ICD-10 Code H73.2 – Unspecified Myringitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.2 – Unspecified myringitis
What it is
H73.2 identifies inflammation of the tympanic membrane when the record does not specify the type. Use it when the chart says myringitis but gives no further detail.
Clinical signs
Findings may include ear pain, a red or inflamed eardrum, or a recent ear infection history. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents myringitis without naming a subtype, such as bullous, granular, or hemorrhagic. It also fits when the note confirms tympanic membrane inflammation but does not provide enough detail for a more specific code.
If later documentation clarifies the exact form, report the more specific diagnosis instead. Check documentation before coding from a brief problem list or incomplete encounter note.
Do not use for
Do not use H73.2 for otitis media, otitis externa, or a perforated tympanic membrane unless myringitis is specifically documented. Do not assign it when a different ear disorder is clearly identified.
Coding tip
Query for the exact myringitis type when the note is vague, because unspecified coding should be a last resort.
