ICD-10 Code H73.819 – Atrophic flaccid tympanic membrane, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.819 – Atrophic flaccid tympanic membrane, unspecified ear
What it is
This code identifies an atrophic, flaccid tympanic membrane in an unspecified ear. It means the eardrum is thinned and lax, without specifying the right or left side.
Clinical signs
Findings may include a thin, retracted, or overly mobile tympanic membrane on otoscopic exam. Clinical features vary; refer to documentation.
When to use this code
Use H73.819 when the record documents atrophic flaccid tympanic membrane but does not identify the ear. It is appropriate for outpatient or inpatient documentation when the clinician notes this specific tympanic membrane change. If the side is documented, code the laterality instead.
Do not use for
Do not use this code for tympanic membrane perforation, acute otitis media, or nonspecific ear pain. Check documentation if the note describes another middle-ear disorder.
Coding tip
Verify laterality in the chart before assigning the unspecified code.
