documents an unspecified disorder involving the left tympanic membrane and no more specific code is supported. It is appropriate when the record mentions an eardrum abnormality but does not define the exact pathology. You should code the documented laterality only if the left ear is specified.
Do not use for
Do not use this code for middle ear disease, otitis media, or hearing loss alone. If the record identifies a specific tympanic membrane disorder, check documentation and code the more precise diagnosis instead.
Coding tip
Confirm both the ear side and the exact wording in the note before assigning this unspecified code.
