H75.8Other specified disorders of middle ear and mastoid in diseases classified elsewhere

H75.8 is the ICD-10-CM diagnosis code for other specified disorders of middle ear and mastoid in diseases classified elsewhere. It belongs to category H75 (other disorders of middle ear and mastoid in diseases classified elsewhere), 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 H75, choose H75.8 (Other specified disorders of middle ear and mastoid in diseases classified elsewhere) only when documentation doesn't support a more specific option: mastoiditis in infectious and parasitic diseases classified elsewhere (H75.0).

To report this condition, pick the subcode that matches the documentation: H75.80 (unspecified ear), H75.81 (elsewhere), H75.82 (elsewhere) and H75.83 (bilateral).

Code first: underlying disease.

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