ICD-10 Code H73.23 – Unspecified myringitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.23 – Unspecified myringitis, bilateral
What it is
H73.23 identifies inflammation of both tympanic membranes when the type is not specified. Use it when the record documents bilateral myringitis but does not name a more specific form.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the tympanic membranes appear inflamed on otoscopic exam, and the note may mention ear pain, redness, or irritation without further detail.
When to use this code
Use this code when the provider clearly documents bilateral myringitis and no additional detail is available. It also fits when the diagnosis is confirmed, but the chart does not specify a cause, severity, or associated ear condition.
Choose this code only after reviewing the note for a more specific diagnosis. If the record describes another middle ear disorder or a unilateral condition, you should not default to H73.23.
Do not use for
Do not use H73.23 for unilateral myringitis or for nonspecific ear pain without a documented diagnosis. Check documentation if the note instead identifies otitis media, perforation, or another tympanic membrane disorder.
Coding tip
Verify that “bilateral” and “myringitis” both appear in the provider record before assigning H73.23.
