About H75
H75 is the ICD-10-CM diagnosis code for other disorders of middle ear and mastoid in diseases classified elsewhere. It belongs to 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 2 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: H75.0 (elsewhere) and H75.8 (elsewhere).
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.
