ICD-10 Code H73.812 – Atrophic flaccid tympanic membrane, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.812 – Atrophic flaccid tympanic membrane, left ear
What it is
H73.812 identifies thinning and flaccidity of the left tympanic membrane. Use it when documentation states the eardrum is atrophic, flaccid, or markedly weakened in the left ear.
Clinical signs
Findings may include a thin, retracted, or overly mobile tympanic membrane on otoscopy. Clinical features vary; refer to documentation, especially if the note specifies the left ear.
When to use this code
Use this code when the provider documents atrophic flaccid tympanic membrane of the left ear, or equivalent wording such as a flaccid or atrophic eardrum on that side. It is appropriate when the finding is the diagnosis being recorded, not just a historical detail.
Do not use for
Do not use it for perforated tympanic membrane, acute otitis media, or other middle-ear disorders unless the record also documents left-sided atrophic flaccidity. Check documentation if the ear side is not stated.
Coding tip
Verify laterality carefully; H73.812 is specific to the left ear and should match the provider’s exact wording.
