H82Vertiginous syndromes in diseases classified elsewhere

H82 is the ICD-10-CM diagnosis code for vertiginous syndromes in diseases classified elsewhere. It belongs to block H80-H83 (diseases of inner ear) 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.

To report this condition, pick the subcode that matches the documentation: H82.1 (right ear), H82.2 (left ear), H82.3 (bilateral) and H82.9 (unspecified ear).

Don't report H82 together with the conditions in its Excludes1 note: epidemic vertigo (A88.1).

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.
