H65.49Other chronic nonsuppurative otitis media

H65.49 is the ICD-10-CM diagnosis code for other chronic nonsuppurative otitis media. It belongs to category H65 (nonsuppurative otitis media), block H65-H75 (diseases of middle ear and mastoid) and chapter 8 (diseases of the ear and mastoid process). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within H65.4, choose H65.49 (Other chronic nonsuppurative otitis media) only when documentation doesn't support a more specific option: chronic allergic otitis media (H65.41).

To report this condition, pick the subcode that matches the documentation: H65.491 (right ear), H65.492 (left ear), H65.493 (bilateral) and H65.499 (unspecified ear).

Use an additional code for any associated perforated tympanic membrane (H72.-). Use an additional code, if applicable, to identify: exposure to environmental tobacco smoke (Z77.22), exposure to tobacco smoke in the perinatal period (P96.81), history of tobacco dependence (Z87.891), infectious agent (B95-B97), occupational exposure to environmental tobacco smoke (Z57.31) and 2 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
