ICD-10 codes for otitis media

Otitis media coding needs laterality, acuity, and whether the infection is suppurative or associated with effusion.

H66.90 billable

Otitis media ICD-10 codes

Start with the primary code, then move to a more specific related code when the documentation supports it.

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

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.

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.

H66.92

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.

FactsContext extracts clinical facts first: diagnoses, symptoms, negatives, findings, test results, medications, and plan decisions.

The clinician can read and reuse the extracted medical context directly, independent of the generated note.

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.
