ICD-10 Code H72.12 – Attic perforation of tympanic membrane, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H72.12 – Attic perforation of tympanic membrane, left ear
What it is
H72.12 identifies a perforation in the attic, or pars flaccida, of the left tympanic membrane. Use it when documentation specifies a left ear attic perforation, not a general eardrum rupture.
Clinical signs
Findings may include a visible attic defect on otoscopy, ear drainage, or conductive hearing loss. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents an attic perforation of the left tympanic membrane, such as during ENT evaluation or otoscopic exam. It is appropriate when the laterality and attic location are both clearly stated. If the note only says “perforated eardrum,” check documentation.
Do not use for
Do not use H72.12 for right ear, bilateral, or unspecified tympanic membrane perforations. Do not use it when the record describes another middle ear disorder without a documented attic perforation.
Coding tip
Verify both attic location and left-sided laterality in the provider note before assigning H72.12.
