About coding high frequency deafness

The ICD-10-CM code for high frequency deafness is H91.9 (Unspecified hearing loss).

Within H91, choose H91.9 (Unspecified hearing loss) only when documentation doesn't support a more specific option: Ototoxic hearing loss (H91.0), Presbycusis (H91.1), sudden idiopathic hearing loss (H91.2), Deaf nonspeaking, not elsewhere classified (H91.3) and other specified hearing loss (H91.8).

To report this condition, pick the subcode that matches the documentation: H91.90 (unspecified ear), H91.91 (right ear), H91.92 (left ear) and H91.93 (bilateral).

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