ICD-10 Code H73.82 – Atrophic nonflaccid tympanic membrane (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.82 – Atrophic nonflaccid tympanic membrane
What it is
This code identifies thinning or atrophy of the tympanic membrane that is not flaccid. It describes an abnormal eardrum appearance, not a specific infection or hearing diagnosis.
Clinical signs
Documentation may note a thin, retracted, or scarred tympanic membrane on otoscopy. Clinical features vary; refer to documentation for the exact ear findings and whether hearing symptoms are present.
When to use this code
Use H73.82 when the provider documents atrophic nonflaccid changes of the tympanic membrane, including as an otoscopic finding or chronic ear sequela. It can support coding when the eardrum abnormality is the reason for evaluation. Check documentation if the note mentions another specific middle-ear disorder.
Do not use for
Do not use this code for acute otitis media, perforation, or a flaccid tympanic membrane unless that is specifically documented. If the record is vague, check documentation before assigning H73.82.
Coding tip
Code the documented eardrum abnormality exactly as written and avoid assuming infection or perforation.
