ICD-10 Code H73.91 – Unspecified disorder of tympanic membrane, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.91 – Unspecified disorder of tympanic membrane, right ear
What it is
This code identifies a documented disorder of the right eardrum when the exact condition is not specified. Use it when the record confirms tympanic membrane abnormality but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an abnormal tympanic membrane appearance on exam, such as scarring, retraction, perforation, or other nonspecific changes.
When to use this code
Use H73.91 when the provider documents a right tympanic membrane disorder without further detail. It is appropriate when the chart notes an eardrum abnormality but does not identify a specific disease process. If the record later clarifies the condition, code the more specific diagnosis.
Do not use for
Do not use this code for acute otitis media, otitis externa, or a clearly documented perforated tympanic membrane with a more specific code. Check documentation if the abnormality is described only as ear pain or hearing loss.
Coding tip
Code the right ear only when laterality is documented; otherwise, verify whether a more specific tympanic membrane diagnosis is available.
