ICD-10 Code H73.893 – Other specified disorders of tympanic membrane, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.893 – Other specified disorders of tympanic membrane, bilateral
What it is
This code identifies a bilateral tympanic membrane disorder that is specified in the record but does not fit a more specific ICD-10-CM category. Use it when both eardrums are affected and the documentation names another defined abnormality.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible tympanic membrane abnormality on otoscopic exam, such as scarring, thinning, or other described structural change affecting both sides.
When to use this code
Use H73.893 when the provider documents a bilateral tympanic membrane disorder and no more specific code applies. It is appropriate when the note clearly describes the condition but does not match perforation, rupture, or another named diagnosis. Check documentation if laterality or exact disorder is unclear.
Do not use for
Do not use this code for unilateral tympanic membrane disorders or for conditions with a more specific ICD-10-CM code. Avoid it when the record only says ear pain, otitis media, or a perforated eardrum without a qualifying specified disorder.
Coding tip
Confirm both laterality and the exact tympanic membrane abnormality before assigning H73.893.
