    ICD-10-CM Code For Conductive And Sensorineural Hearing Loss: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H90 includes conductive, sensorineural, and mixed hearing loss diagnoses affecting one or both ears and specifying laterality and severity. These ICD-10-CM diagnosis codes are used to document clinical presentations of hearing impairment, capturing disease type, laterality, and associated clinical complexity relevant to auditory dysfunction. Accurate coding within the ICD-10-CM H90 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM H90: Conductive And Sensorineural Hearing Loss Overview

    The ICD-10-CM H90 group represents diagnoses of conductive, sensorineural, and mixed hearing loss affecting the ear and auditory system. These codes describe the type and laterality of hearing impairment, targeting disorders of the middle and inner ear. Accurate coding matters for correct reimbursement and to reflect the clinical complexity of hearing loss for claims and medical records.

    When to Use

    Use a code from this group when documenting a clinical diagnosis of hearing loss that has been evaluated and classified as conductive, sensorineural, or mixed, with noted laterality. Select the code that best reflects the clinical findings, severity, and laterality documented in the medical record.

    Typical Clinical Scenarios

    • An older adult presents to primary care with progressive bilateral difficulty hearing conversations in background noise over several years, confirmed by audiometry showing mixed conductive and sensorineural loss with greater sensorineural component on the right. The patient reports gradual decline, uses a hearing aid intermittently, and no acute symptoms are present; a chronic diagnosis code reflecting combined sensorineural and conductive hearing loss is assigned. Typical codes: H90.3, H90.5
    • A child is brought to the emergency department after an acute otitis media with sudden onset unilateral hearing reduction and tympanic membrane perforation; bedside tuning fork exam and urgent audiology suggest predominantly conductive loss in the affected ear. Because this is an acute complication of middle ear disease producing conductive hearing impairment, an appropriate conductive hearing loss code from the group is used. Typical codes: H90.2, H90.0
    • A middle-aged patient with longstanding noise-exposure and diabetes presents for preoperative assessment and is found on audiometry to have asymmetric sensorineural hearing loss worse on the left, complicating communication needs and influencing perioperative planning. The chronic sensorineural deficit related to occupational noise (with comorbid systemic disease) is documented using a sensorineural hearing loss code from the group. Typical codes: H90.41, H90.42
