ICD-10 Code H66.13 – Chronic tubotympanic suppurative otitis media, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H66.13 – Chronic tubotympanic suppurative otitis media, bilateral
What it is
This code identifies long-standing, noncholesteatomatous chronic suppurative otitis media affecting both ears. It indicates persistent middle ear inflammation with drainage through a perforated tympanic membrane.
Clinical signs
Typical findings include recurrent or persistent ear discharge, hearing loss, and a history of chronic middle ear infection. Clinical features vary; refer to documentation for laterality, perforation, and whether the process is active.
When to use this code
Use H66.13 when the record clearly documents chronic tubotympanic suppurative otitis media in both ears. It is appropriate when the clinician describes bilateral chronic otorrhea or chronic perforation with middle ear infection. Confirm that the condition is not acute, nonsuppurative, or cholesteatomatous.
Do not use for
Do not use this code for acute otitis media, serous otitis media, or otitis media with effusion. Check documentation if cholesteatoma is present or if only one ear is involved.
Coding tip
Verify bilateral involvement and chronic suppurative wording in the note before assigning H66.13.
