ICD-10 Code H73 – Other disorders of tympanic membrane (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73 – Other disorders of tympanic membrane
What it is
H73 covers disorders of the tympanic membrane, or eardrum, that are not classified elsewhere. Use it when documentation identifies an abnormal eardrum condition but does not specify a more exact code.
Clinical signs
Findings may include a visible abnormality of the tympanic membrane, such as scarring, thickening, or other structural change. Clinical features vary; refer to documentation.
When to use this code
Use H73 when the record states an unspecified or other tympanic membrane disorder and no more specific diagnosis is documented. It may fit cases where the eardrum abnormality is noted on exam but not otherwise classified. Check documentation if the note suggests a separate middle ear or perforation diagnosis.
Do not use for
Do not assign H73 for acute otitis media, tympanic membrane perforation, or other clearly coded ear conditions. If the chart gives a specific diagnosis, use that code instead.
Coding tip
Code the most specific tympanic membrane diagnosis available; if the provider only says “abnormal eardrum,” confirm whether H73 is supported.
