ICD-10 Code H66.001 – Acute suppurative otitis media without spontaneous rupture of ear drum, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H66.001 – Acute suppurative otitis media without spontaneous rupture of ear drum, right ear
What it is
This code identifies an acute bacterial middle ear infection in the right ear with pus present, but without a spontaneous eardrum rupture. Use it when documentation clearly states the right-sided location and no perforation.
Clinical signs
Typical findings include ear pain, fever, irritability, and a bulging or inflamed tympanic membrane. Clinical features vary; refer to documentation if the note does not confirm suppuration or laterality.
When to use this code
Use H66.001 when the provider documents acute suppurative otitis media affecting the right ear and specifically notes no spontaneous rupture of the eardrum. It also fits when the diagnosis is confirmed on examination and the record supports the acute infectious process. If the chart is unclear about laterality or perforation, check documentation.
Do not use for
Do not use this code for otitis media with spontaneous tympanic membrane rupture, chronic otitis media, or nonsuppurative middle ear disease. If the diagnosis is only suspected or not documented as right-sided, check documentation.
Coding tip
Always verify both laterality and the absence of spontaneous eardrum rupture before assigning H66.001.
