ICD-10 Code H74.0 – Tympanosclerosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H74.0 – Tympanosclerosis
What it is
Tympanosclerosis is scarring and calcification of the tympanic membrane or middle ear. Use this code when the record documents this specific chronic ear change.
Clinical signs
Findings may include visible white, chalky plaques on the eardrum and, in some cases, conductive hearing loss. Clinical features vary; refer to documentation.
When to use this code
Use H74.0 when the clinician diagnoses tympanosclerosis or documents scarring/calcification of the tympanic membrane or middle ear. It may appear after recurrent ear disease, prior infection, or ear procedures, but the diagnosis must be stated in the chart.
Do not use for
Do not use this code for nonspecific ear pain, hearing loss alone, or acute otitis media without documented tympanosclerosis. Check documentation if the note only describes a tympanic membrane abnormality.
Coding tip
Code the condition only when the provider clearly identifies tympanosclerosis, not when it is merely suspected.
