ICD-10 Code H73.8 – Other specified disorders of tympanic membrane (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.8 – Other specified disorders of tympanic membrane
What it is
H73.8 identifies a tympanic membrane disorder that is not described by a more specific code. It covers other documented abnormalities of the eardrum when the record does not fit a listed condition.
Clinical signs
Findings may include visible tympanic membrane changes such as abnormal appearance, scarring, or other non-specific structural defects. Clinical features vary; refer to documentation.
When to use this code
Use H73.8 when the provider documents a specific tympanic membrane disorder that is not otherwise classified in ICD-10-CM. It is appropriate when the note clearly identifies an eardrum abnormality but does not support a more specific code.
Code from the stated diagnosis, not from symptoms alone. If the chart only says “ear pain” or “abnormal ear exam,” check documentation for the exact tympanic membrane finding before assigning this code.
Do not use for
Do not use H73.8 for perforation, rupture, or other specifically coded tympanic membrane conditions. Check documentation if the diagnosis is better described by a more precise ear disorder code.
Coding tip
Match the code to the provider’s exact wording and avoid defaulting to H73.8 when a more specific tympanic membrane diagnosis is documented.
