ICD-10 Code H66.41 – Suppurative otitis media, unspecified, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H66.41 – Suppurative otitis media, unspecified, right ear
What it is
H66.41 identifies a suppurative middle ear infection affecting the right ear. Use it when the record documents purulent otitis media but does not specify a more exact type.
Clinical signs
Typical findings include ear pain, fever, reduced hearing, and otoscopic evidence of middle ear infection with purulent drainage or effusion. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents suppurative otitis media in the right ear and does not name the episode as acute, chronic, or recurrent. It also fits when the chart confirms right-sided involvement but leaves the subtype unspecified. Check documentation if laterality or chronicity is unclear.
Do not use for
Do not use H66.41 for nonsuppurative otitis media, external ear infection, or ear pain without a documented middle ear infection. Do not assume chronic or recurrent disease unless stated.
Coding tip
Confirm both laterality and that the infection is suppurative before assigning H66.41.
