Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the H93 range.
Auditory Recruitment
A condition in which an individual with hearing loss perceives sounds as getting disproportionately louder with increasing sound intensity.
Central Auditory Processing Disorder
A disorder characterized by impairment of the auditory processing, resulting in deficiencies in the recognition and interpretation of sounds by the brain. Causes include brain maturation delays and brain traumas or tumors.
Hyperacusis
An abnormally disproportionate increase in the sensation of loudness in response to auditory stimuli of normal volume. COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; FACIAL NERVE DISEASES; STAPES SURGERY; and other disorders may be associated with this condition.
Tinnitus
A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.
About the H93 Code Range
These ear disorders include tinnitus, abnormal auditory perceptions, acoustic nerve disorders, and degenerative or vascular disorders.
H93.0 separates transient ischemic deafness from unspecified degenerative or vascular ear disorders. H93.2 separates types of abnormal auditory perception, including diplacusis, hyperacusis, and central auditory processing disorder. H93.3 identifies acoustic nerve disorders.
The tinnitus groups separate tinnitus from pulsatile tinnitus. Both distinguish right ear, left ear, both ears, and unspecified ear. The remaining groups identify other specified and unspecified ear disorders; the unspecified group also distinguishes the affected ear.
