ICD-10 Code H73.22 – Unspecified myringitis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.22 – Unspecified myringitis, left ear
What it is
H73.22 identifies inflammation of the left tympanic membrane when the record does not specify a more exact type. Use it when the diagnosis is myringitis and the left ear is documented.
Clinical signs
Typical findings may include ear pain, redness, or irritation of the tympanic membrane. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents unspecified myringitis affecting the left ear and does not name a different ear condition. It also fits when the note confirms tympanic membrane inflammation but gives no further subtype. Check documentation if otitis media or another diagnosis is also considered.
Do not use for
Do not use it for right ear or bilateral disease, or when a more specific myringitis code is documented. Avoid it if the chart supports a different ear disorder instead of myringitis.
Coding tip
Match the laterality exactly as documented, and query for specificity if the note only says “myringitis” without the ear side.
