ICD-10 Code H65.90 – Unspecified nonsuppurative otitis media, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.90 – Unspecified nonsuppurative otitis media, unspecified ear
What it is
This code identifies a middle-ear inflammation without pus, but the ear side is not specified. Use it when the record says nonsuppurative otitis media and does not name the right or left ear.
Clinical signs
Typical findings include ear pain, a sense of fullness, muffled hearing, or fluid behind the tympanic membrane. Clinical features vary; refer to documentation.
When to use this code
Use H65.90 when the provider documents nonsuppurative otitis media and does not specify laterality. It also fits when the note confirms middle-ear effusion or inflammation without pus, but the record is incomplete for ear side. Check documentation if acute, chronic, or suppurative terms appear.
Do not use for
Do not use this code for suppurative otitis media, otitis externa, or cases with a clearly documented right or left ear. If the type or laterality is stated, choose the more specific code.
Coding tip
Before assigning H65.90, verify that the chart supports nonsuppurative disease and truly lacks laterality detail.
