ICD-10 codes for otitis media
Otitis media coding needs laterality, acuity, and whether the infection is suppurative or associated with effusion.
Notat writes the note — and suggests these codes
The same FactsContext™ engine that extracts codes here turns the full consultation into a structured clinical note, with each code tied to the sentence that supports it. You review and sign every note.
Try AI-assisted extraction with visible medical context
Paste a note or record audio. Notat’s FactsContext™ engine extracts the raw clinical facts first, then suggests codes from that context so you can inspect the evidence before using anything.

How to use this tool
1
Paste or dictate a de-identified clinical note — a few sentences is enough.
2
Press Get codes. The coding system is fixed on this page.
3
Review each suggested code and its evidence, then copy the codes you agree with.

Evidence stays attached for review.
Paste a clinical note or load an example, then press Get codes. Suggestions appear here with the supporting evidence.
AI suggestions must be reviewed by a clinician before use. Do not paste patient-identifying information into this free tool.

Otitis media ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Code | Description | System |
|---|---|---|
H66.90 | Otitis media, unspecified, unspecified ear | ICD-10-CM |
H66.91 | Otitis media, unspecified, right ear | ICD-10-CM |
H66.92 | Otitis media, unspecified, left ear | ICD-10-CM |
H66.003 | Acute suppurative otitis media without spontaneous rupture, bilateral | ICD-10-CM |
H65.90 | Unspecified nonsuppurative otitis media, unspecified ear | ICD-10-CM |
How to choose the right code
Document right, left, or bilateral ear; acute versus chronic; suppurative versus nonsuppurative; and tympanic membrane rupture when present. Use unspecified codes only when those details are absent.
Documentation example
“Child with fever and left ear pain for 24 hours. Left tympanic membrane erythematous and bulging, no perforation. Right ear normal. Assessment: acute otitis media, left ear; safety-net antibiotic prescription.”
Suggested:
Not direct transcript guessing
FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.
Raw facts stay usable
The clinician can read and reuse the extracted medical context directly, independent of the generated note.
Built for review
AI suggestions are not a substitute for clinician judgment, payer rules, local coding policy, or the official code set.
FAQ
Why does laterality matter for otitis media?
Right, left, bilateral, or unspecified ear changes the H66.- code and improves documentation specificity.
What is the difference between H65 and H66?
H65 covers nonsuppurative otitis media, often effusion-focused, while H66 covers suppurative and unspecified otitis media categories.
Can AI capture ear laterality?
Notat extracts laterality, tympanic membrane findings, fever, rupture, and assessment as clinical facts, then suggests the code with evidence.
