About H68.1

H68.1 is the ICD-10-CM diagnosis code for obstruction of Eustachian tube. It belongs to category H68 (eustachian salpingitis and obstruction), 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 H68 (eustachian salpingitis and obstruction), H68.1 is specifically for obstruction of Eustachian tube. Related codes cover eustachian salpingitis (H68.0).

To report this condition, pick the subcode that matches the documentation: H68.10 (tube), H68.11 (tube), H68.12 (tube) and H68.13 (tube).

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