ICD-10 codes for Otitis Media
Otitis Media is coded primarily under H66.90, H65, H66 in the ICD-10-CM (Clinical Modification) classification. Top-level categories include H65 (Nonsuppurative otitis media); H66 (Suppurative and unspecified otitis media); H67 (Otitis media in diseases classified elsewhere). The 2025 ICD-10-CM code set includes 106 codes related to otitis media, of which 84 are billable (specific enough to appear on a medical claim).
Otitis media is middle ear inflammation. ICD-10-CM groups otitis media codes under H65 (nonsuppurative), H66 (suppurative), and H67 (otitis media in diseases classified elsewhere). H66.90 (otitis media, unspecified, unspecified ear) is one of the most common codes used in pediatric primary care.
