ICD-10 Code H73.829 – Atrophic nonflaccid tympanic membrane, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.829 – Atrophic nonflaccid tympanic membrane, unspecified ear
What it is
This code identifies thinning or atrophy of the tympanic membrane, with the eardrum remaining nonflaccid. The ear is not specified, so document laterality if available.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an abnormally thin, retracted, or scarred tympanic membrane on otoscopic exam without flaccidity.
When to use this code
Use H73.829 when the provider documents atrophic nonflaccid tympanic membrane and does not specify right or left ear. It may be appropriate when the diagnosis is based on otoscopic findings alone. Check documentation if the record also mentions perforation, acute infection, or another distinct middle-ear disorder.
Do not use for
Do not use this code for a flaccid tympanic membrane, a perforated eardrum, or acute otitis media. If the ear side is documented, use the more specific code instead.
Coding tip
Verify laterality and whether the membrane is atrophic, nonflaccid, or both before assigning H73.829.
