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 2027, 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.
Hearing Loss, Conductive
Hearing loss due to interference with the mechanical reception or amplification of sound to the COCHLEA. The interference is in the outer or middle ear involving the EAR CANAL; TYMPANIC MEMBRANE; or EAR OSSICLES.
Hearing Loss, Sensorineural
Hearing loss resulting from damage to the COCHLEA and the sensorineural elements which lie internally beyond the oval and round windows. These elements include the AUDITORY NERVE and its connections in the BRAINSTEM.
Mixed Hearing Loss
Hearing loss characterized by a combination of conductive and sensorineural hearing loss. It is caused by problems in both the inner ear and middle or outer ear.
About the H90 Code Range
Hearing loss here is conductive, sensorineural, or a mix of both. The subdivisions separate these types by whether hearing loss affects both ears or one ear.
For hearing loss in one ear, the codes distinguish right from left and show whether hearing in the opposite ear is unrestricted or restricted. H90.1, H90.4, and H90.7 group the types with unrestricted hearing on the opposite side. H90.A groups the types with restricted hearing there. Separate subdivisions identify hearing loss when these details are unspecified.
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, 2026 through September 30, 2027. 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.
