H93.09Unspecified degenerative and vascular disorders of ear

H93.09 is the ICD-10-CM diagnosis code for unspecified degenerative and vascular disorders of ear. 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, choose H93.09 (Unspecified degenerative and vascular disorders of ear) only when documentation doesn't support a more specific option: transient ischemic deafness (H93.01).

To report this condition, pick the subcode that matches the documentation: H93.091 (ear), H93.092 (ear), H93.093 (bilateral) and H93.099 (ear).

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