About H90.5

H90.5 is the ICD-10-CM diagnosis code for unspecified sensorineural hearing loss. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within H90, choose H90.5 (Unspecified sensorineural hearing loss) only when documentation doesn't support a more specific option: 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), sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side (H90.4), 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.

Don't report H90.5 together with the conditions in its Excludes1 note: abnormal auditory perception (H93.2-) and psychogenic deafness (F44.6).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 389.10 (sensorineural hearing loss, unspecified), 389.14 (central hearing loss) and 389.16 (sensorineural hearing loss, asymmetrical).
