ICD-10 Code H66.011 – Acute suppurative otitis media with spontaneous rupture of ear drum, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H66.011 – Acute suppurative otitis media with spontaneous rupture of ear drum, right ear
What it is
This code identifies a right-sided acute middle ear infection with pus and a spontaneous perforation of the tympanic membrane. Use it when the documentation clearly states both suppurative otitis media and rupture of the right eardrum.
Clinical signs
Typical findings include ear pain, fever, decreased hearing, and drainage from the affected ear after the drum ruptures. Clinical features vary; refer to documentation.
When to use this code
Use H66.011 when the provider documents acute suppurative otitis media in the right ear with spontaneous rupture of the eardrum. It also fits notes describing otorrhea from a ruptured right tympanic membrane due to acute infection. Check documentation if laterality or rupture is unclear.
Do not use for
Do not use this code for otitis media without rupture, non-suppurative disease, or left/unspecified ear documentation. Do not assign it if the perforation is traumatic or postsurgical rather than spontaneous.
Coding tip
Confirm right-ear laterality and spontaneous rupture in the same record before you code H66.011.
