ICD-10 Code H73.89 – Other specified disorders of tympanic membrane (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.89 – Other specified disorders of tympanic membrane
What it is
This code identifies a specified tympanic membrane disorder that does not fit a more specific ICD-10-CM category. Use it for documented eardrum abnormalities when the record names a distinct condition but no exact code is available.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an abnormal tympanic membrane appearance on otoscopic exam, such as structural change, scarring, or other described membrane disorder.
When to use this code
Use H73.89 when the clinician documents a specific tympanic membrane disorder that is not otherwise classified in the code set. It may apply when the note clearly describes the eardrum abnormality, but a more precise code is unavailable.
Do not infer the diagnosis from nonspecific ear symptoms alone. You should code from the documented condition, not from pain, hearing loss, or infection unless the record links those findings to the tympanic membrane disorder.
Do not use for
Do not use this code for perforation, rupture, or other separately classified tympanic membrane conditions. Check documentation if the provider describes otitis media, trauma, or a different ear disorder instead.
Coding tip
Confirm the exact wording in the assessment or operative note before assigning H73.89.
