    ICD-10-CM Code For Other And Unspecified Hearing Loss: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H91 includes hearing loss diagnoses that are described as other specified or unspecified, covering conditions such as unspecified sensorineural hearing loss, unspecified conductive hearing loss, and mixed or other specified hearing impairments. These ICD-10-CM diagnosis codes are used to document clinical scenarios where the type, laterality, or etiology of hearing loss is not fully classified, capturing disease severity, organ involvement, or clinical complexity relevant to auditory dysfunction. Accurate coding within the ICD-10-CM H91 group supports proper claim adjudication and complete clinical documentation.

    ICD-10-CM H91: Other And Unspecified Hearing Loss Overview

    The ICD-10-CM H91 group includes diagnoses for hearing loss that are not classified elsewhere or are unspecified in type or laterality. These conditions affect the auditory system and can represent sensorineural, conductive, or mixed patterns when not otherwise specified. Accurate coding matters for clinical records and reimbursement because it supports correct claim adjudication and reflects the level of diagnostic specificity.

    When to Use

    Use a code from this group when a patient has documented hearing impairment but the clinical record does not specify a more precise diagnosis or when the hearing loss is classified as other specified. These codes apply when laterality, etiology, or anatomic detail required for more specific codes is not available in the medical record.

    Typical Clinical Scenarios

    • An older adult patient presents to the primary care clinic with gradual, bilateral decline in hearing over several years, reporting difficulty understanding conversations in noisy environments but no ear pain or recent illness. Audiometric testing demonstrates symmetric sensorineural hearing loss consistent with presbycusis; a diagnosis from this group is assigned to characterize the chronic, age-related sensorineural impairment. Typical codes: H91.10, H91.11
    • A middle-aged patient arrives to the emergency department after an acute onset of unilateral hearing loss following a blast injury at work; examination shows sudden profound loss on the affected side without tympanic membrane rupture. The presentation is an acute, traumatic-related sensorineural hearing loss requiring urgent evaluation, and a diagnosis from this group is used to document the sudden, unilateral nature and cause. Typical codes: H91.01, H91.02
    • A patient with longstanding conductive hearing deficit from chronic otitis media is undergoing preoperative assessment for cochlear implantation due to mixed severe hearing loss refractory to medical and surgical treatment. The hearing impairment is recorded as a comorbidity affecting perioperative planning and long-term rehabilitation, and a specific code from this group is assigned to reflect the mixed or unspecified hearing loss component. Typical codes: H91.20, H91.21
