About H93.01

H93.01 is the ICD-10-CM diagnosis code for transient ischemic deafness. It belongs to category H93 (other disorders of ear, not elsewhere classified), block H90-H94 (other disorders of 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.

Within H93.0 (degenerative and vascular disorders of ear), H93.01 is specifically for transient ischemic deafness. Related codes cover unspecified degenerative and vascular disorders of ear (H93.09).

To report this condition, pick the subcode that matches the documentation: H93.011 (right ear), H93.012 (left ear), H93.013 (bilateral) and H93.019 (unspecified ear).

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