2026 ICD-10-CM Diagnosis Code H66.11 – Chronic tubotympanic suppurative otitis media, right ear
What it is
This code identifies a chronic middle ear infection in the right ear with persistent or recurrent drainage through the tympanic membrane. It is used when the tubotympanic type is documented and the right side is specified.
Clinical signs
Typical findings include chronic ear discharge, a perforated eardrum, and conductive hearing loss. Clinical features vary; refer to documentation for laterality, chronicity, and whether active suppuration is present.
When to use this code
Use H66.11 when the provider documents chronic tubotympanic suppurative otitis media in the right ear. It fits encounters where the condition is ongoing or recurrent and the record clearly links it to the right ear. If the note does not specify the ear or type, check documentation.
Do not use for
Do not use this code for acute otitis media, nonsuppurative otitis media, or unspecified chronic ear infection. If the documentation does not confirm the tubotympanic form, check documentation.
Coding tip
Always verify laterality and chronicity in the note before assigning H66.11.
