H65 ICD-10-CM Code: Nonsuppurative otitis media

H65 is the ICD-10-CM diagnosis code for nonsuppurative otitis media. H65 sits in the ICD-10-CM chapter for diseases of the ear and mastoid process (h60-h95), within the section covering diseases of middle ear and mastoid (h65-h75).

Header codes like H65 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at H65's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
