ICD-10 Code H66.004 – Acute suppurative otitis media without spontaneous rupture of ear drum, recurrent, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H66.004 – Acute suppurative otitis media without spontaneous rupture of ear drum, recurrent, right ear
What it is
This code identifies a recurrent episode of acute suppurative otitis media in the right ear, with pus formation but no spontaneous rupture of the tympanic membrane. Use it when the documentation clearly states the right side and recurrence.
Clinical signs
Typical findings include ear pain, fever, irritability, and a bulging, inflamed tympanic membrane on otoscopic exam. Clinical features vary; refer to documentation.
When to use this code
Use H66.004 when the record documents recurrent acute suppurative otitis media affecting the right ear and specifically notes no spontaneous eardrum rupture. It fits encounters based on provider diagnosis, not just symptoms alone. If laterality or recurrence is missing, check documentation.
Do not use for
Do not use this code for otitis media with spontaneous rupture, chronic suppurative otitis media, or nonsuppurative ear infections. Do not assign it when the side is not right or recurrence is not documented.
Coding tip
Verify three elements in the note: recurrent, right ear, and without spontaneous rupture.
