ICD-10-CM Code H90.42
Sensorineural hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.H90.42 is a billable ICD code used to specify a diagnosis of sensorineural hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H904 is used to code Sensorineural hearing loss
Sensorineural hearing loss (SNHL) is a type of hearing loss, or deafness, in which the root cause lies in the inner ear (cochlea and associated structures), vestibulocochlear nerve (cranial nerve VIII), or central auditory processing centers of the brain. SNHL accounts for about 90% of hearing loss reported. A hallmark of such hearing loss is that it is asymmetrically distributed usually toward the high frequency region, or may have a notch at some frequency. SNHL is generally permanent and can be mild, moderate, severe, profound, or total.

Equivalent ICD-9 Codes GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code H90.42 and a single ICD9 code, 389.17 is an approximate match for comparison and conversion purposes.
