H90.4Sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side

H90.4 is the ICD-10-CM diagnosis code for sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side. It belongs to category H90 (conductive and sensorineural 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 2 subcodes must be used instead.

Within H90 (conductive and sensorineural hearing loss), H90.4 is specifically for sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side. Related codes cover conductive hearing loss, bilateral (H90.0), conductive hearing loss, unilateral with unrestricted hearing on the contralateral side (H90.1), conductive hearing loss, unspecified (H90.2), sensorineural hearing loss, bilateral (H90.3), unspecified sensorineural hearing loss (H90.5), mixed conductive and sensorineural hearing loss, bilateral (H90.6), mixed conductive and sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side (H90.7), mixed conductive and sensorineural hearing loss, unspecified (H90.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: H90.41 (side) and H90.42 (side).
