ICD-10 Code H74.01 – Tympanosclerosis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H74.01 – Tympanosclerosis, right ear
What it is
Tympanosclerosis, right ear means scarring and calcified plaque formation in the right tympanic membrane or middle ear. It reflects prior inflammation or injury and may be found incidentally or during hearing evaluation.
Clinical signs
Findings may include visible white, chalky plaques on otoscopy and possible conductive hearing loss. Clinical features vary; refer to documentation.
When to use this code
Use H74.01 when the provider documents tympanosclerosis specifically in the right ear. It is appropriate when the condition is confirmed on exam, audiology workup, or specialist assessment. Code the documented laterality, and check documentation if both ears or the middle ear are involved.
Do not use for
Do not use this code for nonspecific ear scarring without a diagnosis of tympanosclerosis. Do not assign it if the record only mentions hearing loss, otitis media, or tympanic membrane changes without clear confirmation.
Coding tip
Verify laterality in the note, because tympanosclerosis has separate codes for right, left, and unspecified ear.
