ICD-10 Code H73.003 – Acute myringitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.003 – Acute myringitis, bilateral
What it is
This code identifies acute inflammation of the tympanic membrane in both ears. Use it when documentation specifically states bilateral acute myringitis.
Clinical signs
Typical findings may include ear pain, a red or inflamed eardrum, and hearing discomfort. Clinical features vary; refer to documentation.
When to use this code
Use H73.003 when the provider documents acute myringitis affecting both tympanic membranes. It is appropriate when the record clearly supports a bilateral diagnosis, even if symptoms are not fully detailed.
If the note only says ear pain, otitis media, or eardrum redness without naming acute myringitis, do not assume this code. Check documentation for laterality and the exact diagnosis.
Do not use for
Do not use this code for nonspecific ear infection, otitis media, or chronic tympanic membrane disease. Do not assign it when bilateral involvement is not documented.
Coding tip
Confirm both the acute myringitis diagnosis and the bilateral laterality in the provider note before coding.
