Conductive and sensorineural hearing loss (H90) ICD-10-CM
The H90 code range covers conductive and sensorineural hearing loss with 26 ICD-10-CM diagnosis codes. 18 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the H90 range.
Dentinogenesis Imperfecta
An autosomal dominant disorder of tooth development characterized by opalescent dentin resulting in discoloration of the teeth. The dentin develops poorly with low mineral content while the pulp canal is obliterated.
Essential Tremor
A relatively common disorder characterized by a fairly specific pattern of tremors which are most prominent in the upper extremities and neck, inducing titubations of the head. The tremor is usually mild, but when severe may be disabling. An autosomal dominant pattern of inheritance may occur in some families (i.e., familial tremor). (Mov Disord 1988;13(1):5-10)
Hypertelorism
Abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.
Narcolepsy
A condition characterized by recurrent episodes of daytime somnolence and lapses in consciousness (microsomnias) that may be associated with automatic behaviors and AMNESIA. CATAPLEXY; SLEEP PARALYSIS, and hypnagogic HALLUCINATIONS frequently accompany narcolepsy. The pathophysiology of this disorder includes sleep-onset rapid eye movement (REM) sleep, which normally follows stage III or IV sleep. (From Neurology 1998 Feb;50(2 Suppl 1):S2-S7)
Wolfram Syndrome
A hereditary condition characterized by multiple symptoms including those of DIABETES INSIPIDUS; DIABETES MELLITUS; OPTIC ATROPHY; and DEAFNESS. This syndrome is also known as DIDMOAD (first letter of each word) and is usually associated with VASOPRESSIN deficiency. It is caused by mutations in gene WFS1 encoding wolframin, a 100-kDa transmembrane protein.
About the H90 Code Range
The ICD-10 codes under section H90 are specifically used to classify different types of hearing loss, including conductive, sensorineural, and mixed forms. These codes help distinguish the hearing loss by laterality—whether it affects one ear or both—as well as by whether the opposite ear's hearing is normal, restricted, or unspecified.
This section covers hearing loss conditions such as conductive hearing loss (e.g., bilateral H90.0 or unilateral H90.1), which involves problems with ear structures like the middle ear. The term "conductive hearing loss" has several synonyms, including "middle ear conductive hearing loss" and "bone conduction deafness," all represented within these codes. It also includes sensorineural hearing loss (e.g., bilateral H90.3 or unilateral H90.4), which refers to damage in the inner ear or auditory nerve and is often noted with synonyms like "neural hearing loss" or "high-frequency sensorineural hearing loss." Additionally, the codes cover mixed hearing loss (e.g., bilateral H90.6 or unilateral H90.7) where both conductive and sensorineural impairments coexist. Specific subcodes delineate the affected ear side and the hearing status of the contralateral ear, enabling precise diagnosis and billing. For example, H90.11 specifies unilateral conductive hearing loss in the right ear with normal hearing on the left side, assisting coders in assigning the accurate ICD-10 code for conditions commonly referred to as "conductive hearing loss of right ear."
Questions About This Page
How many billable codes are in the H90 range?
Of the 26 codes in this range, 18 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.
What does the H90 range classify?
The range classifies conductive and sensorineural hearing loss. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
