ICD-10 Code H73.822 – Atrophic nonflaccid tympanic membrane, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.822 – Atrophic nonflaccid tympanic membrane, left ear
What it is
H73.822 identifies thinning or atrophy of the left tympanic membrane that remains nonflaccid. Use it when documentation specifically describes an atrophic, not flaccid, left eardrum.
Clinical signs
Findings may include a visibly thinned or retracted tympanic membrane on otoscopy, with preserved tension rather than flaccidity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atrophic nonflaccid tympanic membrane in the left ear, even if no active infection is present. It may appear in ENT evaluations, follow-up exams, or problem lists where the left-sided membrane abnormality is the stated diagnosis.
Do not use for
Do not use this code for a flaccid tympanic membrane, right ear findings, or unspecified ear involvement. If the note only says “abnormal tympanic membrane,” check documentation.
Coding tip
Code the laterality exactly as documented and avoid assuming the diagnosis from otoscopy alone.
