About H91.8
H91.8 is the ICD-10-CM diagnosis code for other specified hearing loss. It belongs to category H91 (other and unspecified hearing loss), 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 1 subcodes must be used instead.
Within H91, choose H91.8 (Other specified 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 unspecified hearing loss (H91.9).
To report this condition, pick the subcode that matches the documentation: H91.8X (loss).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
