ICD-10 Code H73.892 – Other specified disorders of tympanic membrane, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.892 – Other specified disorders of tympanic membrane, left ear
What it is
This code identifies a documented disorder of the left tympanic membrane that does not fit a more specific ear drum diagnosis. Use it when the record names an unusual or specified membrane abnormality, but not perforation, retraction, or another listed condition.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal otoscopic appearance of the left eardrum, such as scarring, thickening, or another specified structural change.
When to use this code
Use this code when the provider documents a specific left tympanic membrane disorder and no more precise ICD-10-CM option applies. It is appropriate for charted abnormalities limited to the left ear drum, especially when the note rules out common listed diagnoses. Check documentation if the exact membrane condition is unclear.
Do not use for
Do not use this code for nonspecific ear pain, otitis media, or a clearly documented tympanic membrane perforation. If the record supports another named ear drum disorder, code that diagnosis instead.
Coding tip
Verify that the documentation specifies the left tympanic membrane and supports an “other specified” diagnosis before assigning H73.892.
